The cobalt was recovered by ion exchange. The extraction and recovery of valuable metals, such as Mo and Co together with the alumina as Al 2 (SO 4) 3, could be achieved in this process. Recovery of V is not reported in this acid leaching study (Marafi et al., 2010).
Solvent extraction, the process of extracting a specific metal valve from a solution to concentrate and purify that metal is a multistage process involving liquid ion the first stage the metal value, in this example copper, exists in the aqueous leachate as an copper ion. The aqueous leachate is mixed with a organic solution containing a ion specific extractant.
Three different solvent extraction systems for the recovery of gold from alkaline cyanide solutions are reviewed. These include the modified amine extractants in which the basicity of simple alkyl amines, with respect to the aurocyanide anion, is controlled by the addition of alkyl phosphorous esters. The selectivity of such modified amines for gold extraction from alkaline cyanide solutions ...
