How to Remove Arsenic, Antimony & Bismuth from Copper

Arsenic and antimony are often present in considerable proportions in the slags from reverberatory furnaces smelting calcined ores. The conditions are different in the blast-furnace when smelting calcined ores, as the gases are of a reducing character. The larger part of the arsenates and antimonates are probably reduced to arsenides and ...

Lead, blast-furnace smelting slags - Big Chemical Encyclopedia

In lead smelting, the oxygen-enriched blast has been used in lead cupola and slag fuming furnaces. Oxygen enrichment of the copper blast furnace is also common. Limestone is widely used as a flux in the smelting of copper, lead, zinc and antimony from their ores. It is charged into the smelters with the concentrated ores.
