    Roasting (metallurgy) - Wikipedia

    Roasting is a process of heating a sulfide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation

    Leaching of sulphide ores such as ZnS, PbS etc., can be done by treating them with hot aqueous sulphuric acid. 2ZnS (s) + 2H 2 SO 4 (aq) + O 2 (g) → 2ZnSO 4 (aq) + 2S(s) + 2H 2 O. In this process the insoluble sulphide is converted into soluble sulphate and elemental sulphur. Magnetic Separation

    This method of separation is used when either the ore particles or the gangue associated with it possess magnetic properties. For example, chromite Fe(CrO 2) 2 being magnetic can be separated from the non-magnetic silicious gangue by magnetic separation.. This method is widely used for the separation of two minerals, when one of them happens to be magnetic
