Resin-in-leach process to recover nickel and/or cobalt in ore leaching pulps

A hydrometallurgical resin-in-leach (RIL) process for directly recovering nickel and/or cobalt. Simultaneous pulp leaching by adding an acid or base, dissolves the metals of interest with adsorption of the metals rendered soluble in on ionic exchange resin. Following elution of the changed resin, pu...

More Information
Summary:A hydrometallurgical resin-in-leach (RIL) process for directly recovering nickel and/or cobalt. Simultaneous pulp leaching by adding an acid or base, dissolves the metals of interest with adsorption of the metals rendered soluble in on ionic exchange resin. Following elution of the changed resin, purification of nickel and cobalt present in the eluate can be recovered by conventional methods, such as precipitation, extraction by solvents and membranes. The regenerated resin is recirculated for further use.
