PROCESS FOR RECOVERY OF NICKEL AND COBALT BY HEAP LEACHING OF LOW GRADE NICKEL OR COBALT CONTAINING MATERIAL |
摘要 |
<p>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) subjecting the low grade rejects fraction to a heap leach process with an acid supplemented solution to create a heap leachate for further nickel and cobalt recovery processing.</p> |
