Treatment of Mixed Sulfide Oxide Ores of Copper
Many of our largest copper deposits contain both sulfide and oxidized copper minerals. The large porphyry mines, with a total copper content of from 1.3 to 2.0 per cent., send to their mills ore with an oxide content of from 0.2 to 0.4 per cent. While the recoveries of the sulfide minerals are considered satisfactory, using modern flotation ...

US Patent for Recovery of copper values from copper ores …
Copper values are efficiently recovered from a copper ore, including secondary sulfides, by first crushing the ore to a particle size P-80 of about 1 to 2 inches, then grinding the so crushed ore to a particle size P-80 of between Tyler 4 mesh and 20 mesh, and then classifying the ground ore into a fines fraction of less than 65 mesh and one or more coarse fractions of more than 65 mesh.
