Аннотация:

The paper considers issues of mechanical activation of phosphate fines, low-grade by its chemical composition and off-grade by its grain fineness mineral raw material. Results of the research showed that increase in the content of soluble form of Р[2]О[5] is more than in three times, from 17.61 to 53.15%. Specific surface of the activated phosphate fines increases from 0.25 to 0.86 m{2}/g. The activation increases degree of dispersion and changes morphology of the phosphate fines disperse particles.
