ABSTRACT:
A hydrometallurgical process for extracting nickel from comminuted nickel-bearing minerals. The process includes the steps of contacting the comminuting nickel-bearing minerals in an extraction zone with an aqueous solution having a concentration of chloride ions, metal ions and sulfuric acid at an elevated temperature and continuing the contact to form an extraction mixture slurry, including a liquid component comprising an aqueous solution containing extracted nickel and iron from the comminuted minerals dissolved therein and a solid tailings component; and, separating the liquid and solid components of the extraction mixture slurry.
