Concentrating Nickel from Leaching Solutions for Oxidized Nickel Ore Based on Precipitation of Hydrates

Mineral Dressing

Abstract

The article focuses on concentrating of nickel from lean solutions of leaching of oxidized nickel ore. The proposed block diagram of process flow chart for such solutions includes hydrolytic removal of admixed iron and aluminium and precipitation of nickel concentrate by calcinated magnesia. As a result, nickel content of the concentrate is 26–26% at the recovery of 95–97%. The issues of decontamination and recycling of the solutions are solved.
