Hydrometallurgical Process - an overview | …

Two hydrometallurgical processes for the recovery of nickel from oxide ores have been commercialized: the reduction roast–ammonium carbonate leach process and the sulfuric acid pressure leach process for the treatment of low magnesia content laterite ores. In general, smelting is applied to ores with greater than 1.7% nickel, while hydrometallurgy is used when nickel constitutes less than 1 ...

Processing of Nickel Laterite Ores on the Rise

Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores is becoming of greater necessity, with many recognizing nickel laterite ores as the future of the nickel industry.
