- Steam or power generation without CO2 emissions
- Sulfuric acid production
- Recovery of valuable metals such as gold, zinc, copper, and cobalt
Zinc 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 860 and 960°C. The hot gas generated in the process is used for heat recovery and is suitable for high-pressure steam production in a waste heat boiler.
