Roasting is a process in which sulphide ores are heated strongly in the presence of excess air. During roasting, the sulphide ores are oxidized, converting them into metal oxides.
Roasting is a metallurgical process used to convert sulphide ores into oxides. It involves heating the sulphide ore in the presence of excess air at elevated temperatures. The primary objective is to remove sulphur in the form of sulphur dioxide (SO₂) and leave behind the metal oxide. The reaction typically involves the oxidation of sulphide minerals:
Metal sulphide (MS) + O₂ → Metal oxide (MO) + SO₂
Roasting is a crucial step in the extraction of metals like copper, lead, and zinc from their sulphide ores, preparing them for subsequent refining processes.
