Jan 01, 1992 Comminution consists one of the major items in the production cost list of the phosphate rock processing. Particle size of the rock is an important parameter in the acidulation reaction because the reaction rate is directly proportional to the total surface area exposed to the acid. Beneficiation of Phosphate Rock-A State of the Art Review.Beneficiation of Phosphate Ore examines various methods for processing phosphate rock, an important mineral commodity used in the production of phosphoric acid. The majority of phosphoric acid is produced by the wet process, in which phosphate rock is reacted with sulfuric acid to produce phosphoric acid and gypsum (calcium sulfate dihydrate).Abstract. Beneficiation of phosphate ores by dry electrostatic processes has been attempted by various researchers since the 1940’s. The underlying reasons for developing dry processes for phosphate recovery are the limited amount of water in some arid regions, the flotation chemical costs, and the wastewater treatment costs.1 From one-time basal application of PR. 2 Private and environmental benefits are discounted by 10 and 3 , respectively. 3 Based on 3 discount rate. 4 Most profitable alternate product is included here. 5 Discount rates range between 5 and 15 for private benefits and between 1 and 5 for total benefits. 6 Phosphate rock concentrate.
