Nickel / cobalt mining extraction procedures

The process begins by adding the sulfide-associated mineral to a reactor with sulfuric acid and pressurised air. This procedure removes the sulphides to obtain nickel (II) sulfate and cobalt (II) sulfate in solution. In this first dissolution stage, the sulfide is removed. NiS

Nickel: smelting, producing-Metalpedia

Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.

2010-10-1  Nickel is commonly present in two principal ore types—sulfide or laterite. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt (Co), and often precious metals such as gold (Au) or platinum (Pt), palladium (Pd) and rhodium (Rh) (the platinum group metals or PGMs) (Naldrett, 2002, Hoatson et al., 2006).

COBALT PROCESSING DEVELOPMENTS K G Fisher

2011-7-5  cobalt compared to major metals such as copper, nickel, iron and zinc; which is fortuitous since in nature cobalt occurs in relatively minor quantities in association with ores of other metals – predominantly copper, nickel and silver/arsenic. Hence cobalt is seldom mined solely in its own right and its recovery is usually viewed as a by-product.

2021-5-17  Research from Norilsk Nickel suggests that the extra cost of processing NPI to matte and then to battery grade nickel sulphate (NiSO4) will be about $5,500-$6,500/tonne of nickel (see diagram above). The main challenge for nickel sulphates is a lack of high-quality feedstock material such as intermediary nickel products – briquettes, and powders.
