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.
Without this flotation step, the fine coal would upset the specific gravity range of the natural media and create a large circulating load of coal fines in the media. The media is a closely controlled fraction from the tailings produced by the main flotation section with respect to density and size ( …

Coal flotation is a complex process involving several phases (particles, oil droplets and air bubbles). These phases simultaneously interact with each other and with other species such as the molecules of a promoting reagent and dissolved ions in water.
The amenability of beneficiating a fine hard coal from Hwa-Sun coal mine using column flotation has been studied using a CoalPro flotation column developed by Canadian Process Technologies (CPT).

Flotation is a complex multifaceted process that is widely used for the separation of finely ground minerals. The theory of froth flotation is complex and is not completely understood. This fact has been brought many monitoring challenges in a coal processing plant. To solve those challenges, it is ...
The froth flotation machine is applicable for separating non-ferrous metal, black metal, noble metal, non-metal mineral, raw body and materials of chemical industry, which are subject to coarse separation, swept separation and flotation, so the useful ore are reclaimed.

30 Million tonnes of coal is washed every year in Indian coal washeries. 20 - 30% of coal in the form of fines are produced and are being lost as tailings. Veryfew washeries have the facilities to treatthese coal fines. The standard existing coal beneficiation techniques are not effective to recover fine coal from these coal washery tailings. ...
column flotation, a clean coal with an ash content of 10.1%at a yield of 72.0% with 85.6% combustible recovery can be obtained at the same regent dosages and solids concentration.
We had to calculate the amount water needed first as we used 250 g of coal at 10% solids by mass, in the laboratory flotation cell. Under part A: Then, amount of frother of MIBC, which was equivalent to 0.10 kg/t had to be calculated.
The amenability of beneficiating a fine hard coal from Hwa-Sun coal mine using column flotation has been studied using a CoalPro flotation column developed by Canadian Process Technologies (CPT). After initial testwork using a batch flotation cell to determine the optimal flotation conditions, tests were carried out to compare its performance with the column.
Coal flotation is characterized by the chemical and petro-graphical composition of coal and its rank. In addition, size and sp . gr. of coal particles, pulp density, rate and uniformity of feed, conditioning, type of reagents, pH, presence of clay and type of flotation machines are the other variables which influence the coal flotation.
The results show when adding to OP emulsifier and the proportion of water and oil is 6:4, flotation effects is the best, the yield of clean coal is 88.67%, the ash of clean coal is from 9.16% down to 8.63%, the yield of tailings is 11.32% .
At Stratford Coal in NSW, Australia, a single mechanical flotation cell has been installed as a scavenger to treat Jameson cell tailings (Euston, 2010i). Figure 5, below, summarises the improved combustibles recovery achieved with secondary flotation at Stratford Coal.

The device consists of a flotation cell, identified in Figure 3 as 1, in which aerators are located allowing the air to flow into the cell, and distributors ensuring a steady flow of slurry on the froth layer formed in the flotation cell.
EFD is the world leader in column flotation technology with over 900 installations. Columns are used for floating well-liberated ores. Typically they produce higher grade and have lower power costs than conventional cells.

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.
