The ore that is concentrated by froth floatation process is

A

Cinnabar

B

Bauxite

C

Malachite

D

Zincite

Text Solution

Verified by Experts

The correct Answer is:
A
Froth floation is used for the concentration of sulphide ores only. Thus, cinnabar, i.e. HgS is concentrated by this method. Bauxite `(Al_(2)O_(3).2H_(2)O)`, maalachite (`CuCO_(3).CU(OH)_(2))` and zincite `(ZnCO_(3))` cannot be concentrated by this method.
