Copper Plant 2

Copper chips are used to extract tellurium, which is a by-product of electrolytic copper refining, from the electrolyte in the form of cuprous telluride. Spent electrolyte is supplied to 3-stage regeneration for copper cathodes production while some sulfuric acid is recovered from the electrolyte to reduce gypsum formation and recycled in the proc-

12.3 Primary Copper Smelting

12.3 Primary Copper Smelting

(1.6 millon tons) of ore produced in 1991. Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining.

Environmental Guidelines For Nickel Smelting And Refining

ores are normally found in tropical climates where weathering will, with time, extract and deposit it in layers at varying depths below the surface. Lateritic ores are excavated using large earth moving equipment and are screened to remove boulders. Sulfidic ores, often found in conjunction with copper bearing ores, are mined from underground.

Jan 01, 2005· A copper ore has often a low copper content, 0.8-4%, and is crushed, ground and concentrated by flotation to 25-35% Cu [466, 256, 404] 1. The resulting tailings have a very low copper content (ca. 0.05% Cu), and are discarded. Dependent on ore composition, copper is produced from the ore concentrates through different routes.
