The Bureau of Mines conducted batch-scale tests on a sample of porphyry copper mill tailings as part of a study to determine the feasibility of rutile recovery from this source. The tailings that were tested contained 0.75 percent titanium dioxide tio2, with about two-thirds of the tio2 values occurring as rutile. Mineralogical studies indicated that about one-half of the tio2 content could be


Recovery Of Copper From Oxide Copper Ore By
