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

2017-1-27Supergene sulfide ores rich in native copper minerals are refractory to treatment with sulfuric acid leaching on all practicable time scales and the dense metal particles do not react with froth flotation media. Typically if native copper is a minor part of a supergene profile it will not be recovered and will report to the tailings
