Proponowano dotychczas otrzymywac siarke z siarczanów wapniowców przez rozpuszczenie ich w stopionych chlorkach alkaljów, Pnzy tych sposobach dla otrzyma¬ nia siarczków wapniowców stosuje ;sie we¬ giel staly albo w postaci gazów redukuja¬ cych.Okazalo isie przytem, ze weg;ieil staly nie daje sie dobrze mieszac ze stopem. Skut¬ kiem wywiazywania sie gazów wydostaje sie on na powierzchnie, gdzie sie szybko spala i nie zostaje w dostatecznym stopniu wy¬ korzystany dla redukcji. Redukcja skut¬ kiem tego jest niecalkowita i wymaga znacznego nadmiaru wegla.Sposób wedlug wynalazku tern sie róz¬ ni od sposobów znanych, ze stosuje sie tu wegiel w postaci koksu, i tem, ze po reduk¬ cji oddzielenie chlorku alkalicznego od siarczku wapniowca odbywa sie przez osa¬ dzanie, poczerni górna warlstwe chlorku al¬ kalicznego odprowadza sie (spuszcza), a siarczek wapniowca przez traktowanie pa¬ ra albo kwasem zamienia isie na tlenek, wzglednie sól wapniowca i siarkowodór.Koks daje isie dobrze mieszac ze sto(pem i energicznie dziala redukujaoo.Wynalazcy stwierdizilii dalej, ze siarcz¬ ki wapniowców w stopie doskonale od¬ dzielaja sie od chlorków alkaljów przez od-stanie. Skutkiem tego po redukcji koniecz¬ nem jest klarowanie sie stopu. Warstwe chlorku mozna sipu&cic i zpowu uzyc do roz¬ puszczania nowych ilosci siarczanu wap¬ niowca. Otrzymany sialrezek wapniowca dla otnzymaniia siarkowodoru traktuje sie w sposób opisany powyzej,.Wreszcie nalezy wspomniec, iz dla o- trzymywania siarczku sodu i siarczku po¬ tasu z odpowiednich siarczanów zapomoca wegla i soli kuchennej proponowano juz sto¬ sowac koks. Lecz przy traktowaniu siaircza- nów wapniowiców dotychczas jeszcze koksu nie uzywano. PLHitherto, it has been proposed to obtain sulfur from alkaline earth sulphates by dissolving them in molten alkali chlorides. These methods are used to obtain alkaline earth sulphides by using either solid coal or in the form of reducing gases. It has also turned out that mix well with the alloy. As a result of the gas release, it escapes to the surface, where it burns quickly and is not sufficiently used for reduction. The reduction as a result is incomplete and requires a considerable excess of carbon. The process of the present invention differs from the known methods of using carbon in the form of coke, and that after reduction the separation of the alkali chloride from the calcium sulphide is carried out. by precipitation, the black top layer of alkali chloride is drained off (drained) and the calcium sulphide is converted by treatment with steam or acid to an oxide, or an alkali salt and hydrogen sulphide. The coke can be mixed well with one another and vigorously. The inventors have further found that the alkali sulphides in the alloy are perfectly separated from the alkali chlorides by settling. Consequently, after reduction, the alloy must be refined. The chloride layer can be siphoned and used for dissolving. new amounts of calcium sulphate The obtained calcium sulphate for the preparation of hydrogen sulphide is treated as described above. Finally, it should be mentioned that for preserving Coke has already been proposed for the use of sodium sulphide and potassium sulphide from the corresponding coal sulphates and table salt. But coke has not yet been used in the treatment of calcium sulphates. PL
