Abstract

The main parameters of dolomite phosphorization and the successive granulation of the product in a laboratory pan
granulator were studied. The physico-chemical properties of granulated dolomite such as size of granules, moisture
content, granules crushing strength and chemical composition (CaO, MgO and P2O5) were measured. Dependence of
granules size percentage distribution of product on the amount of dolomite treated by phosphoric acid under various
granulation conditions was determined. The main parameters of phosphorization were determined and the main physicochemical
properties of granulated dolomite were examined too. The results of investigation allow optimizing the process
of reaction of dolomite with phosphoric acid in order to obtain a granulated product containing calcium, magnesium and
phosphorus for using in agriculture.
