Question

The role of depressants in Froth Flotation method* is to (A) selectively prevent one component of the ore from coming to the froth. (B) reduce the consumption of oil for froth formation. (C) stabilize the froth. (D) enhance non-wettability of the mineral particles.

Depressant prevent one component from coming to the froth. For eg., in Galena ore, the depressant (NaCN) prevents impurity (ZnS) from coming to the froth.

Q. The role of depressants in Froth Flotation method* is to

selectively prevent one component of the ore from coming to the froth.

reduce the consumption of oil for froth formation.

stabilize the froth.

enhance non-wettability of the mineral particles.

Depressant prevent one component from coming to the froth.
For eg., in Galena ore, the depressant $(N a CN)$ prevents impurity $(Z n S)$ from coming to the froth.
