60 Centuries of Copper: The Flotation Process

2021-7-19 · 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 ...

Effect of Copper and Iron Ions on the Sulphidizing …

The results show that a proper Cu 2+ concentration can increase the sulphidizing effect of copper oxide, while Fe 3+ inhibits the sulphidizing effect. Further analysis shows that Cu 2+ ions can reduce the surface potential, increase the S 2- adsorption, then generate more polysulfide, and therefore promote the sulphidizing flotation.
