Ecologically expedient complex processing phosphate ores by phosphates and hydrosulphates of alkaline metals

Abstract

Complex processing of phosphate ores by sulphates and hydrosulphates of alkaline metals enables to expand raw base at the expense of usage of balance phosphate ores and eliminate formation of non-soluble wastes. The obtained complex mineral fertilizers by the offered method can be used on any soils without restriction of types of agricultural crops.
