Principals of roasting and its types - SlideShareOct 4, 2014 . Often before roasting, the ore has already been partially purified, e.g. 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.mineral roasting process and equipment,roasting of ore - tfgRoasting of mineral ore - crusherasia.

Roasting (metallurgy) - Wikipedia

Roasting consists of thermal gas–liquid reactions, which can include oxidation, reduction, chlorination, sulfation, and pyrohydrolysis. In roasting, the ore or ore concentrate is treated with very hot air. This process is generally applied to sulfide minerals. During roasting, the sulfide is converted to an oxide, and sulfur is.
