Solve this multiple-choice question and choose the correct option.

Mineral processing (froth flotation): Which oil is commonly used as a frothing agent/collector additive in the froth flotation process? Choose the correct option.

Difficulty: Easy

Pine oil
Castor oil
Olive oil
Coconut oil

Correct Answer: Pine oil

Explanation:

ConceptIn froth flotation, pine oil is widely used as a frother (and sometimes as part of collectors), helping stabilize froth so that hydrophobic mineral particles can be floated off.

Final AnswerPine oil
