The present invention relates to a method for beneficiation of phosphate rock by a thermal treatment, wherein an appreciable increase in P 2 O 5 and decrease in cadmium contents in the calcined product are achieved. According to the invention, the phosphate rock is contacted with hot gases possessing a temperature in the range of between 700 C. to 1600 C. for a period of below 60 seconds

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

Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals.The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate rock is enriched ( beneficiated ) to at least 28%, often more than 30% P 2 O 5.This occurs through washing, screening

Mar 01, 2020 Beneficiation of phosphate ore is a process which includes washing, flotation and calcining. Froth flotation is used to concentrate the mined ore to rock phosphate. The mined ore is crushed and washed, creating a slurry, this ore slurry is then treated with fatty acids to cause calcium phosphate to become hydrophobic
