lthough nickel mining in Britain has been limited to a few small deposits, exploration has been carried out in several areas since the nickel boom of the late 1960s. The search for the platinum-group elements (PGE)* began in the 1980s, in response to increased industrial demand and long-term supply uncertainties. Exploration has identified a

Niobium and tantalum are commonly found in the minerals pyrochlore and columbite. Cobalt is mined specifically from ores like cobaltite, but also as a byproduct of copper and nickel mining (Raymond, 1995). Lithium is found in three main types of deposits: brines, pegmatites, and sediments.
The nickel sulphide deposit at Trojan Mine occurs within a pile of ultramafic lavas subjected to a lower amphibolite grade of metamorphism and are characterised by lensoidal bodies of serpentinite. The lavas form part of the Upper Greenstones (Bulawayan Group) of the Mazowe greenstone belt.
Where are the world's top nickel deposits located? As some of you may know, 65 percent of nickel used in the Western World is used to produce stainless steel. There's money to be made in the silvery-white metal as it plays a significant role in the preparation of alloys.
Nickel mining in New Caledonia is a major sector of the New Caledonian economy. The islands contain about 7,100,000 tonnes of nickel which is about 10% of the world's nickel reserves. With the annual production of about 107,000 tonnes in 2009, New Caledonia was the world's fifth largest producer after Russia (266,000), Indonesia (189,000), Canada (181,000) and Australia (167,000).
In 1999 proven+probable reserves were more than 35 million tonnes at 2.3% Ni using a 1.5% Ni cut-off, and up to 60 mt at a 1% Ni cutoff. As such it is one of the highest grade lateritic nickel deposits in the world. The mine and ferro-nickel plant are operated by Cerro Matoso S.A., a subsidiary of the Billiton group. Return to top
