Platinum Group Metals

The platinum-group metals, more commonly known as PGMs, are iridium, osmium, palladium, platinum, rhodium, and ruthenium. Platinum group metals incorporates, mining, exploration, processing, precious metals. Electric vehicles use both palladium and rhodium, as well as platinum for use in the manufacture of the catalytic converter. Platinum and palladium are used in jewelry manufacture. PGMs are usually mined in deep level, narrow reef mines, where safety is of utmost concern.

BLUEPRINT FOR BIODIVERSITY GOOD PRACTICE IN MINING

Mining companies seeking to improve their biodiversity performance can now do so with the help of a new 142- page guide that has been published by the International Council on Mining and Metals (ICMM).

ICMM’s Good Practice Guidance for Mining and Biodiversity is designed for use by mining companies at all stages of their operations, from initial exploration to mine closure planning and implementation.

PROVIDING GLOBAL TECHNICAL SOLUTIONS FOR MINERALS EXTRACTION

Outokumpu Technology’s global vision is to provide technical solutions for the profitable extraction of minerals in many countries in Africa, Australia, America, Middle East, Europe and Asia. Its mission is to contribute to the processing of metals and related materials by providing innovative solutions to the producers of concentrates of metals and to the metallurgical and minerals industries. The South African office is responsible for the sales and marketing of mineral processing equipment to the African continent.

THE EVOLUTION OF PNEUMATIC CONVEYANCE

As a specialist in pneumatic conveying together with their partner Claudius Peters, ELB Engineering Services recently launched its Fluidcon system. Pneumatic conveying has always been an acceptable means for transporting fine materials from one location to the other. From a positive point of view, the initial investment and maintenance costs are typically lower when compared to mechanical conveying systems. However, the energy consumption for the air supply on pneumatic systems is considerably higher than other options power requirements.
The Claudius Peters Fluidcon system uses the advantages of typical pneumatic conveying at considerably lower energy requirements.

]Johannesburg, South Africa --- MININGREVIEW.COM --- February 13, 2008 - Northam Platinum Limited – a mid-tier platinum company listed on the JSE – has posted its results for the first half of the 2008 financial year, reporting lower earnings per share of 199 cents compared to 280 cents in the first half of the 2007 financial year.

PROCESSING PASTE THICKENER UNDERFLOW

Particle Separation Systems Technologies (PSST) has developed and patented a new technology that can dewater paste thickener underflow, economically and effectively, to the dryness selected.

Iron ore.

The technology accepts the paste thickener underflow, which is introduced onto a woven steel belt (SBF) in a dyke and furrow shape. The paste is subsequently subjected to medium wave infrared radiation (MIR) under vacuum. The symbiosis of both negative pressure (vacuum) and MIR on the SBF provide for evaporation rates whereby 1 kWh power evaporates in excess of 2-3 l of water from a paste. The retention time decides the final paste moisture discarded from the SBF.

SOLVING A COMPLEX ORE BODY PROCESSING CHALLENGE

Fernando Monteiro, business development director of Multotec Process Equipment, says that in the case of a complex ore body, there are many variables such as viscosity and rheology that can give abnormal operating conditions.

“Test work allows for the various different factors to be included in the simulation model for the selection of equipment and the prediction of the plant performance,” he says.

AEL’S TECHNOLOGY ON SHOW

African Explosives Limited (AEL), the leading producer of explosives products, initiating systems and blasting solutions in Africa, will once again be exhibiting at Electra Mining Africa 2006 in September.

As the major supplier of explosives to the South African mining industry – and further afield in Africa – AEL has concentrated its technological innovation on developing specialised explosives, initiating systems and services that improve safety by optimising blasting efficiencies.

PROJECT IMPLEMENTATION RISKS HAVE INCREASED

These new risks are a result of the global commodities boom and economic expansion. They are a result of increased activity in the construction sector in major developing markets, including South Africa, the primary source of materials and expertise for undertaking mining projects in the region.

One such risk is the escalation in demand for commodities used in mining projects themselves and increases in prices of those commodities. For example, the recently experienced shortage of tyres for large earthmoving equipment globally was a result of the economic boom in China. The price of steel in South Africa has surged dramatically in the last two years owing to the import pricing parity formula used in South Africa, which makes its steel manufacturers among the most profitable in the world. This impacts the cost of implementing projects in the region and causes problems in managing steel price escalation.

FEWER BIG MINING RISKS IN AFRICA, BUT MORE OF THEM

These middle risks are issues such as HIV/AIDS, the lack of transport and communication infrastructure, unclear implementation of legislation, corruption, and social issues such as the presence of artisanal miners. Broadly speaking, while the investment climate in Africa’s mining sector is more favourable than in the past as a result of a better political climate coupled with better mining legislation, the new risks require more management.

“The plus side, however, is that if the management of mining companies do the right things many of these community and socially related risks can be managed,” Cattaneo says. “One can mitigate risks related to changes in regimes by forming good relationships with a variety of stakeholders including the host government, local suppliers and forming joint ventures.”
