摘要：
The process for raising the agrochernically active citric-soluble phosphorus oxide content in apatite is reported on example of ores of the Seligdarskoe deposit by employing the mechanochemical activation with introduction of zeolites. The process for multistep extraction with citric-acid solutions is proposed to evaluate complete solubility of activated apatites utilized as fertilizers. The potentialities to prolong the agrochemical activity of apatite component in zeolite-phosphate mixtures are shown by introducing gradually additional amount of zeolite as it is saturated with calcium cations.
