Mechanochemical Activation in Manufacture of Defluorinated Forage Phosphate

摘要

The effect of preliminary mechanochemical activation of phosphate rock on the temperature of hydrothermal calcination and degree of defluorination in manufacture of defluorinated forage phosphates conforming to GOST (State Standard) 23 999-80 was studied. A mechanism of mechanochemical activation of phosphate raw materials, associated with changes in thermodynamic properties of the activated system, was suggested.
