Dicalcium phosphate shows the most commonly used production method is known as the wet acid route in which rock phosphate is reacted with sulphuric acid to produce phosphoric acid. After concentration and purification to reduce the level of undesirable elements this phosphoric acid is

Environmental Impact Of Phosphate Mining And Beneficiation
Environmental Impact Of Phosphate Mining And Beneficiation

Phosphorus is common within geological materials. The average continental crust contains 0.27 P 2 O 5. 1 Phosphorus is the primary resources to produce fertilizer and phosphorous-based products. 2 Phosphorus is neither substitutable nor recyclable therefore the total demand must be provided through the mining beneficiation and chemical processing of phosphate ores.
