WOA1 Process for recovery of nickel and cobalt Flotation of Nickel Copper Sulphide Ore Optimisation of
A process for the recovery of nickel and cobalt from laterite ores the process including the steps of a beneficiating the ore to separate it into a beneficiated upgraded ore fraction and a coarse siliceous low grade rejects fraction which is substantially free from fines and clay materials b separately processing the upgraded ore fraction for the recovery of nickel and cobalt and c optimum conditions for the flotation of nickel copper and cobalt from a nickel copper sulphide ore The parameters investigated include collector dosage percentage solids depressant dosage and pH The effects of these parameters at three different levels on the recovery of Ni Cu and Co were investigated using an L 9 Taguchi orthogonal array

Cobalt extraction WikipediaExtraction of nickel and cobalt from reduced limonitic
Cobalt extraction refers to the techniques used to extract cobalt from its ores and other compound or Several methods exist for the separation of cobalt from copper and nickelThey depend on the concentration of cobalt and the exact composition of the used oreFor the efficient recovery of nickel and cobalt therefore a reduced ore with a relatively high degree of reduction and low magnetite content should be obtained from the reductive roasting of limonitic laterite Download full size image

Cobalt an overview ScienceDirect TopicsNICKEL AND COBALT RECOVERY FROM MESABA
Cobalt lies between iron and nickel on the Periodic Table and its smelting behavior also falls between that of iron and nickel For example cobalt tends to oxidize more than nickel but less than iron The economic result of this observation for smelting is that the recovery of cobalt to matte is always less than the recovery of nickel to matterecovered effectively using traditional SX/EW technology recovery of nickel and cobalt from the leach solution was examined but the flow sheet was not finalized In the scope of the Mesaba project was redefined from making refined nickel and cobalt metal
