Flotation separation of copper sulphides from arsenic ...

01/11/2014  Previous studies on either pre-oxidation of flotation pulp or Eh control during flotation reveal the complexity of selective separation of arsenic from non-arsenic copper minerals and a straightforward method to achieve the separation is not available. In this study, the flotation behaviour of arsenic and copper minerals was examined at Rosebery copper concentrator based on which

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 metal in finely disseminated particles which aggregate ...
