Asserton : Ethyl xantyhate is used as a collector in froth floatation process.
Reason : Collectors depress the loatation property of one of the componenets of the ore and thus help in the separation of different minerals present in the same ore.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
C
Assertion is true but reason is false. Collectors absorbs themselves on polar groups to grains of ores and thus derive them on the surface to pass on into the froth
