copper flotation source

Froth flotation Such carbonate concentrates can be treated by a solvent extraction and electrowinning SXEW 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
