The Kevitsa flotation feed size is not particularly fine for a complex sulphide separation process, but the nickel sulphide losses are overwhelmingly fine, with more than 80% of nickel in tail <25 μm. The <25 μm copper in tail is only about half as much as the <25 μm nickel in tail. Therefore, at Kevitsa improving nickel recovery must focus ...
