In the furnace, the concentrates are instantly oxidized, after which they melt and separate by their own reaction heat into copper matte with a grade of 65% and slag consisting of iron oxide, silica, and other compounds. Reaction in the flash smelting furnace. CuFeS 2 + SiO 2 + O 2 → Cu 2 S・FeS + 2FeO・SiO 2 + SO 2 + Reaction heat.
Copper processing begins with mining copper ore, which contains less than 1% of copper, and ends with sheets of 99.99% pure copper (cathodes). Copper mining generally takes place through open-pit mining, in which a series of stepped benches are dug deeper into the earth. Yet, it can also be mined underground, through horizontal …

Typically, 85-98% of the value of the contained metals are paid for by the smelter, bringing down the value received by the miner. Assessments for excess deleterious elements can also lower the returned value. If the metals recovered require further purification, a refining charge will also be assessed in dollars per unit of metal (typically ...
