For which of the following ores froth floatation method is used for concentration?
Updated On: Jul 6, 2022
- Haematite
- Zinc blende
- Magnetite
- Carnallite
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Froth floatation method is used for removing gangue from sulphide ores. In this process, a suspension of the powdered ore is made with water Among the given options Zinc blend (ZnS) is the only sulphide ore and hence Froth floatation process is used for its concentration.

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
