  Process for the production of iron sulfate from gravel burns.
 EMI1.1
 Hydrogenated sulfuric acid, even if the latter is present in excess, is heated to red heat, iron sesquioxide of the well-known bright red color is not obtained.
 EMI1.2
 The brownish-violet iron compounds in the ashes are dark brown-violet.



     In view of the fact that these products have hitherto been restricted to the manufacture of low-quality materials in industry, it has hitherto not been considered worth the trouble to subject the same special cleaning processes.
 EMI1.3
 of ferrous sulfate, the commercial value of which more than outweighs the cost of the above treatment.



   The consumption of the acid is proportional to the iron content of the gravel burns and there

 can be.

PATENT-ANSPRUCH : Verfahren zur Herstellung von Eissensulfat aus Kiesabbränden unter gleichzeitiger Abscheidung des eventuell in denselben vorhandenen Kupfers, dadurch gekennzeichnet, dass man die Kiesabbräude mit ca. 2% Kohle in einem Apparate erhitzt, der gestattet, das Gemisch nnter Luftabschluss orkalten zu lassen, dann nach dem Erkalten die nunmehr magnetisch gewordenen Teile dureh einen magnetischen Erzscheider abtrennt, dieselben in bekannter Weise in Schwefelsäure löst, und die so erhaltene saure Lösung mit. metallischen Eisen behandelt. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Process for the production of iron sulfate from gravel burns with simultaneous deposition of any copper present in the same, characterized in that the gravel chips are heated with approx. 2% coal in an apparatus which allows the mixture to cool in the absence of air, then after cooling the parts that have now become magnetic are separated by a magnetic ore separator, dissolve them in a known manner in sulfuric acid, and the acidic solution thus obtained with it. metallic iron treated. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
