Choose the correct answer from the options given below :
Show Hint
- B, D and E only
- $C , D$ and $E$ only
- $A$ and $C$ only
- B, D and C only
The Correct Option is C
Approach Solution - 1
(i) Hydraulic Washing
(ii) Froth Flotation
(iii) Magnetic Separation
(iv) Leaching
Approach Solution -2
Methods involved in concentration of ore are:
- (i) Hydraulic Washing
- (ii) Froth Flotation
- (iii) Magnetic Separation
- (iv) Leaching
Thus, Liquation and Electrolysis are NOT typically involved in the concentration of ores. These methods are not commonly used to separate or purify ores. Therefore, the correct answer is A and C only, as they are the most effective methods for concentrating ores.

What are Ores and Minerals?
Minerals are the naturally occurring, homogeneous inorganic solid substances. They are having a definite chemical composition and crystalline structure, hardness and color. For example, copper pyrite, calamine, etc.
Impurities in an ore are called gauge. The removal of a gauge from the ore is called concentration ore.
Several steps are involved in the extraction of pure metal from ores. Major steps are as follows –
- Concentration of the ore
- Isolation of the metal from its concentrated ore
- Purification of the metal
