Q. Froth floatation process used for the concentration of sulphide ore

Is based on the difference in wettability of different minerals

Uses sodium ethyl xanthate, $C_{2} H_{5} OC S_{2} N a$ as collector

Uses $N a CN$ as depressant in the mixture of $Z n S$ and $P b S$ when $Z n S$ forms soluble complex and $P b S$ form froth

All of the above are correct

Correct answer is (d) All of the above are correct
