This article compiles the results of a review of world copper solvent extraction (SX) plant practices and examines changes in operating practices in the last seven years as compared to previous world copper SX surveys in 1996 and 1999. Trends covered

Platinum-group element concentrates are made into a matte that is low in iron, low in sulfur, and enriched in platinum-group elements by smelting and converting. Smelting removes most gangue minerals as molten slag. Converting removes most iron and s

Electrowinning produces high-purity nickel metal by electrodepositing nickel from purified leaching solutions. Chloride and sulfate electrolytes are used. It is mostly used to recover nickel from the solutions produced by leaching sulfide mattes and

The converter matte contains nickel, iron, and sulfur. It may also contain copper, cobalt, silver, gold, and platinum-group elements to a greater or lesser extent. These elements are ultimately separated and made into metal either hydrometallurgicall

Nickel imparts corrosion resistance, workability, high-temperature strength, and attractiveness to most of its applications. It is mainly used in alloys, especially stainless steel. Nickel is produced from laterite and sulfide ores. Laterite ores are

About half the global production of primary cobalt is from nickel laterite and sulfide ores. Most of this cobalt is produced by the leaching of laterites and the smelting of sulfide concentrates. Both these processes produce an intermediate sulfide t

South African platinum ores contain platinum-group elements either as discrete mineral grains, for example, braggite, (Pt,Pd)S, or in solid solution in pentlandite, (Ni,Fe) 9 S 8 . As-mined ores, delivered to a concentrator, typically contain 3 or 4

In the nickel industry, converting is the production of a low-iron matte, containing 0.5%-4% Fe, from a furnace matte that contains between 20% and 40% Fe. The iron in the furnace matte is most often removed from the matte into the slag by oxidation

About half of the global mine production of cobalt comes from the layered sedimentary cobalt-copper ore deposits of central Africa. The deposits usually consist of a weathered surface cap over unweathered sulfide ore below. The host rock is usually s
