Question

The following flow chart represents the extraction of _______.

Froth flotation
$\downarrow$
Roasting
$\downarrow$
Smelting
$\downarrow$
Bessemerization
$\downarrow$
Electrolytic refining

• A. Copper
• B. Zinc
• C. Iron
• D. Aluminium

Answer 1

The correct option is A Copper

1) Froth floatation

For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral surfaces are naturally hydrophobic, requiring little or no addition of collector).

2) Roasting

$2CuFe{S}_2+O_2\to C{u}_{2}S+2FeS+S{O}_2$

$2C{u}_{2}S+3O_2\to 2C{u}_{2}O+2S{O}_2$

3)Smelting

$C{u}_{2}O+FeS\to C{u}_{2}S+FeO$

4) Bessemerization

$2C{u}_{2}S+3O_2\to 2C{u}_{2}O+2S{O}_2$

$2C{u}_{2}O+C{u}_{2}S\to 6Cu+S{O}_2$

5)Electrolytic Refining

In refining copper, an aqueous solution of copper(II) sulphate is electrolyzed, using impure copper as the anode and pure copper as the cathode.

So, the given flow chart is of the process of extraction of Copper.

Hence, the correct answer is $\left(A\right)$.
