摘要：

Process of obtaining CaCO3 from the waste post-distillation liquid DS and post-filtration liquid from Solvay method of the soda production at 303 K was investigated. Reagents were dosed in a stoichiometric ratio without dilution, for different concentrations of the DS and post-filtration liquids. The dosage time was varied in the range 2-30 min, the reagent stirring rate was 500 rpm. For the obtained samples of CaCO3, the bulk and packing densities, water, paraffin oil and dibutyl phthalate absorption capacities, distribution of the particle size as well as the crystalline form were determined.
