Hydrometallurgical Process - an overview | ScienceDirect Topics
2.4 Hydrometallurgy of Laterite Ores. 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 ...

Inorganic Arsenic Emissions from High-Arsenic Primary Copper ... - EPA
ASARCO-Tacoma also operates an elemental arsenic plant, independent of the copper circuit, in which purchased, refined arsenic trioxide is reduced to metallic arsenic. Offgases from the two metallic arsenic furnaces pass through condensers (one per furnace) in which the gaseous arsenic is collected as a solid and periodically removed.

Innovations: How Hydrometallurgy and the SX/EW Process Made ... - Copper
The SX/EW Process is a hydrometallurgical process since it operates at ambient temperatures and the copper is in either an aqueous environment or an organic environment during its processing until it is reduced to the metal. Because of its dependence on sulfuric acid, the SX/EW Process is at present not a substitute for, but rather an adjunct ...

Hydrometallurgical Processing - an overview | ScienceDirect Topics
Hydrometallurgical processing makes it possible to precipitate nickel on the surface of different solid materials (powder, hollow granules, particles in the form of threads, etc.). The particle size of the powder produced is determined by the size of seed powder top-charged in the autoclave and ranges from 20 to 2000 μm.

How is Cu recovered by SX-EW? - emew Corporation
An alternative to recycling the bleed is to electrowin the copper from the bleed; this low copper, high acid solution can then be sent to either the raffinate for higher leach recovery, or E1 for higher SX recovery. When using the untreated EW bleed (approximately 5 g/L copper) to leach the ore, it is less effective than a copper-free leach ...
