PRODUCTION OF FERTILIZERS BASED ON OXIDIZED BROWN COAL AND PHOSPHATE RAW MATERIALS

Organomineral fertilizers were obtained based on the Central Kyzylkum phosphorite raw material. For the study, samples of oxidized coals of Angren brown coal were taken. The technical composition and humic acid content of the coal were determined using standard methods. During the co-grinding of phosphate ores with oxidized coal, brown coal significantly increases the content. An increase in the content of citric and water-soluble forms of phosphate was observed.
