Base Metals

The most common base metals are copper, lead,nickel, tin, aluminium, and zinc. Base metals are used in a wide variety of applications. For example, lead has proven to be a reliable source for batteries, and nickel often is used to strengthen and harden metal alloys, including stainless steel. Base metals also are used frequently to coat other metals. For example, zinc is used to coat galvanized steel.

]London, England --- MININGREVIEW.COM --- 26 September 2008 - African Eagle Resources plc – a UK-based mineral resources company exploring for and developing mineral deposits in eastern and central Africa – claims it has never been in a stronger position than it is now.

Announcing the company’s results for the six months to 30 June 2008, chairman John Park said that despite its recent share price history, African Eagle’s fundamentals had improved considerably in the past year. The two key reasons were the company’s stronger than ever assets position, and the fact that market fundamentals were more likely than not to keep metals prices above the long-term average.

HOSING FOR AFRICA

Transvaal Rubber Company (Truco) has supplied its range of rubber hosing products to a number of mining projects in Africa, both underway and recently completed. 

The company supplies rubber pulp and slurry hoses to major mining projects across Africa through turnkey contracts that typically range in value between R2 million and R8 million. It also supplies conveyor belting and five different types of rubber wear liners that can be matched to specific gravity, velocity and particle size and different processing stages.

COMMUNICATIONS CRITICAL FOR MINING INDUSTRY

Africa’s mining industry often operates in underdeveloped and remote areas. Standard telecommunications networks are most of the time unavailable or, when they exist, unreliable. Most operators have no other choice than to implement a satellite based solution to overcome local network hurdles. Selecting the appropriate solution is nevertheless a complex thing to do, as there are multiple offers on the market, ranging from mobile to fixed, and from shared low cost to dedicated high end, solutions. Several questions need to be considered prior to choosing a solution, such as: do I need a short term or long term solution? Do I need mobility? Which applications do I need to run? How sensitive are they to latency? How much bandwidth do I need to run several applications concurrently without degrading the service? Do I need carrier grade quality voice? Will I run video-conferencing type applications? What level of redundancy do I need? How much will downtime cost me? How easily up-gradable does my system need to be? How much will it cost to upgrade?

The answers to these questions often lead mining industry corporate IT managers to deploy dedicated C-Band VSAT based solutions for medium to long term requirements during the mine construction and production phases; especially if their company is operating in environments affected by heavy rains or sandstorms. Customers looking for a dedicated, always-on and reliable turnkey solution integrating Voice, Data, Internet and Multimedia services will choose a high speed dedicated DVB/SCPC (Digital Video Broadcasting/Single Carrier per Channel) or SCPC/SCPC VSAT solution. The network architecture for each of these solutions will depend on each customer’s requirements and budget.

IMPROVING MINE VENTILATION ELECTRICITY CONSUMPTION

STEVEN
Steven Bluhm.
Mine ventilation can account for 30% to 40% of some deep underground mines’ total electricity consumption. Taking that into account, a variety of energy management options offer significant scope for improving mines’ electricity consumption profiles.

Traditionally these mines have been ventilated and cooled on the basis of all-the-mine all-the-time. Although there have been recent improvements in this approach, significant potential remains for further improvement and mine ventilation engineers have developed an appetite for exploiting safe opportunities.

EXPLOSIVES IN WEST AFRICA

Explosives company BME, a subsidiary of Omnia Holdings Limited, has been active in West Africa for the past decade. After the south and southern African region that region is the continent’s biggest focal point for new mining projects, based on BME’s internal assessments.

Ralf Hennecke, BME general manager of international marketing notes that for many, West Africa is seen as a difficult place to do business. “It is just a bit more extreme than other places. The climate, the dust, the heat, the remoteness. And, in particular, West Africa is logistically challenging.

]Dakar, Senegal --- MININGREVIEW.COM --- 26 September 2008 - The government of the West African state of Guinea wants more talks with Rio Tinto – the London and New York-listed international mining group headquartered in the United Kingdom, and the world’s third-largest mining company – about its key Simandou iron ore project in Guinea. The US$6 billion (R48 billion) project is crucial to Rio's future production portfolio as it fights off a hostile takeover bid from rival miner BHP Billiton.
