SA's gold mines to report low Q1 report

Reports show that South Africa's three big gold miners are due to report drops in production in the first three months of this year. However, earnings look to be lifted for at least two of the companies, because of other factors.

The three have already forecasted earnings and output for their investors. Production looks to be down,a s seasonal factors, such as the slow restart after the festive season, however, analysts are reporting that even by normal Q1 standards, things seem rather slow.

Stephen Roelofse, an analyst for Metropolitan Asset Management states that "it's a slow start and it's seasonal, but it seems to be an exceptionally slow start ... and the June quarter will also be slow because of all the public holidays we've just had."

Silver and Gold fall for third day

Wednesday marked the start of a sharp fall in silver prices, as it fell by 5% and brought gold down along with it

Silver is now showing a loss of 20%, a striking comparison to the record high of last Thursday's $50 an ounce. As expected, Gold has also marked it's worst three-day fall since Januaray, regardless of a broad dollar drop and an increase of gold reserves in Mexico.

Despite a sharp pullback, silver is still one of the top-performing commodities of the year with a 30 percent gain.

However, investors remain cautious of a market in an extremely volatile state.

 
godfather

WEF houses the Godfather's associates?

Activists have labelled the World Economic Forum (WEF) as a platform for gangsters wanting to advance their own personal agenda.

I must admit, when reading this I wondered at the psychological standing of these activists. While revolting against any organisation is well within our rights, who (in a fit state of mind) would label the WEF as gangsters?

Cape Town is currently holding the three-day economic forum, which takes place at the Cape Town International Civic Centre. According to the Workers International Vanguard League's spokesperson, Shaheed Mahomed, the South African government shouldn't allow the forum to take place and the delegates aren't interested in Africa's advancement at all.

“Why do we say the WEF is a bunch of gangsters? While you look at the major strategic partners its Wal-Mart who is renowned around the world of bashing unions creating a non-union environment for greater exploitation of workers,” he said.

“These are people who are here to plunder and in fact one of their sinister campaigns is to say there is too much voting, too little voice. In other words they are saying they want to restructure democracy," he said.

“They say democracy is not suitable for Africa in other words, they are paving the way for the dictatorship of the 50s and 60s to come back to Africa," said Mahomed.

I can't say that, after hearing his comments, I find logic in his accusation. I'm sure that there are those delegates that attend the forum for their own means alone, but I await the arrival of the Godfather before I label them gangsters.

If you have any thoughts, let us know on our WEF forum.

Advanced tamping device a godsend to the mining industry
Tamping is a legal requirement, designed to contain and distribute explosive energy in the blast hole, reducing the risk of fire hazard.
It maximises the effect of an explosion, concentrating it into the rock instead of allowing expanding gases to escape through the blast hole. Clay plugs are most commonly used, but when a misfire occurs, they are notoriously difficult to remove. This is not only time consuming, but costly.
Booyco Electronics has developed an ingenious solution to overcome these problems and provide considerable added advantages which have been enthusiastically welcomed by the mining industry.
Booyco Electronics’ patented Advanced Tamping Device is mechanical and therefore not subject to human error, which makes it by far the preferred method for both management and labour, since no preparation is necessary and it is simple and easy to apply.

Self leveling wet drum separators
Five self leveling wet drum separators have been commissioned at New Clydesdale Coal by Multotec Magnetics, and are achieving 99.1 percent efficiency at this Exxaro mine which exports 95 percent of its coal product.
Developed and introduced to the South African market by Multotec Magnetics, these self leveling wet drum separators are capable of handling fluctuating flow rates and were considered suitable for the New Clydesdale Coal plant as feed rates vary to the plant.
These separators are suitable for plants with inconsistent feed rates due to plant blockages or water quality issues. If the volumetric flow rate has the potential for fluctuating then a self levelling magnetic drum separator is a more forgiving device and will prevent the loss of pulp level in the tank and the losses of magnetite.

Flygt sumersible slurry pumps contribute to reduced costs
Slurry handling is considered one of the most demanding applications for any pump, and one of the costliest in terms of wear and tear, maintenance and downtime. Finding a solution to this problem will result in increasing efficiencies and productivity as well as an exponential reduction in costs. According to Klint Bawden, dewatering applications engineer at ITT Water & Wastewater, there is a market trend away from vertical spindle sump pumps towards submersible slurry pumps. He points out that because the submersible pump operates directly in the slurry it requires no support structure and occupies less space. In addition, the motor and volute is an integrated unit, making it compact and easy to install. Another advantage, because it operates underwater, is the reduced noise level.

Energy efficient spherical roller bearings
BMG’s range of high performance, energy efficient NSK HPS spherical roller bearings has a running life nearly double that of conventional bearings of the same size.
Other advantages of the HPS range include reduced maintenance costs, energy savings and downsizing in product design. The maximum limiting running speed of these spherical roller bearings has also improved by 20 percent.
NSK also applies a special nit-riding treatment on the surface of the cage which forms a finer, harder and more uniform surface than on conventional bearings. This surface treatment increases strength and minimises heat and friction. Maximum limiting speed is significantly increased and cage wear in harsh operational applications is reduced. This special cage design eliminates the need for a guide ring, allowing for the placement of additional larger rollers which in turn increases load capacity.

Non-slip grating in the forefront of innovation
Andrew Mentis, leading engineering and manufacturing company, is living up to its reputation for innovation with its patented non-slip grating which is set to replace serrated grating completely.
The non-slip characteristics have been obtained through the positive raised sections which create multi-directional obstructions on the top of each bearer bar. “Unlike serrated grating,” claims marketing manager, Elaine van Rooyen, “The loading capability of non-slip grating has not been compromised, so this positive profile grating is quickly becoming a leader in the market.”
The non-slip characteristics are effective in all direction, in all finishes and work well on both leather and rubber soled shoes. The self-cleaning properties circumvent the dirt build-up which occurs with serrated grating. The positive-profile non-slip grating concept was applied to the well-known Mentis Rectagrid RS40 grating and is designed to allow a far larger surface contact area.

Energy efficient screw technology blowers
Atlas Copco announces its new and proven energy-efficient technology for air blowing applications: the ZS screw blower.
Screw technology on average is 30 percent more energy-efficient compared to lobe technology. Atlas Copco is convinced that the lobe technology, widely used at present, no longer meets the needs of today’s low carbon economy. Industries and applications such as wastewater treatment, pneumatic conveying, power generation, food and beverage, pharmaceuticals, chemicals, pulp and paper, textiles, cement, and general manufacturing will highly benefit from energy savings through replacing the conventional lobe with the leading screw technology. The ZS screw blower will replace the company’s entire range of ‘Roots’ type rotary lobe blowers.

Suppressing fire in an instant
A group of veteran fire equipment design engineers in the USA have developed a system that is foolproof, cost effective and stops fires almost as soon as they start.
Fire De Tec is both a detection and suppression system in one. It consists of polymer tubing that ruptures when exposed to flame. The Fire De Tec tubing combines leak resistance, flexibility, durability and precise heat sensitivity causing valves in the tube open automatically and extinguish the flames in situ where the fire starts. It does not require expensive control panels, or electrical connections, and is the most cost effective automatic fire suppression available. It is a simple design that can be installed by anyone in a short space of time and can be matched with any fire suppression agent such as foam and dry chemical.

Master SH takes your dewatering to new heights.
Grindex, a world leader in electrical submersible pumps, is now introducing a drainage pump with the capability to deliver water up to over 80 meters in one single step.
It comprises all the features known from the other Grindex dewatering pumps, giving tripled wear resistance compared to earlier pump generations.
Compared to earlier pump generations, the pumps wear resistance has been tripled, in some applications even more. This has been achieved by preventing abrasive particles from reaching the vulnerable parts of the pump, thus minimising wear. The newly designed hydraulics section with its closed double stage impellers dramatically reduces the performance drop caused by long-term wear. This makes the pump capable of operation in really demanding applications with maintained capacity. The new design also simplifies the service and ensures both longer lifetime and stable dewatering during the whole pump life.

Reduce cylinder block wear
Developed exclusively at IPD over 13 years ago, the original IPD Crevice Seal style liner has become one of the innovations for which IPD is renowned. Many of its customers have made this the cylinder liner of choice for their Caterpillar 3400 and now for Caterpillar C15 engine rebuilds.
Distributed locally by Metric Automotive Engineering, these liners are manufactured using high strength alloy casting and machining techniques that result in high psi breakage resistance. The liners also feature a roll burnished radius for increased flange strength and an induction hardened bore right up to the top of the liner for extended liner wear.
“Under normal circumstances, excessive vibration would result in the two lower o-rings assuming a square profile, rendering them useless as this would result in a leakage of coolant into the oil pan with potential subsequent engine damage,” Andrew Yorke, of Metric Automotive Engineering, explains.

Introduction to safety practice in South African mines

Reprinted from the machinery and materials handling section

For the purposes of this handbook, machinery is taken to mean all mechanical devices that may be found on surface or in underground mines (excluding electrical equipment and built structures, which are dealt with in other chapters).
Material handling is a term used to describe everything that is done to get people, materials and rock either into or out of a mine and is closely associated with machinery. Normally, we use machinery to do the work of material handling.

While certain types of machinery are found on all types of mines, some are only found on specific type or class of mine. In addition, because of their relative size, complexity or hazards posed to people, some machinery may be found to be isolated and fenced, while other machines operate in close contact with the general workforce. In general, large rotating machinery is kept isolated by fencing, or in enclosures such as locked buildings.

The following types of machines can be found in underground mines:
  • Winches
  • Track bound rolling stock (locomotives, hoppers and flat cars)
  • Pumps
  • Axial ventilation fans
  • Surface trucks and material handling equipment (mobile cranes)
  • Overhead cranes
  • Drilling equipment (rigs and drilling machines)
  • Movable platforms
  • Rocker shovel loaders and development equipment
  • Continuous miners
  • Shuttle cars
  • Feeder breakers
  • Rock handling systems (scrapers, boxes, tips, chutes, screens and feeders)
  • Winding equipment
  • Chairlifts
  • Mono-ropes
  • Endless rope haulages
  • Lifts and elevators
  • Crushers and mills
  • Screens, agitators, tanks and cyclones
  • Conveyor belts
  • Large rotating machines such as compressors, fans and turbines
  • Trackless mining equipment (load haul dumpers, trucks, drill rigs, utility vehicles, etc)

Surface mines may have some or all of the following equipment:
  • Surface trucks and material handling equipment such as mobile cranes
  • Pumps
  • Conveyor belts
  • Trackless mining equipment (LHDs, trucks, drill rigs, etc)
  • Drilling equipment (rigs and drilling machines)
  • Movable platforms
  • Rock handling systems (scrapers, boxes, tips, chutes, screens and feeders)
  • Draglines
  • Shovels
  • Crushers and mills
  • Screens, agitators, tanks and cyclones
  • Large rotating machines such as compressors, fans and turbines

9.2 Purpose of Machinery
All machinery used is designed for the specific purpose of making work easier for people and all types of machinery convert energy, in some way, from one form to another. In doing so, they will always produce heat and will result in some movement or other. They will also invariably store energy in a quantity that, if it is released inadvertently and uncontrollably, may result in injury to people in the vicinity. These characteristics are potentially dangerous to humans because of the size of equipment used on mines and the amount of energy involved. Generally, accidental direct contact with machinery of even the smallest type used on a mine can result in an injury or death.
The safe design and use of machinery on mines is regulated by the Mine Health and Safety Act and associated regulations. The Act requires that both the suppliers and users of a; machinery conduct risk assessments prior to use or when any change of use is contemplated, while rules pertaining to certain other types of machinery are either tightly regulated (as in the case of a winding plant), or controlled by mandatory or voluntary mine Codes of Practice.

The safe use of equipment requires that:
  • The equipment designer must ensure that the machine is properly designed for its intended use. The purpose of the machine and instructions for its safe use must be communicated to the users of the machine.
  • The users must ensure that the machine is used only as the designer intended.
  • Users must be aware that, if they modify a machine in any way or use it in any way other than its original intended application, the onus for ensuring that the modified is still safe transfers from the original designer to them. The modifications must be risk-assessed, and it is often helpful to involve the original designers in this process. Machinery such as winders, compressors, refrigeration plants, large fans and pumps, crushers and mills are normally located in secure, fenced areas, so that people who are not properly trained in their safe use and maintenance are protected.

9.3 General Hazards Posed By Machinery
In general, machines either get very hot, produce very high pressures (stored energy) or move about, offering opportunity to pinch, crush or trap an unwary bystander. Because of their size and mass, any inadvertent contact with machines poses a real and immediate danger to people.
Some machinery is stationary and other is mobile. Stationary machinery is usually protected by guarding or a separate enclosure and poses a relatively lesser danger than mobile equipment. Mobile machinery will either follow a defined path of travel (such as a train) or an undefined path of travel, such as trackless mining equipment. The latter is more difficult to automate safely.
Accidents will generally occur when people either stand in an unsafe position or when the operator of a machine cannot see them.

9.4 Avoiding Machinery Hazards
9.4.1 General Precautions

  • The following general precautions will minimize the hazards posed by machinery in mines:
  • Do not approach any machinery unless you are familiar with the dangers posed by the machinery. Before you approach, think about what might happen. What could go wrong? What could you do to protect yourself and others around you if it did?
  • Do not use any item of machinery unless you are trained to do so and have reviewed the risk assessment pertaining to the use of the machine.
  • Only use the proper tools specified for use on machinery.
  • Do not assume that any machine is safe to use unless you have personally performed pre-use checks.
  • Never work on any machinery while it is in motion.
  • Never attempt to perform adjustments on moving machinery.
  • Always apply "lockout" principles when cleaning, checking or working on machinery. This means that the person who actually works on the machine must take specific steps to ensure that no one else may either advertently or inadvertently start or cause a movement of the machine without his or her express knowledge. Be particularly mindful of isolating all possible causes of injury including electricity, pressure (air, hydraulic oil or water) and movement (sliding or falling objects), not just the ones affecting your job!
  • Never work on machinery unless it has been ‘locked-out. There is a variety of ways achieving this and each machine is different, requiring specialist training.
  • Observe how a machine moves. Identify areas or ‘pinch points’ where a hand, for example, may be trapped between two parts of a machine as they move relative to each other.
  • Always be alert to the possibility of falling objects.
  • Never get under any machine unless it is securely supported on the ground and choked (supported by an adequate block or wedge) to prevent movement. A jack is not good enough.
  • Never work behind a mobile machine parked on a slope unless it is checked.
  • Always stand in a safe place relative to machine, whether stationary or mobile. Do not assume that a driver/operator can see you and assume that any unattended machinery may start automatically.
  • Always ensure that you are clearly visible to people either working on or operating machinery. Check by speaking to them.
  • Always read signage around machine installations and operating areas and take them seriously.
  • When in proximity of mobile equipment, always assume that the operator cannot see you and stand in a position where the machine cannot reach you and does not travel as part of its normal operation.
  • Be aware of and avoid the path of movement of any machine as well as the pinch points of machines. If at all in doubt, stay away from the machine.
  • Always wear appropriate personal protective equipment when in proximity to machines. Machines that cause sparks or chips require the use of glasses and gloves in addition to full body clothing. Hot machines may require the use of thermal protective clothing. Rotating parts would indicate the use of tighter-fitting garments and the avoidance of loose equipment.
  • Be aware of certain items of machinery that may contain stored energy in specific components such as springs (mechanical energy), accumulators and pipes (pressure energy), blow-off valves and valves and radioactive sources such as weightometers. The last is distinguishable by the radiation warning sign and must not be tampered with or opened under any circumstances. Items located above the ground have potential energy. Do not release any spring, rope or chain unless the release can be achieved in a controlled manner.
  • Never loosen the bolts on a coupling, remove a hose fitting or uncouple a hose unless you    are sure the pipe is empty and that the supply cannot be switched back oh by someone else. Remember that many accidents occur simply because someone had assumed, incorrectly, that someone else had done something. Check for yourself, and check again if you have left the work site.
  • Do not work or pass below any suspended object unless it is properly supported from   below and only release such an object if it can be done in a controlled manner with proper tools and equipment.
  • Never stand in the path of a moving vehicle or in the direction in which it may travel.
  • Anticipate the runaway path of a vehicle and stand away from it.
  • Remember that an operator will seldom see below or above his normal line of sight.
  • Prevent inadvertent movement by chocking of a vehicle. Do not rely on the gears or the brakes alone. On inclines, stationary vehicles should be parked against the sidewall in a turned position (wheels turned towards the sidewall) so that they are not able to run away if the brakes or chocks fail.
Image 2: Always lockout machinery before working. Specific machines have specific lockout procedures, comply with them at all times.
Image 3: Always ensure you can be seen by operator.
