Description

Verfahren zur= Aufarbeitung von Salmiakschlacken. Salmiakschlacken,, das sind die in den Verzinkereien und verschiedenen Hüttenbetrieben abfallenden Lötsteinreste, enthalten neben Zink noch bedeutende Mengen Ammoniaksalz, insbesondere Chlorammon. Bei der bisherigen Aufarbeitung, die in Zinkhütten erfolgte, wurde letzteres einfach verloren gegeben.Process for = processing of ammonia slag. Ammonia slags ,, these are the waste in the galvanizing plants and various metallurgical plants Solder stone residues, in addition to zinc, also contain significant amounts of ammonia salt, in particular Chlorammon. During the previous work-up, which took place in zinc huts, the latter was the case just given lost.

Es zeigte sich nun, .daß das Ammoniak salz leicht und ohne Beeinträchtigung der Zinkausbeute gewonnen werden kann, wenn folgendermaßen verfahren wird: Die Salmiakschlacke wird in wäßriger Lösung mit Bariumsulfid versetzt in einer .dem Zink äquivalenten Menge. Es bildet sich unlösliches Zinksulfid, das abfiltriert wird und eine Lösung von Bariumchloril und Ammoniumchlorid. Diese beiden wertvollen Produkte können durch fraktionierte Kristallisation getrennt werden. Nach dem neuen Verfahren werden somit aus zwei technisch vollkommen wertlosen Abfallprodukten mittels eines einfachen Prozesses drei Produkte von technischer Bedeutung hergestellt.It was now found that the ammonia salt easily and without impairment The zinc yield can be obtained by proceeding as follows: The ammonia slag barium sulfide is added in an aqueous solution in an equivalent to zinc Lot. Insoluble zinc sulfide is formed, which is filtered off and a solution of barium chloril and ammonium chloride. These two valuable products can get through fractional crystallization can be separated. According to the new procedure are thus from two technically completely worthless waste products by means of a simple one Process three products of technical importance are manufactured.
