Phosphate Beneficiation Process

 · Phosphate beneficiation plant In the treatment of phosphatic shales for recovery of phosphate, a simple low cost flexible flowsheet is highly desirable. Since all grades of ore from low to high P2O5 content may occur in a deposit it is important to consider the possibility of either mixing the ores or to segregate them into grades for separate treatment.
