Copper extraction - Wikipedia

Froth flotation. Such carbonate concentrates can be treated by a solvent extraction and electrowinning (SX-EW) plant or smelted. The copper ore is crushed and ground to a size such that an acceptably high degree of liberation has occurred between the copper sulfide ore minerals and the gangue minerals.

Selectivity and power of frothers in copper ore flotation

Froth flotation is widely used for upgrading of ores and other materials. Efficiency of flotation depends on many parameters, including type, chemical structure and dose of flotation reagents. Selection of a proper frother in flotation depends on the material used, necessary dose of frother and its selectivity.
