How many tons of phosphorus can be obtained from 5 tons of phosphorite containing 40% calcium orthophosphate if the reaction product yield is 60%?
Ca3 (PO4) 2 + 3SiO2 + 5C = 3CaSiO3 + 5CO + 2P
orthophosphate mass = 5 t * 0.4 = 2 t (2000 kg);
amount of orthophosphate = 2000: 310 = 6.5 kmol
amount of phosphorus = 6.5X2 = 13 kmol
13 kmol – 100%
X – 60%
X = 7.7 kmol
mass of phosphorus = 7.7X31 = 240kg (0.24t)
Answer: 240 kg
