A method for roasting sulphide ores or ore concentrates containing precious metals is practiced in a furnace, typically in a fluidized bed. The ore and a sulphurbinding limecontaining material are supplied to a roasting furnace in which the ore is roasted with the emission of heat and sulphur dioxide. The limecontaining materialsuch as calcium hydroxideis mixed into the cooling water ...

What Is Sulphide Ore?

What Is Sulphide Ore?

+

Sulphide usually refers to CSC linkage in organic chemistry. Sulphide ore needs to be processed to extract required metals from the waste rock. Some sulphides are insoluble which makes them harmless. Examples of sulphides are sodium sulphide (Na2S), hydrogen sulphide (H2S), carbon disulphide (CS2) and tetraphosphorus decasulfide (P4S10).
