Question

Which is the correct order of metallurgy for the extraction of copper metal?

• A. Concentration $\to$ smeting $\to$ bessimerisation $\to$ roasting
• B. Concentration $\to$ smelting $\to$ roasting $\to$ bessimerisation
• C. Concentration $\to$ roasting $\to$ smelting $\to$ bessimerisation
• D. Concentration $\to$ roasting $\to$ bessimerisation $\to$ smelting

Answer 1

The correct option is C Concentration $\to$ roasting $\to$ smelting $\to$ bessimerisation

The correct order of metallurgy for the extraction of copper metal is Concentration $\to$ roasting $\to$ smelting $\to$ bessimerisation $\to$ refining. Copper is extracted from copper pyrites $\left(CuFe{S}_2\right)$. Froth floatation is used for concentration of the powdered ore.
