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).

"Separation of Dolomite from Phosphate at Low Cost and ...

Magnesium (MgO) in phosphate rock causes numerous problems in the phosphoric acid manufacturing process, including reducing filtration capacity, increasing sulfuric acid consumption, and making it difficult to meet product grade. MgO-containing minerals are fully dissolved and usually coexist in phosphoric acid by acid hydrolysis reaction to form Mg(H2PO4)2.
