What Is Copper Smelting? (with pictures) - InfoBloom

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

Copper Smelting - 911 Metallurgist

2021-1-13  The predominant copper process is reverberatory furnace smelting of sulfide concentrates to produce matte and slag, followed by treatment of the matte in converters to form blister copper. The offgases from the reverberatory furnace are usually not more than 2 percent SO2, and of varying SO2 content from the converters, precluding economic sulfur recovery in most cases.
