| Abstract: | The impacts of the Rare Earth (RE) on the contents of available Phosphorus (P) and the physical character of the calcium superphosphate produced by the wet process on the basis of simulating the consumption of concentrated sulphuric acid, the slurry concentration and the cure conditions in different wet process were studied in laboratory, and the results show that adding RE into different wet process does not raise available P, but changes its physical character,for example, the composite is loose and the color is offwhite. |
