How Does Pulp Concentration And pH Affect Froth Flotation ...

In froth flotation process, the pH value of the pulp needs to be paid close attention to at all times. The pH value needs to be measured with a test paper every once in a while to ensure that the pH value remains at a stable value. And the pulp concentration and liquid level need to be stable, ensure scraping, to scrape out the full plate.

Graphite Processing - Froth Flotation (Sulphide & Oxide ...

I would think that you are not too worried about maximising the size of the graphite particles so gentle attrition is the way forward. You need to have a way to physically separate the clay from the graphite before attempting the separation, which would probably consist of classification (depending how fine the graphite has become) then flotation in the presence of dispersant at low percent ...

However, a few studies claimed that amines are capable of floating calcite at and above pH 10. Thus, it can be summarized that pH 7–8 is the most suitable pH for sulphide/silicate flotation from calcite. Collector concentration, flotation and conditioning times are other parameters, having a higher impact on these flotation results.
