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.
