Abstract (en)
[origin: WO2021156551A1] The invention relates to a method for grinding phosphate rock in the presence of a particular anionic polymer having a molecular weight of between 1000 and 90000 g/mol, which makes it possible to control the extent (S) of the volume distribution of the particle size of obtained phosphate mineral particles. The invention also relates to a method for improving the production yield of a phosphate rock grinding method.
