PLThe longest term of the patent until September 24, 1941. The invention relates to a further development of the method of obtaining sulfur from calcareous sulphates described in the patent No. 5,926, with the addition of the raw product dissolved in molten sodium chloride and the addition of coke is obtained According to the present invention, magnesium chloride is added to the concentration of alkali chloride and calcium sulfate before or after reduction with coke to facilitate the conversion of alkaline sulfides to alkali chlorides. Magnesium chloride has heretofore been used to obtain hydrogen sulfide on wet road'1. However, this is a kind of siliticide and leads to the contamination of wastewater. According to the present invention, almost dehydrated magnesium chloride is added to the alkali alloy containing reduced sulfate. Large amounts of hydrogen sulphide are then released, the magnesium oxide is detached, and the calcium chloride is easily formed from the non-soluble calcium sulphides; it is easy to dissolve in the molten alkali chlorides, the formation of hydrogen sulphide can be increased and facilitated by injection) this method is obtained very quickly volatile from calcium sulphides, a slightly liquid alloy, consisting of alkali and calcium oxide chlorides In this alloy, the magnesium oxide is quickly deposited so that it can be easily removed. If the alloy of alkali and calcium chloride is free from magnesia and containing coke in excess, to be used to redissolve and reduce the retinates of chrysanthemums, then: work can be carried out continuously, 2-o remove the disadvantages related to the work in a wet way, namely: expensive preparation of alkali silides by evaporation and contamination of the alloy by post-crystalline liquors. As a result, the magnesia is constantly separated by sedimentation, and the calcium chloride which forms and forms are continuously circulated, and a pure calcium chloride alloy containing only alkali chlorides is obtained, which is very easy to clean and does not allow the formation of post-crystalline loams contaminating the alloys.
