The viscosity and density of nitric acid extracts obtained by treating Dzhamansay limestone with nitric acid have not been studied and the relevant data are not available in the literature. The study of the viscosity and density of the hoods is caused not only by the above considerations, but also by the fact that in the design of some production apparatus and plants there is often a need for knowledge of the viscosity and density of liquid flows. Thus, the decomposition process of Dzhamansay limestone with nitric acid was studied depending on the size of the limestone pieces, concentration, nitric acid rate and duration of the process. The optimal decomposition conditions are determined. The possibility of suppressing foam by preliminary decarbonization of high-carbonate waste by circulating pulp is shown. The rheological characteristics of solutions and pulps formed at various stages of the process are determined.
