Abstract Copper and cobalt recovery from a copper–cobalt ore of Democratic Republic of Congo (DRC) by ammonium chloride roasting is studied. The effects of roasting temperature, roasting time, and the dosage of ammonium chloride on the leaching rate of copper and cobalt are investigated. The results show 90% copper and 95% cobalt recovery under the optimal

Recovery Of Cobalt From Copper Ore. Sep 29 2017 In terms of impurities manganese is the most troublesome impurity for cobalt recovery specifically from copper-cobalt ores in which Mn is present in high quantities. AirSO 2 or O 2 SO 2 mixtures are used to oxidize and precipitate manganese from sulfates commercially adopted at DRC copper-cobalt plants Tenke

By treatment with hot water, recovery of copper and cobalt from the ore mixture was aimed selectively. 2. Experiment 2.1 Sample Preparation The slag sample used in this investigation is a composite from different levels of the copper slag obtained from Kastamonu Kure region, the chemical composition of which is given. A mineralogical study by Arslan, C. [12] showed that

Significant amounts of cobalt, a strategic and critical metal, are present in readily accessible copper recycling leach solutions. However, cost-effective technology is not available to separate and recover the cobalt from this low-grade domestic source. The Bureau of Mines has developed a procedure using a chelating ion-exchange resin from Dow Chemical Co. to successfully

This technology is applicable to the recovery of nickel, cobalt, copper, and platinum group metals from furnace or converter slags emanating from copper or nickel smelters treating sulphide concentrates. Pilot-plant testwork at Mintek has demonstrated recoveries of 98% for nickel and over 80% for cobalt, at power levels of up to 600 kW. Results of computer

The recovery of copper and cobalt from the oxidized ore using fungal metabolic acid was found to be highly dependent on the amenability of the ore

30/05/2019· The results of ore leaching with sulfuric acid showed that the degree of recovery of cobalt increased from 7.3 to 35.2% with an increase in the H 2 SO 4 concentration from 0.5 to 2 N.
