Why is froth floatation method used for concentration of

Jun 02, 2019· Only sulphide ores are concentrated by froth flotation process because pine oil selectively wets the sulphide ore and hence brings it to the froth. This method is usedfor that metals whose ore gets preferably wetted by the oil and the gangue by the water.

Why is it only sulphide ores are concentrated by froth

Froth floatation works by formation of froth which contains the ore, while the gangue remains in water. For this the oil (pine oil) used to make the froth should only have an affinity to the ore and not to the gangue. Sulphide ores have that property. Which means the pine oil wets the Sulphide ore
