About 145 million tons of phosphates were produced in 2006 (Jasinski, 2007). The run-of-mine phosphate ores are mostly of low grade which need processing or upgrading to match the market grade (around 30% P 2 O 5) (Straaten, 2002). The processing techniques of phosphate ores depend on the type of phosphate minerals …

Details
Flotation separates valuable minerals (copper, lead, zinc, iron, and phosphate too) from the contaminating minerals in the ore (sand in this case). In the direct flotation process the valuable mineral is coated with a special hydrocarbon (fatty acid) that makes coated particles behave the same as a waxed car.
Details
The concentration process produces a non-magnetic tailing containing apatite, with grades between 1–3% P 2 O 5 [ 9 ]. Flotation is a method based on the difference in physicochemical properties between valuable minerals and gangue [ 10 ]. The wettability of the surface plays a decisive role in its buoyancy.
