Get Latest PriceA hydrometallurgical process for the recovery of nickel and cobalt values from a sulfidic flotation concentrate the process involves forming a slurry of the sulfidic flotation concentrate in an acid solution and subjecting the slurried flotation concentrate to a chlorine leach at atmospheric pressure followed by an oxidative pressure leach
Processes of grinding conditioning and flotation were studied individually and in con cert and a series of continuous tests were run based on the parameters developed to obtain engineering data for subsequent economic analysis overall cobalt grades of 300 wt pct at a recovery of 640 pct were achieved metallurgist research chemist
That means that the copperbearing particles are initially recovered followed by carrollite in later stages of the flotation process for cobalt the maximum final grade was observed for sample s9 with 130 co and a cobalt recovery of 665 while the highest final recovery was observed for sample s8 with 744 cobalt recovery and a final
The copper flotation step is inherently inefficient for cobalt with recoveries typically from 40 for oxides up to 80 for sulphides so there is a substantial amount of cobalt contained in tailings dams that could be recovered eg the kolwezi tailings project
The ancient flotation tailings from lefke cyprus have a potential for nonferrous metals such as cobalt and copper from more than 95 million tons of reserves containing 038 cu 0032 co and 226 fe recovery of cobalt and copper from these tailings can provide great benefits from economic and environmental perspectives
Recovery of copper from slow cooled ausmelt furnace ausmelt furnace slag contains about 09 cu mass with increasing the amount of ausmelt furnace slag the recovery of copper from it will produce an enormous economic yield the recovery of copper by floatation from slow cooled ausmelt furnace slag was studied in this paper
Cobalt and nickelarsenates can be floated with either 1nitroso2napthol or tertiary butyl1nitroso2naphthol which also is often applied to tungstite ores such as tungsten trioxide wo3
Flotation treatment of the gravity tailing recovers additional silver values for marketing at a separate smelter the silver cobalt extraction flowsheet in this study the silver occurs essentially as impure native silver together with argentite cobaltite and other complex sulfides represent approximately 65 of the total silver recovery
The ancient flotation tailings from lefke cyprus have a potential for nonferrous metals such as cobalt and copper from more than 95 million tons of reserves containing 038 cu 0032 co and 226 fe recovery of cobalt and copper from these tailings can provide great benefits from economic and environmental perspectives
A review of why new technologies are going to drive the future of cobalt recovery and production background of cobalt cobalt the element that is just starting to create a lot of buzz from the auto industry to electronics production the popularity of cobalt is growing rapidly chiefly for its use in rechargeable global demand for cobalt increases current sources of cobalt
Abstract in this study recovery of cobalt from a copper flotation tailing pyrite concentrate by oxidative acid leaching was investigated the asreceived tailings d80 64 m contained 6407
Improvements of cobalt recovery in flotation of cuprocobaltiferrous ore at gecamines in proceedings of the copper cobalt nickel and zinc recovery conference the sa inst min metall zimbabwe july 2001 google scholar soto and laskowski 1973
The viability of bulk sulphide flotation was demonstrated which in turn allowed concentration of the pay metals cobalt bismuth and gold further refinements to the flotation flowsheet allowed for establishment of the conditions for selective recovery of cobalt and bismuth into their respective sulphidic concentrates under robust reproducible
The tailings can contain as much as 45 pct of the cobalt originally present in the lead ore researchers at the bureau of mines rolla research center used froth flotation to recover up to 65 wt pct of the cobalt and from 60 to 90 wt pct of the other valuable metals such as ag cu pb and zn from the mill tailings
Flotation of oxide copper and copper cobalt ores 191 introduction flotation practice of oxide copper minerals dates back to almost 60 years ago and has been applied in central africa congo by union miniere belgium the process involves two basic flotation methods a fatty acid flotation of oxide copper minerals from siliceous ore

Test work indicated that the recovery of copper and cobalt in the flotation process would be in the order of 55 to 65 for copper and 40 to 50 for cobalt get price effect of grinding time on flotation recovery of copper smelting slags
Processing gold ore by flotation gold recovery by flotation a test on a sample crushed to pass a screen of 120 holes per linear inch containing 37 gold and 48 copper gave a recovery by flotation alone of 90 of the gold and 985 of the copper but left 8 gold in the tailing
The recovery of cobalt by flotation is typically poor usually below 60 and in many instances it is well below this value the sulphide and oxide flotation circuit at konkola copper mines kcm is shown in fig 10 the plant is a twostage circuit consisting of a sulphide flotation section and an oxide flotation
