THE SEPARATION OF PYRITE AND ARSENOPYRITE BY FLOTATION

The aim of the research programme is to investigate the potential of flotation for the separation of arsenopyrite and pyrite minerals. The efficient separation of pyrite and arsenopyrite by a cheap process such as flotation has long been recognized as a desirable technological goal for ores containing both minerals.

Patent EP0568672B1 - Flotation separation of arsenopyrite ...

It is common for instance for gold in an ore containing both pyrite and arsenopyrite to be associated almost exclusively with the arsenopyrite. It is desirable in this instance to produce an arsenopyrite concentrate for gold recovery while rejecting the barren pyrite.
