Tests conducted on coalburg China Flotation Machine
Posted On 16/05/2018 07:43:55 by mixingtank

The coalburg seam coal is an example of difficult to float bituminous coal. Laboratory tests conducted on coalburg China Flotation Machine feed sample revealed recovery values around 28% with 15% product ash when using fuel oil as collector under natural pH conditions.

The improvement is believed to be result of the release of humic acids from the surface and the dispersion of clay particles thereby leaving a more hydrophobic surface.

A detailed study showed that increasing pH from natural value of 5.6 to 7.5 provided a significant improvement in recovery of approximately 32 absolute percentage points.
