Jan 15, 2020 · Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. This is accomplished through a series of several processing steps. The term copper smelting may refer to this melting step in particular or it may refer somewhat less formally to the entire process overall.

Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity. Copper can be recycled indefinitely without the base metal being compromised
These additional sources of waste water evolution are not the subject of this document and will be (or have been) discussed in detail in subsequent (or past) rationale. Slag Granulation One source of process waste water found at several primary copper smelters is slag granulation.
Copper smelting and refining facilities produce 2.5 million metric tons (MT) of smelter slag and 1.5 million MT of slag tailings per year. This is a large volume of slag, however, it is very small compared to comparable waste volumes from mining and crushing operations.

Copper in the USA: Bright Future Glorious Past Copper Producers. At the beginning of copper''s flow through the economy are the mining companies, which process vast quantities of lowgrade ore, mostly from openpit mines in order to produce copper.
The matteconverting process is normally divided into two main stages: the slagmaking stage and the coppermaking stage. In the slagmaking stage, impure scrap with a lower copper content can be used, whereas in the coppersmelting stage, pure copper scrap is used, especially spent anodes from the electrolysis process.
