Control of Cation-Exchange Interaction between Zeolites and Phosphates on the Basis of Soft Mechanochemical Activation

Journal of Mining Science Aims and scope

Abstract

The behavior of clinoptilolite-phosphorite mixtures in the citric-acid medium and the influence exerted by mixture composition on kinetics of extracting P2O5 into 2% citric acid solution are investigated. It is established that as the zeolite : phosphorite mass ratio grows, the content of citric-soluble P2O5 increases in the mixtures, and the preliminary soft mechanochemical activation of phosphorite raises extraction of phosphorus to the acid media by a factor of 10-15. This favors the solution of agrochemical problems using zeolite-phosphate mixtures of different composition.
