Copper concentrator process

1. NONOX Autoclave: Dissolves iron and impurities from the copper minerals and replaces iron with copper. 2. FILTER: Separates solution from upgraded Super Concentrate. Solution contains dissolved iron and impurities. 3. CPL (POX) Autoclave: Dissolves copper from a small recycle. Dissolved copper is needed for NONOX. 4

To increase the copper recovery rate, often these tailings are leached with sulfuric acid. After regrinding, the rough concentrate is

Apr 11, 2017 Copper Ore Processing Methods. The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated

copper oxides have been in common use for some time. Prior to the development of the Sherritt-Gordon process for nickel and cobalt in which copper is recovered as high grade copper sulfide, copper sulfides were economically recovered in a hydrometallurgical process only during the leaching of waste dumps. .
