Die Voreinfachnng des Verfahrens wird noch klarer bei einem Vergleich des nachstehend angegebenen Arbeitsschemas mit der Übersicht des Verfahrens gemäss dem Stammpatente. Wenn der Nickelvitriol zu Nickeloxydul, Schwefelsäure und Schwefel- trioxyd zersetzt wird, statt ihn nach dem Hauptverfahren mit Sulfiden zu fällen, werden die Herstellung des Fällungsmittels (Schwefelnatrium), der K : i) ksteinzuschlag und die Entstehung eines Abfallproduktes (Gips) vermieden.

The preliminary simplification of the process becomes even clearer when comparing the working scheme given below with the overview of the process according to the parent patent. If the nickel vitriol is decomposed into nickel oxide, sulfuric acid and sulfur trioxide, instead of precipitating it using the main process with sulphides, the production of the precipitant (sodium sulphide), the K: i) stone aggregate and the creation of a waste product (gypsum) are avoided. But acidic gases are obtained which, on the one hand, have suifatisiori roasting, and on the other hand
