The process routes of primary copper production . The primary smelter and reﬁnery plant uses concentrate as a raw material, produces copper cathodes, sulphuric acid, and precious metals, and discards slag and offgases.
The process includes three operations similar to copper and nickel slag production: (1) roasting, (2) smelting, and (3) converting. Lead and zinc are often related as coproducts in both source and metallurgical treatments, and the various combinations of slags, which include lead, lead-zinc, and zinc, are similarly produced.
Copper production About 80 % of primary copper production comes from low-grade or poor sulfide ores. After ... However, a typical disadvantage is the high copper content of the slags, and the relatively high flue dust content in the off-gas, which can cause problem in the waste-heat boiler.
Abstract An important cause for the mechanical entrainment of copper droplets in slags during primary and secondary copper production is their interaction with solid spinel particles, hindering the sedimentation of the copper droplets.

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.

Copper recycling may also include copper recovery from process residues such as slag, dust and sludges. Often these types of copper-containing residues are internally recycled within the plant. However, there is a need for bleeding and thus an outlet from the plant.
For example, converter slags are a byproduct of nickel and copper production, and anode slime is a byproduct of copper refining. Reduction slag may be the major product of a production process in which an extracted metal is concentrated, for example, titanium and vanadium slag.
