Abstract

The purpose of the work is acceleration of the process of nitrate decomposition of local dolomite raw materials and study its processing into MgOH, MgO, liquid and granular magnesium fertilizers. We studied the effect of "PAA-gel" and "Struktol SB 2195" on the foam expansion ratio and filtration rate, as well as the influence of acid concentration and temperature on the rheological properties of the acidic pulp and the liquid and solid phases formed during its separation. The qualitative and quantitative compositions were determined. As a result, an increase in the filtration rate and a decrease in the rate of foaming were achieved.
