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
The mesh of grind size of copper minerals was determined as 75 microns after examination of ground particles under microscope. During the flotation tests the effects of type and dosage of collectors, pH, and dosage of activator Na 2 S were examined. Results of flotation tests were unsuccessful in terms of both recovery and grade of concentrate
The present invention provides a process that employs both non-selective flotation and oxidative leaching of the resulting concentrates to recover an increased amount of copper from porphyry copper ores. The non-selective flotation step uses collectors and conditions, such as pH, that are conducive to the strong flotation of sulfide minerals generally.

Mar 26, 2021 This copper flotation process is mostly suitable for treating the single sulfide ore of porphyry copper or copper-molybdenum ore. According to the distribution of copper minerals, the raw ore is grinded to -200 mesh accounting for 40-70 by the one stage grinding , and a large number of tailings are thrown away by roughing and scavenging.
flotation process. This study was carried out on the Sarcheshmeh porphyry copper sulphide ore. The Sarcheshmeh copper ore is a major porphyry copper deposit, which is located in Kerman Province in the southeastern part of Iran. 2. Experimental section 2.1. Materials The obtained samples from the ball mills input of the Sarcheshmeh copper mine were
An examination of the preceding tabulation reveals that the majority of the copper losses occur in the plus 150 mesh fractions and the minus 20 micron fraction. This loss distribution is not unusual in copper flotation. The majority of losses tend to occur in either the

First cleaner flotation concentrate will flow by gravity to the regrind cyclone feed sump. Tailing from the first cleaner flotation cells will be combined with the concentrate from the pyrite scavenger flotation section in the pyrite thickener. Copper-moly concentrate regrinding will be performed in two vertical grinding mills operated in parallel.
The design criteria were developed using the locked-cycle flotation test No. 46. The ground product is conditioned with M200 and A325 at natural pH and rougher copper concentrate floated. The rougher concentrate is reground to P80 of 21 microns and the concentrate is cleaned two to four times to produce a plus 25 Cu concentrate.
One-hundred grams of a phorphyry copper ore containing 0.6 percent copper principally as chalcopyrite was ground to minus 12 mesh. Under a flow of oxygen it was irradiated at 600 watts with 2450 megahertz radiation for 20 minutes. It was then leached for 30 minutes with acidified water to pH 1.0 at room temperature.
