METHOD FOR THE REDUCTION, EXTRACTION AND SEPARATION OF METALS AND/OR METAL COMPOUNDS FROM METAL CONTAINING RAW MATERIALS

摘要

The specification describes a method for extracting metals of metal containing substances such as minerals and ores. A mixture of such substances with organic substances is produced. For each equivalent of metal one equivalent is made available in the organic substances of the reducing element and furthermore a sufficient quantity of organic substances is added in order to produce an exothermic reaction. The mixture is pressed to form particles or small bodies, which are introduced, at atmospheric temperature, into a high temperature zone, of at least 800.degree. C, so that an exothermic reaction ensues. This reaction leads to a rise in the temperature at least as far as the fusing point of the metal. The pellets are surrounded with a gas-imper-meable casing before introduction into the high temperature zone and after sharing.
