Description

Verfahren zur Gewinnung von Nickel aus nickelhaltigen Hydrosilikaten. Im Hauptpatent ist für die Gewinnung von Nickel aus nickelhaltigen Hydrosilikaten, gegebenenfalls auch anderen nickelhaltigen Erzen, ein Verfahren angegeben, wonach das Erz zunächst bei hoher Temperatur unter Luftabschluß erhitzt wird und dann die Reduktion und Extraktion des Nickels erfolgt. Erfindungsgemäß läßt sich dieses Verfahren dahin abändern, daß bei Erhitzung auf die hohe Temperatur gleichzeitig auch die Reduktion vorgenommen wird. Während die fein gemahlene Erzmasse sich auf einer Temperatur von 500 bis tooo ° oder auch höher, zweckmäßig aber über 85o°, befindet, wird danach zur Durchführung der Reduktion beispielsweise Wassergas, Generatorgas oder Wasserstoff darüber geleitet. Es ergibt sich dann wieder metallisches Nickel, das aus der reduzierten Masse durch Behandlung mit Kohlenoxyd in der üblichen Weise, wie dies -im Hauptpatent näher erläutert ist, extrahiert werden kann.Process for the extraction of nickel from hydrosilicates containing nickel. The main patent is for the extraction of nickel from nickel-containing hydrosilicates, possibly also other nickel-containing ores, a method is specified according to which the ore is first heated at high temperature in the absence of air and then the Reduction and extraction of the nickel takes place. This method can be used according to the invention change so that when heated to the high temperature, the Reduction is made. While the finely ground ore mass is at one temperature from 500 to tooo ° or even higher, but expediently above 85o °, is then to carry out the reduction, for example, water gas, generator gas or hydrogen headed over it. It then results again metallic nickel, which from the reduced Mass by treatment with carbon dioxide in the usual way, as in the main patent is explained in more detail, can be extracted.
