Froth flotation - Wikipedia

People used to float -0.5mm coal in flotation cells in 1960s,70s and 80s, but now they have switched to -0.25mm flotation. It is recommended that maximum size particle that you try to float be 0.3mm. The reason is that 0.5mmx0.25mm flotation requires more residence time than 0.25mmx0 flotation.

Coal - Applications | Jameson Cell

The Jameson Cell is now the industry standard with over 100 coal cells installed by 2010 in Australia alone. In a Coal Handling and Preparation Plants (CHPP) gravity separation techniques are used to separate coal from ash. At fine particle sizes (below 500 µm) gravity separation is inefficient and flotation is required.

Productive froth flotation technology | FL

A flotation circuit's performance is affected by both pulp and froth phase recovery. And it is inherent in mining operations that manual control by operators who look at the cell surface periodically and then take action does not really maintain stable operating conditions.

Flotation | ore dressing | Britannica

Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to

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.

flotation – Mining Mill Operator Training

Flotation Circuits. Flotation circuits are typically comprised of rougher, scavenger and cleaner flotation banks. Rougher and scavenger banks are focused on recovery and thus provide maximum residence time. Rougher banks can be large with the number of cells being 5 or greater. Scavenger cells are the last line of defense for avoiding losses.
