flotation of cobaltite

Danafloat
Various cobalt bearing minerals have economic significance including cobaltite (CoAsS). carrollite (Cu(Co.Ni)2S4), and linnaeite (Co3S4). These are often associated with copper minerals and pyrite and pyrrhotite iron sulphides. Two different flotation separation strategies are used.

Separation of cobaltite - CALIFORNIA RESEARCH CORP
The separation of the group cobaltite-pyrite-pyrrhotite from both the gangue and the chalcopyrite is easy and straightforward. The gangue can be separated by floating the minerals in an acid or neutral circuit, employing the usual flotation agents for flotation of sulfide minerals, whereby the cobaltite-pyritepyrrhotite are floated and the ...
