successfully to South African coal fines, which are difficult to float, pilot scale testing was done on coals from the Water­ berg, Soutpansberg and some of the Natal coalfields. Pneumatic flotation is compared with standard laboratory flotation as well as with full-scale conventional flotation.

Coal in South Africa - Wikipedia

South Africa is one of the seven largest coal-producing and one of the top five coal-exporting countries in the world. More than a quarter of coal mined in South Africa is exported, most of which leaves the country via Richards Bay.

Choosing the correct flotation reagents for coal recovery ...

Significantly, Ekofol which is a combination collector-frothing reagent achieved an 8% higher recovery rate in laboratory and on-site testing in South Africa than local reagents. Kottmann says that in Germany coal is extracted from depths of up to 1000 to 1200 metres below surface and, for this reason flotation reagents are highly developed to optimise beneficiation and reduce production costs.

Flotation | Mining | SGS South Africa

Flotation is an incredibly robust and versatile process that is well accepted around the world. It works equally well on mixed sulfide, oxide, silicate and other ores. It relies on generating a population of bubbles of suitable size that can carry the hydrophobic target mineral (usually but not exclusively sulfide minerals) up to be recovered.
