Mechanical activation of the phosphate rock

thirds of the phosphate fertilizers are derived from rock treated with phosphoric acid; during the past 30 years, a large proportion of the net addition to phosphate fertilizer production has been in the form of phosphoric acid based products. About 90% of the world phosphoric acid output is used for fertilizer production (Fig. 1.).
