How clean can the nickel industry become? | McKinsey

Sulfide orebodies usually extend in depth but with a limited footprint. The produced concentrates need to be smelted in a process emitting SO 2-rich gases, and the refining of smelted products is usually performed by leaching with sulfuric or hydrochloric acid, which can have potential emissions of arsenic, fluorine, and chlorine.In contrast, laterite …

A life cycle assessment of a new laterite processing technology

The most abundant sources of naturally occurring nickel are nickel laterites and nickel sulphides. About 60% of nickel ore is found in the form of laterite deposits and the remaining 40% are sulphides (Jessup and Mudd, 2008). Laterites are usually formed near the surface by the weathering of ultramafics which are iron and magnesium rich rocks.

Lateritic nickel ore deposits - Wikipedia

Nickel laterites are generally mined via open cut mining methods. Nickel is extracted from the ore by a variety of process routes. Hydrometallurgical processes include high-pressure acid leach (HPAL) and heap leach, both of which are generally followed by solvent extraction - electrowinning ( SX-EW) for recovery of nickel.
