Processing of Nickel Laterite Ores on the Rise

While sulfide nickel ores are processed via upgrading to concentrates and then smelting, this approach is not applicable to laterite ores. A variety of approaches are available to process nickel laterite ores, with the most prevalent approaches explained below. The method(s) chosen is dependent on the composition of the unique ore source.Ni-Co Laterites─A Deposit Model - USGS2011-9-27 · Nickel-cobalt (Ni-Co) laterite deposits are an important source of nickel (Ni). Currently, there is a decline in magmatic Ni-bearing sulfide lode deposit resources (Dalvi and others, 2004). New efforts to develop an alternative source of Ni, particularly with improved metallurgy processes, make the Ni-Co
