The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of Ore The ore is crushed into a fine powder and a suspension is created in water. To this are added, Collectors and Froth Stabilizers.

This is certainly the case for copper, where lowgrade ores now comprise the largest remaining deposits, particularly ores containing the mineral chalcopyrite (CuFeS 2). We know that the largest source of copper going forward is a mineral called lowgrade chalcopyrite ore and that [accounts for] something like 80% of all copper mineral value
