ALTA MetBytes - Developments in Hydromet Processing

2020-1-15 · The DNi process is being developed by Direct Nickel Limited, Australia, for the processing of both limonite and saprolite ores. It is an atmospheric nitric acid leaching process coupled with a patented acid regeneration system. Nickel and cobalt extractions are high (reported to be > 90%). No secondary neutralization is needed to remove residual iron. Nickel and cobalt are recovered as MHP or further processed to mixed oxide. Iron and magnesium oxides are possible by-products. The flowsheet is a closed loop in that there are no liquid effluents and solids are environmentally benign. The process has been demonstrated at a continuous integrated pilot plant level. Direct Nickel Projects Pty Ltd, the owner of the Direct Nickel Process, is now under new ownership and management. The company is actively pursuing opportunities to license the Direct Nickel Process to companies wishing to adopt a simple but elegant solution to the production of either a mixed hydroxide, a mixed oxide product or, indeed, nickel metal. The new owners are focussed on achieving the first commercial utilization of the Process
