Copper Smelting Process - Furnaces Used, By-Products, and ...

The copper ore become molten copper droplets that fall to the bottom of the furnace forming a molten copper layer with a slag floating on top of it. The molten copper is tapped and sent through the same processes as the reverb smelted copper, except for the converter stage, as it has been already converted to blister copper in the flash furnace.

Copper Scrap - an overview | ScienceDirect Topics

Slag fuming is a well-established process that has been in industrial operation for more than 80 years. Slag fuming is traditionally used to vaporize zinc from zinc-containing slags, mainly lead blast furnace slag, but also is applied in a few plants for copper-smelting slag. Reduction is achieved by using pulverized coal, lump coal or natural gas.
