2010/08/06· Coal flotation is commonly carried out with a combination of an oily collector (e.g. fuel oil) and a frother (e.g. MIBC). All coal flotation systems require the addition of a frother to generate small bubbles and to create a stable froth
2016/10/31· The ability to use wash water to remove entrainment revived the interest in flotation columns. L/D ratio is also significant for ultrafine particles. The coal industry is shifting to larger columns, up to 4.5m diameter and greater.
circuit so agitation can promote dispersion into the pulp. Water-soluble frothers, (Dowfroth 250 and Cyanamid AF65) are often stage-added along a flotation bank to maintain a stable froth phase and reduce consumption.
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as …
