Phosphate Ore Processing For Phosphoric Acid Production

Nov 29, 2013 Abstract. Phosphoric acid (H 3 PO 4, PA) is an industrial acid, produced from two main types of phosphate rock sedimentary and igneous.In the classical wet process, wet process PA is produced by a reaction between the ore and sulphuric acid, forming 30 solids thick slurry, in three stages acidulation, filtration and concentration to produce a 50 P 2 O 5 acid.

5 Types Of Phosphate Froth Flotation Process

5 Types Of Phosphate Froth Flotation Process

Apr 23, 2020 Froth flotation is the most widely used phosphate ore separation process. Because of the nature of the phosphate ore, such as mineral types and content, disseminated particle size, its separation difficulty and flotation types varies. Phosphate ore is divided into siliceous phosphorite, calcareous phosphorite, and siliceous phosphorite according to the chemical composition of the minerals.The froth flotation types differ from different types of phosphate.
