Heavy Metal Recovery from Slags of Copper Production

2021-8-17  4 Slag cleaning by using additives The copper recovery from slag during smelting is generally related to the settling be-haviour of the matte. The settling velocity mainly depends on the size of the particles. Metallic/matte droplets with a big diameter settle very fast, smaller particles settle much slower to the ground of the bath.
