Pyrometallurgy is the process of producing metals with the use of elevated temperatures. Due to the fast reaction rates involved small production units with high productivity can be used. Because smelting processes require high temperatures research and development activities include studies of refractory linings and constructions.

This pyrometallurgical process also helps in precious metal recovery like Au Ag Pd and some rare earth metals. The metals recovered from the heat treatment process have market value and it can be sold into the market in an easier manner and it reduces the cost for further advanced purification of metals.

The process is short and with strong adaptability and copper recovery rates can reach 95. However because sulfur escapes as waste gas and is not easy to recycle pollution can easily result. In recent years more and more pyrometallurgy methods have been developedsuch as the silver method Noranda process Japans mitsubishi process etc.

If a dead roasting process is used an oxide is formed and the subsequent operation may be a carbothermic reduction as in the case of inc and lead sulde ores. However if a partial roasting process is employed the desirable metallic mineral will still be in the form of a sulde. Pyrometallurgy 2.2 3 Carbothermic Reduction
