pH Control in Flotation of PGM Platinum Group Metal

2021-10-26  From my observations lab flotation tests I noticed that acidic pulp seemed to float fast, with a high mass pull at first and then the intensity of the froth dies down as time goes by. I was left wondering whether it would be ideal or not to induce acidic conditions so as to lessen residence time in flotation.

Effect of pH on the Recovery and Grade of Base Metal

2011-9-10  B. Froth Flotation Flotation is a physio-chemical process which exploits the differences in the electrochemical properties of mineral surfaces. All minerals are soluble in water to some extent, which results in the formation of an ‘electrical double layer’ at the mineral surface. Flotation depends directly on the
