Removal of Copper from the Sulphide Copper Smelting Waste Slag

The applicability of chloridizing roasting for removal of copper from the sulphide copper smelting waste slag of the "Karabashmed'" copper-smelting plant is investigated. Calcium chloride CaCl2 was used as chlorination agent. It is established that the chlorinating roasting of the initial slag presented by fayalite 2FeO∙SiO2, hasn't led to noticeable removal of copper.

Copper extraction - Wikipedia

Slag is less dense than matte, so it forms a layer that floats on top of the matte. Copper can be lost from the matte in three ways: as cuprous oxide (Cu 2 O) dissolved in the slag, as sulfide copper dissolved in the slag or as tiny droplets (or prills) of matte suspended in the slag.
