The so far known method of obtaining alkali metal sulphates consists in the action of sulfuric acid on alkali metal chlorides. Another method consists in the action of water vapor and air at elevated temperature on transition metal sulphates and alkali metal chlorides. As a result of the reactions taking place, alkali metal sulfate and transition metal oxides, and hydrogen chloride are obtained. The significant amounts of hydrogen chloride present in the exhaust gases are the source for the production of hydrochloric acid. According to the invention, alkali metal sulfates and chlorine are obtained from a mixture of transition metal sulfates and alkali metal chlorides used in a molar ratio of 1: 2. The dispersants are heat treated at a temperature of 300 ° -800 ° C. in the presence of oxygen or an oxygen-containing gas. During the thermal treatment, the salt mixture is decomposed. The alkali metal sulphate is separated with the aid of water from the resulting sinter containing alkali metal sulphate and transition metal oxides with the aid of water in a manner known per se. The resulting exhaust gases are recirculated and, after the desired chlorine concentration has been obtained, all or part of the chlorine is released by known methods. Transition metal oxide, diatomaceous earth, aluminosilicates or mixtures thereof are used as dispersants. The dispersing substances are used in an amount of 5 to 50% in relation to the transition metal sulphate. The advantage of the method is the preparation of transition metal sulphates from waste, which pose serious difficulties in their handling and storage - products sought after in the inorganic industry. The resulting sinter after leaching The alkali metal sulphate water contains insoluble iron oxides which, after dehydration, can be partially recycled. The following examples are illustrated in the method according to the invention. Example I. By granulated mixture of the composition: 45% sulphate ferrous monohydrate, 40% potassium chloride and 15% ferric oxide were passed into air at 650 ° C. Chlorine was obtained from the exhaust gases in the amount of 21% of its initial content in the mixture. The obtained sinter after the completion of the reaction contained 58.6% of water-soluble sulfates in terms of K2SO4, .r, 2.5% of water-soluble chlorides in terms of on KC1, less than 0.5% water-soluble iron salts. Example II. Hot air with oxygen was passed through a salt mixture of 50% FeSO4, 34% NaCl and 16% FesOa (granule diameter 1-2 mm). Hot air of 10006C nature was mixed at the reactor inlet with the recycle waste gas so that the temperature of the inlet gas stream was 800 ° C. The temperature in the decomposition zone was kept at 65 ° C. The process was carried out in such a way that the heating rate of the reaction mixture was greater than 10 ° C / min. The waste gas stream contained chlorine and trace amounts of sulfur oxides. of chlorine was 52%. The decomposition products which were continuously removed were cooled with a stream of air and then water was leached. Only trace amounts of iron compounds (less than 0.01%), the degree of chlorine conversion passed into the aqueous solution. Claims 1. Method for obtaining alkali metal and chlorine sulfates from a transition metal sulfate and alkali metal chloride mixture, characterized by the fact that the granulated reaction mixture is subjected to thermal treatment in at a temperature of 300-800 ° C in the presence of dispersing substances in an atmosphere of oxygen or oxygen-containing gas, then, after cooling, the seeds are released from the resulting sinter The alkali metal is in a known manner with the aid of water, while the exhaust gases are recirculated and, when the desired concentration is reached, all or part of the chlorine is released from them by known methods. characterized in that an oxide is used. 1. as transition metal, diatomaceous earth, aluminosilicates or mixtures thereof dispersants. 3. The method according to p. 3. The method of claim 3, characterized in that the dispersants are used in an amount of 5 to 50% of the transition metal sulphate.
