Roasting (metallurgy)
Roasting is a process in Metallurgy that involves the thermal treatment of minerals to produce a chemical reaction, typically to facilitate the extraction of Metals. This process is often used to convert sulfide Minerals into oxides, which can then be reduced to produce the desired metal. Roasting can be performed using a variety of techniques, including rotating furnaces and Fluidized bed reactors. The process requires careful control of Temperature and Atmosphere to achieve the desired chemical reaction. Roasting is an important step in the production of many metals, including Copper, Zinc, and Lead.
