Mechanism and application on sulphidizing flotation of ...

Therefore, the application of flotation in copper oxide ore has attracted extensive attention [7−9]. The flotation of copper oxide can be mainly divided into direct flotation and sulphidizing flotation. The collectors for direct flotation are fatty acids, fatty amine, petroleum sulfonate and hydroximic acids [10,11].

(PDF) Improving the efficiency of oxide copper–cobalt ores ...

The maximum PGM flotation recovery achieved using sulphide co-collector schemes was 55.1% 3E (Pt, Pd, and Au). Application of the hydroxamate oxide collector improved the flotation recovery to 74.7% 3E. The superior PGM recoveries achieved with hydroxamates probably lies in their ability to form complexes with base metals such as iron.
