5 Types of Phosphate Froth Flotation Process

The direct froth flotation process is to grind the phosphate ore until the minerals among the ore are dissociated after one stage grinding, suppress the gangue minerals by adding inhibitors, and then add the collector to enrich the phosphate minerals in the foam. This process must be combined with strong inhibitors to obtain best effect. It is mainly suitable for phosphate ore with phosphate

Ball-grinding tests were used to reduce the coarse fraction +315 μm. Grounded materials were sieved to 71–315 μm and combined with the scrubbed fraction in the flotation feed. Reverse-flotation tests of the phosphate-rich fraction (71–315 μm) have helped to improve the P2O5 grade to 27.1%, with a recovery rate of 92.4%. The enrichment of the low-grade-phosphate ore of the Tozeur-Nefta

You can choose a suitable model according to personal requirements. But Raymond mill has a

Mining and Beneficiation Phosphate Research Network

The concentrations of phosphate ores deposits are going to be low and phosphate ore beneficiation is becoming a real challenge for phosphate industry. The froth flotation could be considered up to now as a good solution but it consumes a lot of water and chemical reagents and leads to huge quantities of sludge (tailings). The R&D should explore other dry beneficiation pathways beside working
