Fatentirt im Deutschen Reiche vom 9. April 188a ab.Fatentirt in the German Empire from April 9, 188a.

Mein Verfahren bezieht sich auf die Gewinnung des Zinks bezw. der genannten Zinkverbindungen aus Erzen und Hüttenproducten, welche das Zink als Schwefelmetall oder als schwefelsaures Salz enthalten und welche zum Verschmelzen auf Zink zu geringhaltig sind.My process relates to the extraction of the zinc, respectively. of the zinc compounds mentioned from ores and metallurgical products which contain zinc as sulfur metal or as sulfuric acid salt and which for Melts on zinc are too low.

Die Zinkerze werden zunächst auf bekannte Weise in schwefelsaure Salze übergeführt, zerkleinert und mit Wasser bezw. verdünnter Schwefelsäure ausgelaugt. Die erhaltene wässerige Lösung von schwefelsaurem Zinkoxyd wird mit Magnesia in Form von Magnesiahydrat oder Aetzmagnesia oder mit kohlensaurer Magnesia versetzt. Im letzteren Falle resultirt kohlensaures Zinkoxyd als Niederschlag und schwefelsaure Magnesia geht in Lösung, im anderen Falle wird das Zink als Zinkoxyd gefällt und ebenfalls schwefelsaure Magnesia in Lösung erhalten. Der Zusatz von Magnesia oder von kohlensaurer Magnesia wird dem Zinkgehalt der Lösung entsprechend nach den Atomgewichten bestimmt.The zinc ores are first converted into sulfuric acid salts in a known manner, crushed and treated with water or water. leached dilute sulfuric acid. The resulting aqueous solution of sulfuric zinc oxide is mixed with magnesia in the form of hydrate magnesia or caustic magnesia or with magnesia carbonate. In the latter case, carbonic zinc oxide results as a precipitate and sulfuric magnesia dissolves; in the other case the zinc is precipitated as zinc oxide and sulfuric magnesia is likewise obtained in solution. The addition of magnesia or carbonate of magnesia is determined according to the zinc content of the solution according to the atomic weights.
