Development of Nitric Acid Benefication Technology of Phosphorite from in Presence of Ethanol

Abstract

The enrichment of phosphorites of Central Kyzilkum containing big amount of carbonates with nitric acid allows to obtain phosphorite’s concentrates applicable for sulfuric acid extraction. The optimum parameters of that process applied to phosphorite flour, mineralised mass and washed and dried phosphorite’s concentrate of CentalKyzilkum`s phosphorites were offered.
