Description

Verfahren zur Ausnutzung basischer Phosphatschlacken. Nach dem Verfahren des Patents 256303 nebst Z,usatzgatent 2587o9 werden die basischen: Phosphatschlacken in der Weise verwertet, daß einerseits der düngende Bestandteil und anderseits die im Eisenhüttenbetrieb wieder verwendbaren Eisen- und Manganverbind engen wiedergewonnen werden.Process for utilizing basic phosphate slags. According to the process of patent 256303 together with Z, additional patent 2587o9, the basic: phosphate slags are used in such a way that, on the one hand, the fertilizing component and, on the other hand, the iron and manganese compounds that can be reused in the ironworks are recovered.

Das vorliegende Verfahren bezweckt die gleichzeitige Gewinnung der neben den genannten Bestandteilen in kleineren Mengen in den Thomasschlacken vorhandenen Vanadiumverbi.ndungen, welche bei dem obigen Verfahren unbeachtet geblieben waren. Versuche haben ergeben,_ daß dieselben bei der Behandlung nach obigem Patent in dem; düngenden Bestandteil sich wiederfinden und durch fraktioniertes Erhitzen davon getrennt werden können.The present process aims to simultaneously obtain the in addition to the components mentioned in smaller quantities in the Thomas slag Vanadium compounds, which were ignored in the above process. Tests have shown that the same in the treatment according to the above patent in to the; fertilizing constituent can be found again and by fractional heating of it can be separated.

Zur Ausführung des Verfahrens werden die durch Behandeln, mit verdünnter Säurelösung erhaltenen, von den Eisen und Manganverbindungen getrennten, schwach sauren Phosphatlösungen erhitzt. Die Vanadiumverbindungen befinden sich in den: ersten beim Kochten sich bildenden Ausscheidungen. Bei richtig bemessenem Säuregrad scheiden sich dieselben schon beim Erhitzen aus vor dem Eintritt der Kochtemperatur. Nach deren Abscheidung wird das Erhitzen unterbrochen, die Lösung von dem Niederschlag getrennt und- bis zur Ausscheidung des Phosphats, welche sich unter Entwicklung von schwefliger Säure vollzieht, weitergekocht.To carry out the process, the treatment is carried out with diluted Acid solution obtained, separated from the iron and manganese compounds, weak heated acidic phosphate solutions. The vanadium compounds are in the: first excretions formed during boiling. With the correct degree of acidity They are separated out on heating before the temperature reaches the boiling point. After their deposition, the heating is interrupted and the solution is removed from the precipitate separated and up to the excretion of the phosphate, which is under development of sulphurous acid, continue to cook.

Die Vanadiumniederschläge werden auf bekannte Weise auf V anadium oder dessen Verbindungen verarbeitet.The vanadium precipitates become vanadium in a known manner or its connections processed.
