Full article: Impact of Pyrite Textures Prevalence on Flotation
At the Mount Isa copper deposit, framboidal or 'carbonaceous' pyrite has been an ongoing challenge to the copper concentration operation, reducing the flotation circuit's efficiency. Previous work by Yenial-Arslan et al. showed that high pyrite recoveries could be strongly linked to the prevalence of fine-grained pyrite.

The roughing-table concentrate carries about 4 1/2 per cent. copper and 38 per cent. iron. Flotation and table concentrate mixed, forming the mill concentrate, assay 9 per cent. copper, 30 per cent. iron and 16 per cent. insoluble. Flotation tailing assays about 0.4 per cent, copper. The recovery by flotation is about 82 per cent.
(PDF) Application of Knelson concentrator for beneficiation of copper
The beneficiation of high talc-containing copper–cobalt flotation tailings was studied by centrifugal gravity concentration. It was found that copper and cobalt minerals were finely disseminated in the gangue matrix so that conventional gravity concentration using spirals and shaking tables would be ineffective.

60 Centuries of Copper: The Flotation Process
The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the ...
