Lead smelting - Wikipedia

Dross refers to the lead oxides, copper, antimony and other elements that float to the top of the lead. Dross is usually skimmed off and sent to a dross furnace to recover the non-lead components which are sold to other metal manufacturers. The Parkes process is used to separate silver or gold from lead.

Gold Smelting & Refining Process

In the smelting process, borax helps to reduce the gold smelting point of the charge and capture metallic oxides. The addition of this reagent must be controlled; otherwise the slag will be extremely hard and non-homogeneous.

Antimony smelting process generating solid wastes and dust ...

A large amount of solid waste has been produced by the antimony smelting process in the “World Capital of Antimony”, Xikuangshan area in China. This study comprehensively investigated the physical and stone characteristics of the various solid wastes, as well as the leaching behavior of the solid wastes, which included water-quenched slag, arsenic-alkali residue, desulfurized slag and blast furnace dust.
