Roasting - an overview ScienceDirect Topics

Roasting furnaces are used to react sulfides to produce metal oxides, which can be converted to metals in the next process step. The sulfides are used as a reducing agent in nonferrous metallurgy for the recovery of metals. The process has been used for metals such as copper, lead, zinc, nickel, magnesium, tin, antimony, and titanium.

ROASTING OF SULFIDE MINERALS

ROASTING OF SULFIDE MINERALS In addition to common metals like copper, lead, zinc, and nickel a number of other metals such as antimony, bismuth, cadmium, cobalt, mercury, and molybdenum occur as sulfide minerals. Sulfides are not reduced with the most widely used redu-cing agents, carbon and hydrogen, because the free energy change for the ...

Smelting and Roasting Ores to recover gold, silver and ...

To roast sulfide ores, it takes a good red heat and a good amount of air, but not too hot as you don't want to melt them. As previously noted, materials that have been crushed to small sizes reacts better with the oxygen in the air. Don’t seal up the material, as it needs to have access to air for the oxygen to react with the sulfur. ...

2ZnS 3O 2ZnO SO2 (1)

Reduction of zinc sulfide concentrates to metallic zinc is accomplished through either electrolytic deposition from a sulfate solution or by distillation in retorts or furnaces. Both of these methods begin with the elimination of most of the sulfur in the concentrate through a roasting process, which is described below.
