Assertion : In froth floatation process sodium ethyl xanthate is used as collector.
Reason : Sulphide ores are water soluble.

Options

A. Statement-1 is True, Statement-2 is True, Statement-2 is a correct explantion for Statement-1.
B. Statement-1 is True, Statement-2 is True, Statement-2 is not a correct explantion for Statement-1.

D. Statement-1 is True, Statement-2 is True.

Answer

C

Explanation

Statement-1: Potassium or sodium ethyl xanthate is used as a collector. These get attached with the particles of the sulphide ore and thus make them water- repellent. Consquently the ore particles pass on into the froth. Collectors are always added in small quantity.
Statement-2: Sulphide ores are water insoluble. Therefore, (c ) Option is correct.
