A New Application For Flotation Of Oxidized Copper Ore

2013-12-24  In this study, the flotation of oxidized copper ore obtained from Ergani CopperMining Company in Turkey was performed. This ore contains 2.03% copper, 0.15%cobalt and 3.73% sulfur. An effective processing method has not been found to recovercopper and cobalt from this ore, which has been stockpiled for 40-45 years in the idledplant. It was established that recovery of copper and cobalt from this ore withhydrometallurgical treatment is not economical, so using flotation to increase theconcentration of copper and cobalt was chosen. When flotation of the oxidized copperore was performed under standard operating conditions in the plant, good results werenot obtained. Because of this, the flotation of samples obtained from sulfurized mediumcontaining different ratios of H2S+ H2O gases was done under the same conditions.Following flotation, it was seen that copper, cobalt and sulfur present in the mediumwere concentrated. In this solution, concentration of copper

2010-8-12  Concentration A series of flotation tests was run to determine the best grind and reagent combination for treatment of the ore. Although good recoveries of copper were ob-tained by rougher flotation of ore ground to minus-48- or 65-mesh, difficulty was experienced in cleaning the rougher concentrate. Partial oxidation of the ore

RECOVERY OF COPPER FROM OXIDE COPPER ORE BY

2014-12-24  The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leaching. The ore with 4.21% copper grade used in this study was obtained from Çorum-Dangaz region of Turkey. Native copper, cuprite (Cu 2 O), tenorite (CuO), and malachite (Cu 2 (OH) 2 /CO 3) were the

Solvent extraction of Cu, Mo, V, and U from leach

2017-8-3  Vanadium extraction efficiencies were relatively low, at about 65% for flotation tailings, but in the case of copper ore reached levels of 80%. In the case of molybdenum, recovery was in the range 60–90%, but it was a higher for flotation waste.

2015-4-10  Ore Concentration by Froth Flotation. Remember that only 0.67% of the ore is copper. The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime

Rougher flotation of copper sulphide ore using

2011-11-1  Rougher flotation results for the concentration of a copper sulphide ore in a Denver cell with biosolids or a salt of humic acids as both collector and frother indicate that these materials have potential to substitute conventional chemical collectors and frothers used in the industrial flotation of sulphide minerals in Chile.

A New Application For Flotation Of Oxidized Copper Ore

2013-12-24  Following flotation, it was seen that copper, cobalt and sulfur present in the medium were concentrated. In this solution, concentration of copper and cobalt were found five times higher than normal level. Key Words: Oxidized copper ore, sulfurization, flotation, copper, cobalt, sulfur INTRODUCTION
