摘要：
An atmospheric leaching process for the recovery of a nickel and cobalt from a lateritic ore, said process including the steps: (a) preparing a slurry of the lateritic ore with saline or hypersaline water having a total dissolved solids (TDS) content greater than 30 g/L; (b) leaching the slurry of the lateritic ore with sulfuric acid at atmospheric pressure, (c) recovering nickel and cobalt from the resultant leachate.
