Treatment of Mixed Sulfide Oxide Ores of Copper
On many of the porphyry ores, the recovery of oxide copper by this method would be very small; or, if some way were found to float the silicate copper, the grade of concentrate would be lowered to a point where smelting costs would be prohibitive. From most of these ores, the oxide copper must apparently be dissolved by some solvent.
