Nickel and cobalt are converted to soluble sulfate salts and are recovered from the slurry in a counter current decantation circuit CCD CCD involves washing the residue and recovering soluble nickel and cobalt The remaining acid is neutralized using a limestone slurry which produces a gypsum precipitate
There are three downstream routes that have been commercialised for recovering the nickel and cobalt from the leach liquor namely mixed sulphide precipitation MSP mixed
Since cobalt is mostly recovered as by product a typical case of cobalt recovery from oxide copper cobalt ore from Kamwale deposit located in Congo is highlighted Generally such oxide copper cobalt ores are recovered by sulphidisation process In Congo the copper mineralisation is mainly composed of malachite pseudo malachite and chrysocolla
Abstract Copper and cobalt can be found on nickel laterite ores and cobalt can be found also on copper ores and many contaminants such as iron aluminum and magnesium are associated
A process for recovering nickel and cobalt values from nickel and cobalt containing laterite ores as an enriched mixed nickel and cobalt sulphide intermediate and for producing nickel and cobalt metal from the nickel and cobalt sulphide intermediate The laterite ore is leached as a slurry in a pressure acid leach containing an excess of aqueous sulphuric acid at high pressure and
This study focused on the development of hydrometallurgical process which allows the nickel Ni and cobalt Co recovery from a low grade laterite ore The developed process consists of two main stages leaching and precipitation
Laterite ore is a major primary source of nickel and cobalt production along with sulfide ore There are various processes that have been implemented for extracting nickel from laterite ore
• Nickel cobalt and other co product results pending • Pre feasibility study PFS test work program designed with samples being shipped to lab This includes over 21 years of experience in metal recovery from Laterite ore Mr Willis consents to the inclusion of the technical data in the form and context in which it appears

A part of the spent electrolyte enters the cobalt recovery circuit and is purified by the removal of iron copper nickel and zinc prior to the precipitation of cobalt as its hydroxide This is accomplished by the addition of more lime to raise the pH until the remaining copper precipitates This copper is sent back to the copper circuit
A number of synergistic solvent extraction SSX systems have been developed to recover nickel cobalt zinc and copper from sulphuric and chloride leach solutions by the solvent extraction team
There are uncommon such as Cameroon cobalt nickel manganese laterite ore the nickel are mainly concentrated in 0 In the grain size above 3mm the Philippine BNML nickel ore limonite ore nickel grade above 50mm 2 89% the coarser the grade of ore the higher the grade of nickel 3 Crushing equipment of nickel extraction
