■ Die Herstellung von Bariumoxyd aus einem Gemisch von Eisenoxyd und Bariumsulfat ist bekannt (Dammer, Anorg. Ch., II. Band, 2, S. 377; Patentschrift 17385, Kl. 75)·■ The production of barium oxide from a mixture of iron oxide and barium sulfate is known (Dammer, Anorg. Ch., Volume II, 2, p. 377; Patent 17385, Class 75)
Das vorliegende Verfahren bezweckt die Darstellung von Erdalkalihydroxyd aus einem Gemisch von Erzmetallsulfiden und Erdalkalisulfaten. The present process aims to prepare alkaline earth metal hydroxide from a Mixture of ore metal sulphides and alkaline earth sulphates.
ίο Das Verfahren besteht darin, daß man das Erdalkalisulfat mit dem Erzmetallsulfid, beispielsweise Schwefeleisen mit Bariumsulfat, mischt und dieses Gemisch in einem elektrischen Ofen oder überhaupt in einem Ofen oder einer Retorte bis auf die für die Reaktionswirkung erforderliche Temperatur erhitzt. Der für die Herstellung des Erdalkalioxyds wesentliche chemische Vorgang kann durch folgende Gleichung zum Ausdruck gebracht werden.ίο The procedure consists in that one Alkaline earth sulphate with the ore metal sulphide, for example iron sulphate with barium sulphate, mixes and this mixture in an electric oven or in an oven at all or a retort to the temperature required for the reaction to take place. The chemical process essential for the production of the alkaline earth oxide can can be expressed by the following equation.
7 Ba S O4 + 2 Fe S = 7 Ba O + Fe2 O3 + 9 S O2 .7 Ba S O 4 + 2 Fe S = 7 Ba O + Fe 2 O 3 + 9 SO 2 .
Daneben findet jedoch noch die Bildung von anderen Verbindungen, wie Ba S Fe2 O3 und BaOFeS statt.In addition, however, the formation of other compounds such as Ba S Fe 2 O 3 and BaOFeS takes place.
Das so erhaltene Produkt, welches in Wasser nur teilweise löslich ist, wird gepulvert und mit 10 Prozent Kohle gemischt und wieder im elektrischen Ofen oder sonstwie bis auf die für die Reaktionswirkung erforderliche Temperatur erhitzt.The product thus obtained, which is only partially soluble in water, is powdered and mixed with 10 percent coal and put back in the electric furnace or something else heated to the temperature required for the reaction to take place.
Durch die Reduktion der beim ersten Glühen erhaltenen Doppelverbindung Ba O Fe2 O3 mit Kohle entsteht ein Produkt, aus. dem das Bariumoxyd mit Wasser leicht ausgelaugt werden kann. In derselben Weise können die Oxyde des Strontiums und Calciums gewonnen werden.By reducing the double compound Ba O Fe 2 O 3 obtained during the first annealing with carbon, a product is created from. which the barium oxide can easily be leached with water. The oxides of strontium and calcium can be obtained in the same way.
