Method for Roasting metal sulfides (Piri tas, blends, galleries, or complex sulphides chalcopyrite) with Intensive Recovery Heat

摘要

Method for Roasting metal sulfides (pyrite, chalcopyrite, blends, galleries, or sulfides complexes) with utilization of Heat released in the process.It consists in introducing the installation where the normal process of roasting, a Heat exchanger element (15) capable of working at a temperature between 400 Degrees And The atmosphere, located between the Recovery Boiler (11) and the washing Tower (19) and real gas; Hoist a pre drying of metal sulfide Roasting (1) and Air Roasting.
