- ABoth Statement I and Statement II are true
- Correct answerBStatement I is false but Statement II is true
- CStatement I is true but Statement II is false
- DBoth Statement I and Statement II are false
Solution
The rotating paddle in the froth flotation process violently agitates the suspension of powdered ore in water, as well as the collectors and froth stabilisers, generating frothing. Iron pyrites are generally avoided for extraction of iron due to environmental reasons.
Hence, the correct answer is option: 'B'.
