Sulfate leach liquors cobalt from nickel

Another process that has benefited from procedures such as that outlined above is the removal of cobalt from leach liquors derived from the extraction of nickel-bearing concentrates or mattes.406 Traditionally, the removal of cobalt from such acidic sulfate solutions has been based on the affinity of the trivalent metal ions (such as those of iron and cobalt) for hydroxide, which...
