Pyrite Roasting Plant
Pyrite roasting, most commonly known as dead roasting process and is mainly used in our zinc and pyrite roasters. When using a dead roasting process for concentrates, the sulfides are completely transformed into oxides. The gas temperature in this type of plant is typically between 800 and 900°C. The hot gas generated in the process is used for heat recovery and is suitable .
