Heating ores to elevated temperatures is called roasting, and it causes the oxygen in the air to convert the sulfur in the ore to sulfur dioxide, which is a gas and is emitted to the air. The process works best when the ore is crushed to small pieces before roasting.

Roasting. It is a process that is applicable for sulphide ore which subjects to the heat and air. In roasting, the sulphide ore is heated at the temperature below the melting point. For example Leaching. It is a chemical method in which the ore is treated with the suitable reagent to solubilize the ore.
