mineral roasting process and equipment

Roasting (metallurgy) - Wikipedia

Roasting is a process of heating a sulphide ore to a high temperature in presence of air. It is a step of the processing of certain ores. More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated

Roasting - an overview ScienceDirect Topics

In oxidation roasting, the sulfide ore is first decomposed into low-valence sulfide and sulfur, and then the oxide is formed. The oxidation roasting of some sulfide ores is exothermic. Oxidation roasting equipment includes a rotary kiln, a multichamber baking furnace, and fluidized baking furnace (see fluidized roasting).
