Description

Verfahren zur Herstellung von Ammoniümsulfat, insbesondere für Düngezwecke Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Ammoniumsulfat, insbesondere für Düngezwecke, unter Umsetzen von Eisen-Sulfat mit Ammoniak unter Bildung von Eisenhydroxyd einerseits und Ammoniumsulfat anderersei.ts, zweckmäßig unter Wahl einer solche Ammoniakmenge gemäß der stöch.iometrischen Formel derart, daß das Eisenhydroxyd ausfällt und auf wertvolle Stoffe aufgearbeitet werden kann.Process for the production of ammonium sulphate, in particular for fertilization purposes The invention relates to a process for the production of ammonium sulfate, especially for fertilization purposes, reacting iron sulfate with ammonia under Formation of iron hydroxide on the one hand and ammonium sulfate on the other, expedient choosing such an amount of ammonia according to the stoichiometric formula such that that the iron hydroxide precipitates and can be worked up on valuable substances.

Es wurde nun gefunden, daß die Umsetzung mit Vorteil mit Eisensulfat durchgeführt wird, das bei anderen Verfahren als dem Beizen von Eisen anfällt. Als Abfallprodukt bzw. schwer verwendbares Nebenprodukt fällt Eisensulfat bei der Gewinnung von Titan bzw. Titanverbindungen und bei der Gewinnung von anderen Metallen, deren Erze Eisen enthalten und die unter Verwendung von Schwefelsäure aufgearbeitet werden, in großer Menge an. Die Verwendung von Eisensulfat, d. h. seine Nutzbarmachung, stieß einerseits auf große Schwierigkeiten und andererseits ist bei der Herstellung von Ammonium.sulfat die Ersparung von Schwefelsäure äußerst erwünscht. Beide Probleme werden gemäß der vorliegenden Erfindung gemeinsam gelöst, da sowohl dass Eisensulfat, das z. B. als Abfallprodukt bei der Herstellung von Titan, usw. anfällt, in. wertvolle Stoffe, d. h. Ammoniumsulfat einerseits und Eisenhydroxyd, das auf Eisenfarben, Eisen selbst oder Eisenverbindungen aufgearbeitet werden kann, andererseits übergeführt wird, als auch durch eine doppelte Umsetzung dieses Eisensulfats mit Ammoniak eine erhebliche Ersparnis an Schwefelsäure eintritt. Die in Form von Ammonium6ulfat als Düngemittel verwendete Schwefelsäure wird' infolge der doppelten Umsetzung-zweimal nacheinander nutzbar gemacht, einmal für die Gewinnung vonTitan und anderer Metalle, oder für die Gewinnung von Eisen aus Abbränden usw. und ohne Wiedergewinnung der Schwefelsäure als solche für die Bindung von Ammoniak, und Bildung von Ammoniumsulfat.It has now been found that the reaction is advantageously carried out with iron sulfate, which is obtained in processes other than iron pickling. As a waste product or by-product that is difficult to use, iron sulfate occurs in large quantities in the extraction of titanium or titanium compounds and in the extraction of other metals whose ores contain iron and which are processed using sulfuric acid. The use of iron sulfate, ie its utilization, encountered great difficulties on the one hand and, on the other hand, the saving of sulfuric acid in the production of ammonium sulfate is extremely desirable. Both problems are solved together according to the present invention, since both that iron sulfate, the z. B. as a waste product in the production of titanium, etc., in. Valuable substances, ie ammonium sulfate on the one hand and iron hydroxide, which can be worked up on iron colors, iron itself or iron compounds, on the other hand, as well as by a double conversion of this iron sulfate with Ammonia results in a considerable saving of sulfuric acid. The sulfuric acid used as fertilizer in the form of ammonium sulphate is' made usable twice in succession as a result of the double conversion, once for the extraction of titanium and other metals, or for the extraction of iron from burn-offs etc. and without recovering the sulfuric acid as such for binding of ammonia, and formation of ammonium sulfate.
