Which of the following properties are utilized in froth floatation? Correct Answer differences in physico-chemical surface properties

Feb 20, 2025

Group 1	Group 2
P. Frother	1. Alters the chemical nature of mineral surfaces so that they become hydrophobic due to action of collector
Q. Activator	2. Absorbs on air-water interface and reduces surface tension to stabilise the bubble
R. Regulator	3. Increases the selectivity of floatation by rendering certain mineral hydrophilic
S. Depressant	4. Modifies the action of collector either by intensifying or reducing its water repellant effect
