Abstract

Procedure for roasting pyrites in a counter-current rotary kiln, characterized in that the pyrite is first roasted in the rotary kiln in the absence of oxygen, to iron oxide and a mixture of sulfur dioxide and sulfur, the sulfur contained in the roasting gas is burned in a subsequently connected combustion chamber with steam extraction and the test gas is then separated from the solid impurities and in the form of steam.
