The excess of magnesium chloride brines is formed during the polymineral ores processing in order to obtain potassium sulfate. One way to regenerate such brines is to produce artificial carnallite. It is necessary to purify these brines from sulfates for their further use as raw materials for the artificial carnallite production. In this work, the process of desulfurization of magnesium chloride brines with a solution of calcium chloride is studied. The temperature and the processing time, the magnesium chloride solutions concentration and the consumption of desulfurizing agent (calcium chloride) influence on the degree of magnesium chloride solutions purification from sulfate ions was determined. It has been established that almost all sulfate ions interact with calcium ion in 15 minutes and the desulfurization degree reaches 98,08 %. The increase in duration of the suspension mixing is necessary in order to establish equilibrium in the system and relieve the supersaturation in the solution. It has been shown that with increasing solutions saturation with MgCl2, the degree of the magnesium chloride brines purification from SO4 2– ion increases. Complete precipitation of calcium sulfate requires a certain excess concentration of calcium chloride.

1. In non-nephrectomized animals the addition of adrenalin to sodium chloride solutions or to mixtures of sodium chloride and calcium chloride solutions increases the amount of urine and of ascites, and diminishes the intestinal fluid (this diminution takes place only with mixtures of solutions of sodium chloride and calcium chloride, the quantity of intestinal fluid remaining approximately unchanged in the sodium chloride series). 2. In nephrectomized animals the addition of adrenalin to sodium chloride solutions or to mixtures of sodium chloride and calcium chloride solutions again increases the ascites and diminishes the amount of intestinal fluid in both sodium chloride and sodium chloride plus calcium chloride series. 3. We find, therefore, a summation of the action of calcium chloride and adrenalin in regard to their influence upon the formation of ascites, an antagonistic action in regard to the elimination of urine; here the influence of calcium chloride in diminishing the urine is more potent than is the action of adrenalin in increasing the amount of urine. The adrenalin decreases the elimination of fluid into the intestines and in this case we note a summation of the actions of calcium chloride and of adrenalin. 4. We see, therefore, that adrenalin and calcium chloride influence the amount of ascitic fluid and of intestinal fluid in the same direction. The amount of urine is, however, decreased by calcium chloride and increased by adrenalin. 5. If we increase the rapidity of inflow of the solutions and simultaneously decrease proportionately the time of the infusion, the amount of ascites and intestinal fluids in nephrectomized animals remains approximately unchanged, as compared with the amounts obtained at the usual rate of inflow.
