Phosphate Ore Process

2018-6-7AbstractPhosphoric acid H3PO4, 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 50P2O5 acid.

  • Principle And Technology Of Ammonium Phosphate

    Principle And Technology Of Ammonium Phosphate

    2019-5-24A modified process for the production of ammonium phosphate fertilizer from the middle-quality phosphate ore was proposed. In this process, dilute phosphoric acid produced by the dihydrate process is neutralized by ammonia and the slurry is then concentrated. This effectively solved the scaling in the heater during phosphoric acid concentration.
