Embodiment Construction
[0036] Embodiment: Get the phosphogypsum discharged by a certain enterprise in Guizhou Province as raw material, and its chemical composition (mass fraction) is as shown in the following table after testing:
[0037] Composition SO 3 CaOSiO 2 F MgO Al 2 o 3 Fe 2 o 3
[0038] Content% 39.46 31.40 4.99 0.2 0.04 0.04 0.21
[0039] Ingredient P 2 o 5 Na 2 OK 2 O TiO 2 MnO loss on ignition Total
[0040] Content% 1.18 0.09 0.09 0.07 0.01 21.76 100
[0041] The first step is to prepare mixed powder: the waste phosphogypsum produced in the production process of wet-process phosphoric acid is cleaned with clean water and dried, and sent to a tunnel kiln to be calcined at 1300-1360°C for 25 minutes with civil gas to remove the phosphogypsum part of moisture, P 2 o 5 and fluorine, and then grind the calcined charge to 400-450 mesh for later use. At this time, the composition of phosphogypsum has changed, and its chemical composition (mass fraction)...
