The roaster complex has an integrated effluent plant which removes the As content from the process water. Effluent is treated using calcium arsenite precipitation. "Blending is the most common solution to the problem of treating high-As content in copper concentrates, where high-As concentrate is mixed with clean copper concentrate to dilute

Modified Zincex Process by Técnicas Reunidas The SX unit yields an extremely pure electrolyte free of impurities like Co, Ni, Cu, Cd, Mn, Fe, Mg, Ca, Na, K, Cl, F, etc. This permits the recovery of zinc from secondaries (high Cl and F) or high-Mn concentrates without limitation. In addition Minor metals such as Cadmium, Copper,

This process recovers copper from chalcocite-pyrite ores or concentrates by low-temperature pressure leaching, copper SX–EW. The plant has operated at up to 50,000 tpa Cu production at a cash cost (US$) of as low as $0.31/lb of copper from mining through to metal production ( Dreisinger et al ., 2002b ).

The bioleaching process can be fully integrated with downstream metals recovery processes. For example, solvent extraction and electrowinning (SX-EW) can be applied to produce LME A-grade copper cathode, and precipitation processes can be employed to produce metal intermediates (such as hydroxides, carbonates or sulfides).

Solvent extraction in the primary and secondary processing of zinc subject of investigation for some time. Interestingly, however, the first commercial application of zinc SX on the mainstream process liquor will be for the exploitation of an oxide orebody. Sulphide ores and concentrates Most zinc ores occur as sulphides and, as such, are amenable

SX is a liquid-liquid process and a standard method used for separation and purification of elements and compounds in concentrates. Some metals, such as REEs, are more difficult to separate. In such cases, the extract, scrub and strip unit operations of an SX circuit will contain multiple individual processing steps – typically mixer-settler
