Selective chalcopyrite flotation from pyrite with

The flotation of pyrite was depressed strongly by SGX while the floatability of chalcopyrite only slightly reduced at the pH range 710, and the optimal differential flotation chalcopyrite from pyrite was achieved at weakly alkaline pH range, with SBX as collector.


Flotation of Pyrite Metallurgist Mineral Processing

Sodium hydroxide and sodium sulfide gave, in most cases, a distinct separation of sphalerite from chalcopyrite; i.e., a high copper and low zinc by suppressing the flotation of sphalerite. Tarnish on the Mountain copper pyrite tended to prevent flotation.


The separation of chalcopyrite and chalcocite from pyrite

After mixing with pyrite, chalcocite flotation was slightly lower than chalcopyrite flotation, while pyrite flotation was slightly better in the presence of chalcocite than in the presence of chalcopyrite in rougher flotation with all flotation conditions being the same.
