    Principals of roasting and its types

    Often before roasting, the ore has already been partially purified, by froth floatation. The concentrate is mixed with other materials to facilitate the process. This process is generally applied to sulphide minerals. During roasting, the sulfide is converted to an oxide, and sulfur is released as sulfur dioxide, a gas. 5.
