Froth flotation - Wikipedia

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.

Coal flotation cells | Engineer Live

The majority of coal comes off the first cell due to the rapid coal flotation kinetics. After this there is a large drop off in mass yield. The first cell in the bank recovers around 60-70% of the mass in the feed, and then falls off significantly in the remaining cells. Though they are all in the same bank, the individual cells have to operate under very different duties in terms of froth ...

Frother Dependency in Coal Flotation - [email protected]

Frother dependency in coal flotation was examined using four coals varying in origin, rank, type, proximate analysis and feed size distribution and three different types of frothers, natural product (pine oil), synthetic alcohol (MIBC) and a polyglycOl based synthetic frother, N 8586. No frother was found to be unique. MIBC and N 8586 were found to produce the best results for Bhelatand and ...
