Chloride assisted hydrometallurgical extraction of metal |
| abstract |
A halide assisted hydrometallurgical process for the extraction of nickel from a nickel laterite ore with negligible copper and substantial magnesium, comprises subjecting the nickel laterite ore with negligible copper and substantial magnesium to pressure leaching at a temperature of about 225 C, in the presence of oxygen and an acidic solution having about 100 g/L to about 200 g/L free acid. The solution contains chloride ions at a concentration in the range of about 8 g/L to about 20 g/L and a source of bisulphate or sulphate ions to form a product solution of the nickel. The source of bisulphate or sulphate ions is at least one number selected from the group consisting of sulphuric acid and a metal sulphate that hydrolyzes in the acidic solution at the elevated temperature of the pressure leach. At least some of the magnesium is removed from the product solution and at least some of the nickel is removed from the product solution. |
