Förfarande för extraktion av nickel- eller koboltvärden från en metallmalm eller ett koncentrat |
摘要 |
<p>A process for the extraction of nickel and/or cobalt values from a solution comprises the steps of effecting a cobalt solvent extraction in the presence of magnesium ions with a cobalt extractant to produce a cobalt extractant loaded with cobalt ions and a first raffinate containing nickel and magnesium ions in solution. The first raffinate is subjected to magnesium solvent extraction with a magnesium extractant to produce a magnesium extractant loaded with magnesium and cobalt ions and a second raffinate. The second raffinate is subjected to nickel solvent extraction with a nickel extractant to produce a nickel loaded extractant and a third raffinate. <IMAGE></p> |
