Extraction Phosphoric Acid From Washed Calcined Phosphorite Concentrate
Keywords:
mineralized mass, sulfate acid, extraction phosphate acid, decomposition coefficient, separation coefficient and filtration rate.Abstract
The article presents the results of studying the processes of extractive phosphoric acid production from phosphate waste - mineralized mass (MM) - formed during the thermal processing of Central Kyzylkum (MC) phosphorite by the clinker method. The influence of sulfuric acid concentrations on the quality indicators of the obtained EFK was studied, as well as the processes of extracting EFK from phosphate acid gypsum slurry using different concentrations of a phosphate acid solution.
