In this article, we conducted research on the production of calcium and magnesium phosphates based on dolomite and phosphoric acid. The purpose of adding different concentrations of phosphoric acid to dolomite is to determine the optimal concentration. Then samples were taken by adding phosphoric acid of the appropriate concentration to the dolomite in various mass ratios. The total and soluble forms of calcium oxide, magnesium oxide, phosphorus pentoxide contained in the obtained samples, as well as the levels of decarbonization, were studied. Research results have shown that the total forms of calcium oxide, magnesium oxide and phosphorus pentoxides in dolomite decrease after acid concentrations from 5% to 25%.
