The method for preparing iron oxide red and co producing trisodium phosphate from iron phosphate comprises the following steps:
1. taking iron phosphate powder and sodium carbonate as raw materials, mixing them evenly and drying them
2.Calcine the mixed powder of step :
( 1 ) at 450 ~ 650 ºC for at least 2 hours, and absorb the P2O5 gas generated during calcination with the washing water of washing filter cake to form sodium phosphate solution( 3) The material calcined at low temperature in step
( 2 ) is roasted at 700 ~ 850 ºC for 1 ~ 4 hours, and the P2O5 gas generated in roasting is absorbed with the washing water of washing filter cake to form sodium phosphate solution
( 4 ) Soak the material of step (3) at 80 ~ 90 ºC for at least 1 hour, and filter to obtain filter cake and filtrate
( 5 ) The filter cake is washed with water and dried to obtain the finished product of iron oxide red
( 6 ) The sodium phosphate solution obtained in steps (2) and (3) is mixed with the filtrate obtained in step (4) to obtain trisodium phosphate solution, which is concentrated, crystallized and dried to obtain trisodium phosphate finished product.
