Process for recovery of nickel and Cobalt by Heap Leach, a material containing low grade Nickel or Cobalt

摘要

A process for the Recovery of nickel and Cobalt from laterite ores, the process including the steps of: a) the benefit for Separating mineral ore grade in a fraction of a fraction of Waste and improved from low grade, siliceous, thickWhich is substantially free of fines and Clay Materials Processing separately; (b) The fraction of ore Grade improved for the Recovery of nickel and Coba and (c) subjecting the waste fraction of low degree to a Heap Leaching process with an additional Solution Tada with acid leaching to create a stack for further processing for recovery of nickel and CObalto.
