Question

Describe the verious method used for obtaing metal from the roasted ore.

Answer 1

Explanation:

Question: Describe the various methods used For obtaining metal from the roasted ore.

Answer:

Roasting :

Roasting is a process of heating of sulphide ore to a high temperature in presence of air.

Methods Of Extraction

Oxidation Roasting :

Oxidative roasting is the process of converting metallic compounds in waste materials into oxides using oxidants. The aim is to obtain oxides to facilitate the next step of smelting. Oxidation roasting is often used in sulfide ore smelting.

Salt Roasting :

Sulfuric acid roasting and chlorination roasting are typical examples of salt roasting. The aim is to convert as many metallic sulfides or oxides in the material into soluble salts dissolved in water, or dilute acids, under controlled conditions.

Reduction Roasting :

Reduction roasting refers to the roasting process of reducing metal oxides to metal or low-valence compounds in a reducing atmosphere. The reductant can be used in a solid, liquid, or gas, such as a carbon-reduction agent.
