Chalcopyrite cu Sphalerite zn Separation By Flotation
Apr 14, copper recovery was between 70-75% on this difficult ore. by lowering the copper grade and increasing recovery the zinc content would become excessive. the smelter did not permit copper with over 10% zn. flotation machines “sub-a” flotation cells of the cell to cell type are recommended for all the flotation steps in this treatment.Apr 19, extraction of copper from suitable ore by leaching methods is generally assumed to cost less than the combined expense of concentration, smelting, and refining, and experimental data tend to confirm this opinion. at the butte-duluth plant, which is handling in excess of 100 tons of oxidized ore daily, the copper is said to cost $0.085 per.
