The plant within the Tominskii MPE produces 28 million t of porphyry copper ore per year, where the initial content of copper in the ores is 0.4%.
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.

The process uses bacterially assisted leaching on low-grade run-of-mine ore from both the Escondida and Escondida Norte pits, with solvent extraction and electrowinning to produce the copper. Production at the plant began in 2007. In 2012, a further investment was announced in two projects at Escondida. The $3.8bn Organic …
Copper ore processing. According to the metallurgy process, the copper ore is divided into three natural types by the ratio of copper oxide and copper sulfide. That is, sulfide ore, containing less than 10% copper oxide; oxidized ore, containing more than 30% copper oxide; mixed ore, containing 10% to 30% of copper oxide.
