Phosphate ore processing for phosphoric acid

2013-11-29  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.
