Recovery of PGMs from an oxide ore by flotation and leaching

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

The effect of conditioning on Froth Flotation

Adsorption of collector was measured indirectly using UV spectrophotometry. This was used to measure the removal of collector from solution, from which adsorption onto the mineral surface was inferred (by difference). Microflotation was chosen as the technique used to relate flotation response to adsorption.
