The nickel content in such sulRde ores is generally low (}3%) and varies from place to place in the same deposit. The low nickel content of the presentday nickel sulRde ores renders them unsuitable for either direct smelting or hydrometallurgical extraction, thus requiring beneRciation. The usual method of nickel extraction from sulRde

It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media. Our ball mills are the most robust design in the industry, available with either geared or gearless drive arrangements.
