Phosphate Industry - Beneficiation Technology

For many years it has been common practice to use flotation to upgrade mined phosphate to produce marketable Phosphate Rock. Originally mechanical flotation cells were used, and in most cases the amount of phosphate lost in the flotation tailings was at a high enough level to warrant using scavenger cells, even though this was rarely done.

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.
