Cyanide process is used in the extraction of
1 \(Au\)
2 \(Ag\)
3 both \( (a)\) and \((b)\)
4 \(Cu\)
Explanation:
(c)Cyanide process is used in the extraction of both Silver and Gold because these form complex salts with \(C{N^ - }\) ion due to presence of lone pair of electron on nitrogen atom.

Cassiterite is concentrated by
1 Levigation
2 Electromagnetic separation
3 Floatation
4 Liquifaction
Explanation:
(b)Cassiterite \(Sn{O_2}\) or tinstone -an ore of tin being non-magnetic can be separated from magnetic impurities like \(Fe\) and \(Mn\) from this method.

Froth floatation process for the concentration of ores is an illustration of the practical application of
1 Adsorption
2 Absorption
3 Coagulation
4 Sedimentation
Explanation:
Froth flotation process for the concentration of sulphide ores illustrates the application of adsorption because in this process ores are adsorbed on the surface of the froth collector.

Iron ore is concentrated by
1 Froth floatation
2 Electrolysis
3 Roasting
4 Magnetic treatment
Explanation:
As Iron ore contains magnetic part \(\left( Fe _2 O _3\right)\) and non-magnetic part (gangue). Hence, Magnetic Separation is used for concentration of Iron Ore.
