Chemistry Question on General Principles and Processes of Isolation of Elements
How do we separate two sulphide ores by froth floatation method?
A
By using excess of pine oil
B
By adjusting proportion of oil to water or using depressant
C
By using collectors and froth stabilisers like xanthates
D
By using some solvent in which one of the sulphides is soluble
Answer
By adjusting proportion of oil to water or using depressant
Explanation
Solution
By using depressants or adjusting proportion of oil to water, selective prevention of one sulphide ore from coming to the froth is possible.
