Investigation of rheological parameters of ammo phosphate pulps based on substandard phosphorus-containing raw materials

This study presents the results of studies on the study of rheological characteristics (density and viscosity) of both non-one stripped off and one stripped off ammo phosphate slurries obtained by decomposition of the phosphorus-containing mineralized mass of the Central Kyzyl-Kum deposit with phosphoric acid, followed by separation of the calcium phosphate pulp into solid and liquid phases and pre-ammoniation pH 4.0-4.5. The effect of the rate of extraction phosphoric acid, pH of the medium and temperature on the density and viscosity of one stripped off and not one stripped off ammo phosphate pulps was established. The obtained values of rheological characteristics substantiate the mobility of ammo phosphate slurries, which will ensure their pumping without any particular difficulties on the technological equipment.
