Abstract

This paper presents the results of incomplete decomposition of Central Kyzylkum non-conditioned phosphorites with sulfuric acid (30-70% stoichiometric norm relative to CaO) and its subsequent processing into phosphorus-humus fertilizers with active turbidity. Optimal ratios of starting materials in the production of phosphorus-humus fertilizers on the basis of active turbid and non-conditioned phosphorites and the rate of sulfuric acid for the decomposition of Central Kyzylkum non-conditioned phosphorite were determined.
