Verfahren zum Brikettieren von Metallabfällen und Erzen.Process for briquetting scrap metal and ores.

Patentiert im Deutschen Reiche vom 28. Februar 1904 ab. Patented in the German Empire on February 28, 1904.

Gegenstand vorliegender Erfindung ist ein Verfahren zum Brikettieren von Metallabfällen und gewissen Erzen, in erster Reihe von Metalloxyden und Hydroxyden, ferner von allen solchen Erzen, die mit einer Lösung der Sulfate der Erdalkalien, namentlich des Magnesiums und Calciums zusammengebracht, mit diesen eine Wechselzersetzung erleiden oder Doppelsulfate bilden.The present invention relates to a method for briquetting metal waste and certain ores, primarily metal oxides and hydroxides, and also all of them those ores which are obtained with a solution of the sulphates of the alkaline earths, especially of magnesium and calcium, undergo alternating decomposition with them or form double sulphates.

ίο Als Bindemittel wird eine schwache Lösung von Magnesiumsulfat benutzt, die auch etwas Calciumsulfat enthält, wie sie beim Zentrifugieren des Abfallschlammes von Dolomit verarbeitenden Kohlensäure- oder Sodawasserfabriken gewonnen wird.ίο As a binder is a weak solution of magnesium sulphate, which also contains some calcium sulphate, as it is when centrifuging the waste sludge from carbon dioxide or soda water factories that process dolomite is won.

Stehen die Abfallerzeugnisse der Kohlensäureindustie nicht oder nicht in genügender Menge zur Verfügung, so kann man selbstverständlich die Lösung so herstellen, daß man Dolomit mit Schwefelsäure zersetzt.Are the waste products of the carbon dioxide industry not available or not available in sufficient quantity, so one can of course prepare the solution by decomposing dolomite with sulfuric acid.

Von bekannten Brikettierverfahren, bei denen auch Sulfatlösungen benutzt werden, unterscheidet sich das vorliegende dadurch, daß einerseits sehr verdünnte Lösungen, andererseits, daß nur Erdalkaliensulfatlösungen verwendet werden. Die erhaltenen Briketts zeigen weder außen noch innen eine erhebliche Rostbildung, weshalb beim Einschmelzen das Metall fä*st vollständig in regulinischem Zustande gewonnen wird.From known briquetting processes in which sulphate solutions are also used, the present one differs in that on the one hand very dilute solutions, on the other hand, that only alkaline earth sulfate solutions are used. The briquettes obtained show no significant outside or inside Rust formation, which is why when the metal is melted down completely in regular State is won.

Die zu verarbeitenden Rohstoffe werden mit der stark verdünnten Flüssigkeit benetzt und dann zu Formstücken gepreßt.The raw materials to be processed are wetted with the highly diluted liquid and then pressed into shaped pieces.
