Description

Verfahren zur Gewinnung von Nickel aus nickelhaltigen Hydrosilikaten. Im Hauptpatent ist ein Verfahren angegeben, durch das es ermöglicht werden soll, aus nickelhaltigen Hydrosilikaten, gegebenenfalls auch anderen nickelhaltigen Erzen, das Nickel zu gewinnen. Die feingemahlene Erzmasse wird dabei einem Reduktionsprozesse unterworfen und das in der reduzierten Masse enthaltene metallische Nickel durch Behandlung mit Kohlenoxyd extrahiert. Statt dessen ist in früheren Zusatzpatenten bereits angegeben worden, die Extraktion des Nickels dadurch zu bewerkstelligen, daß es mittels Schwefelsäure oder Ammoniakwassers in Lösung gebracht wird. Insbesondere ist die Extraktion erschwert, wenn neben dem metallischen Nickel in der reduzierten Masse auch noch metallisches Eisen vorhanden ist.Process for the extraction of nickel from hydrosilicates containing nickel. The main patent specifies a method by means of which it is to be made possible from nickel-containing hydrosilicates, possibly also other nickel-containing ores, to win the nickel. The finely ground ore mass is used in a reduction process and the metallic nickel contained in the reduced mass through Treatment with carbon dioxide extracted. Instead, it is in previous additional patents has already been stated to accomplish the extraction of the nickel by that it is brought into solution by means of sulfuric acid or ammonia water. In particular the extraction is more difficult if in addition to the metallic nickel in the reduced There is also metallic iron present.

Gemäß der Erfindung soll nun in diesen Falle eine Extraktion überhaupt nicht vorgenommen werden. Die das Nickel und Eisen enthaltende Reduktionsmasse wird vielmehr einem Schmelzprozesse unterworfen, um auf diesem Wege ein Nickel-Eisenkonzentrat zu erhalten. Für den Schmelzprozeß wird dabei zweckmäßig ein elektrischer Ofen vom Heroulttyp benutzt.According to the invention, in this case an extraction should take place at all not be made. The reducing mass containing the nickel and iron is rather, it is subjected to a melting process to produce a nickel-iron concentrate to obtain. For the melting process, an electric furnace is expedient Heroult type used.

Dieses neue Verfahren bedeutet dem bekannten gegenüber durch den Wegfall des immerhin kostspieligen Extraktionsprozesses eine wesentliche Verbilligung. Das erhaltene Nickel-Eisen-Konzentrat ist dabei für die Stahlindustrie wertvoll und kann dort unmittelbar verwendet werden.This new process means that the familiar is no longer available the at least costly extraction process is a significant reduction in price. That The nickel-iron concentrate obtained is valuable for the steel industry and can be used there immediately.

Bei der Reduktion der Erzmasse kann es empfehlenswert sein, daß ein gewisser Zusatz von Kohlenstoff gegeben wird.When reducing the ore mass, it may be advisable that a some addition of carbon is given.
