In general, the phosphate ore available in syrian mines has high amounts of chlorine and caop205 ratio. the low grades of syrian phosphate were beneficiated utilizing physical methods such as crushing, grinding, wet screening, desliming, and flotation. the beneficiation processes upgraded the phosphate by increasing p205 content upto gt28.00 .

Manufacture of phosphate fertilizer by wet processing. if you want to make phosphate fertilizer by wet processing, there are drum granulation equipment for your reference. this machine is a representative of wet type compound fertilizer pelletizers. it utilizes rotating cylinder for making pellets.
Process description wet process phosphoric acid-dihydrate phosphoric acid is produced by reacting sulfuric acid h 2 so 4 with naturally occurring phosphate rock.the phosphate rock is mined, dried, crushed until 6070 of the rock is less than 150 m in diameter, and then continuously fed into the reactor along with sulfuric acid.
In wet process, phosphate ore is decomposed by mineral acid. sulfuric acid is widely used to decompose phosphate rock to produce phosphate fertilizer for its easy separation of h 3 po 4 from phosphogypsum and hydrogen fluoride. 1 c a 5 f p o 4 3 5 h 2 s o 4 5 n h 2 o 3 h 3 p o 4 5 c a s o 4 183 n h 2 o h f
