   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.

 it has been shown that this procedure can be considerably simplified in the last working studies.



   The modified ancestor works in the following way:
The first work 1. Stone melting, 2. Sulphating roasting, 3. Laugercim with acidic water and 4. Return of the caustic residue to the melting process.

   7. The nickel sulfate solution is evaporated, if necessary after purification of iron and cobalt, and allowed to cool to crystallize, with nickel vitriol and a mother-

   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
