  • Nickel processing

    The New Caledonian deposits are of the garnierite type, and numerous other laterite deposits are scattered around the world, presenting a wide range of mining, transport, and recovery problems. The nickel content of laterites varies widely: at Le Nickel in New Caledonia, for example, the ore delivered to the smelter in 1900 contained 9 percent nickel; currently it contains 1 to 3 percent.
