Vedclass · Answer

(B) In the froth flotation process,collectors like pine oil,fatty acids,and xanthates are added to the suspension of powdered ore in water to make the mineral particles preferentially wetted by oil. Froth stabilizers like cresols and aniline are added to stabilize the froth. Therefore,the statement that aniline is a froth stabilizer is correct. Zincite $(ZnO)$ is an oxide ore,not a carbonate ore. Titanium is refined using the Van Arkel method,not zone refining. Sodium cyanide $(NaCN)$ is used in the leaching process for the extraction of silver.
