Description

Verfahren zur Herstellung von Ferrokobalt Die Erfindung betrifft ein Verfahren zur Verhüttung von Kobaltoxyd, insbesondere aus der Blaufarbenindustrie, von kobalthaltigen Erzen sowie von Rückständen, die Kobalt enthalten, und zwar in Form feiner Granalien oder solcher, die an andere Mineralien gebunden sind, wobei die Ausgangsstoffe gegebenenfalls durch vorbereitende Arbeiten in Kobaltoxyde übergeführt werden.Method for the production of ferrocobalt The invention relates to a Process for smelting cobalt oxide, especially from the blue paint industry, of cobalt-containing ores and residues containing cobalt in Form of fine granules or those bound to other minerals, whereby If necessary, the starting materials are converted into cobalt oxides by preparatory work will.

Es ist bekannt, Schwefelnickel oder Rohnickel bzw. Kobalt zu verarbeiten, indem Nickel oder Kobaltstein zwei Reaktionen unterworfen wird: i. Ausscheiden des Eisens durch Oxydation und Auflösung des Eisenoxyds in besonderen basischen oder alkalischen Zusatzmitteln, z. B. Salzen des Kaliums und Natriums, Aluminiums, oder borsaurem Kalk.It is known to process sulfur-nickel or raw nickel or cobalt, by subjecting nickel or cobalt stone to two reactions: i. Elimination of the Iron by oxidation and dissolution of the iron oxide in particular basic or alkaline additives, e.g. B. salts of potassium and sodium, aluminum, or borate lime.

z. Ausscheiden des Schwefels durch Anwendung bestimmter, ebenfalls basischer oder alkalischer Stoffe im Gemenge mit Chlorverbindungen derselben Natur.z. Excretion of the sulfur by applying certain, likewise of basic or alkaline substances mixed with chlorine compounds of the same nature.

Weiter ist ein Verfahren zur Gewinnung von Nickel oder Eisennickellegierungen aus nickelhaltigem Walzensinter, Hammerschlag und ähnlichen Eisenoxydnickelverbindungen bekannt, bei welchem die nickelhaltigen Stoffe mit Eisen in fester oder flüssiger Form niedergeschmolzen werden. Das Neue der Erfindung besteht darin, daB das kobalthaltige Gut, z. B. Kobaltoxyd, Erze oder Zwischenprodukte, wobei die letzteren vor der Verhüttung gegebenenfalls durch vorbereitende Arbeiten in Kobaltoxyde übergeführt werden, in flüssiges Eisen gebracht oder mit Eisen niedergeschmolzen wird.Next is a process for the production of nickel or iron-nickel alloys made of nickel-containing roll sinter, hammer blow and similar iron oxide nickel compounds known in which the nickel-containing substances with iron in solid or liquid Shape to be melted down. The novelty of the invention is that the cobalt-containing Good z. B. cobalt oxide, ores or intermediates, the latter before smelting possibly converted into cobalt oxides by preparatory work, in liquid iron is brought or melted down with iron.

Das Verfahren wird so durchgeführt, daB in einem Herdo#en Eisen geschmolzen wird, worauf die erwähnten kobalthaltigen Stoffe zugesetzt werden. Das Eisen reduziert die Kobaltoxyde und verbindet sich mit dem Eisen zu Ferrokobalt.The procedure is carried out in such a way that iron is melted in a stove whereupon the cobalt-containing substances mentioned are added. The iron reduced the cobalt oxides and combines with the iron to form ferro-cobalt.

Auch können die kdbalthaltigen Stoffe mit Eisen z. B. im Kupolofen niedergeschmolzen werden.The kdbalthaltigen substances can also with iron z. B. in the cupola furnace be melted down.
