Mechano-Chemical Activation of Phosphorites of Central Kyzylkum in the Presence of Oxidized Brown Coal

Abstract

The article shows that deep dispersion of mixtures of ordinary phosphorite flour, or the pulverized fraction of phosphorites of the Central Kyzylkum with oxidized brown coal from the Angren deposit leads to the production of phosphoric organomineral fertilizers with a high content of the assimilable form of P₂O₅ and humic acids.
