Abstract
The process according to the invention relates to the treatment of iron-containing sulfides, such as pyrites or pyrrotites, for producing sulfuric acid or elemental sulfur and storable slag. According to the process, finely divided pyrites concentrates or pyrrotites concentrate, or finely divided pyrites or pyrrotites ore, is oxidised with oxygen-enriched air in a flame smelting furnace, such that a sulfur dioxide-containing gas, having an SO2 content of at least 25%, and slag are obtained as the product. The method according to the invention can also be used for treating calcination products.
