2020-1-8  Combining equal amounts of water-soluble P fertilizers, such as single superphosphate or triple superphosphate, with phosphate rock increases the uptake of P from the phosphate rock by 100% or more, when compared with sole phosphate rock application (Chien et al. 1996). This is due to the acidulating effect of water-soluble P on phosphate rock.

Process for reducing the grain size of phosphate rock ...

Two processes have proved to be suitable for reducing the grain size of coarse-grained phosphate rock: dry crushing and wet crushing. In dry crushing, the coarse-grained phosphate rock, which can have a moisture content of about 10 percent and more, is first subjected to drying whereby this moisture content is reduced to about 1-3 percent.
