Flotation columns are also practical, as their footprint is small and a proper height will allow for effective multi-stages separation (Moon and Sirois, 1983), akin to the operation of a distillation column with counter-current flow of coal- carrying bubbles up and ash-laden water down. Addition of wash water at the top of the column results in

Reverse column flotation of iron ore SpringerLink

The use of column flotation was considered for the “reverse flotation” of iron ore, where the gangue (quartz) was recovered in the froth product. This use of the froth for carrying the gangue mineral rather than carrying the valuable concentrate significantly changes the operational requirements of the column. The objective of this work was to determine which of several column flotation

phase, the selected flotation column will be used to process three coal samples while the second phase will involve the use of the enhanced gravity separator. Finally, the combination of column flotation and enhance gravity separation will be arranged to produce high quality clean coal from each of the samples.

Froth flotation Wikipedia

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.
