摘要: A heap leach process for the recovery of nickel and cobalt from a lateritic ore, said process including the steps of leaching and/or agglomerating the ore with a lixiviant that includes ferrous ions, wherein the lixiviant is able to liberate cobalt from the cobalt containing minerals within the ore in preference to nickel, to produce a cobalt rich pregnant leach solution relatively free of nickel.

摘要: A process for the treatment of a solution containing at least ferric ions, and one or more metal values, said process including the step of maintaining a controlled concentration of ferric ions in solution for a sufficient residence time to control iron hydroxide or oxide crystal growth, and precipitating the iron as a relatively crystalline iron hydroxide or oxide while minimising the loss of the ore or more metal values with the iron hydroxide or oxide.

摘要: A process for the recovery of nickel and cobalt from a nickeliferous oxidic ore by heap leaching, the process including the steps of: a) forming the nickeliferous oxidic ore into one or more heaps; b) leaching the ore heap with a leach solution in a leach step wherein the leach solution includes an acid supplemented hypersaline water as the lixiviant, the hypersaline water having a total dissolved solids concentration greater than 30 g/l; and c) recovering the nickel and cobalt from the resultant heap leachate.
