Abstract

1389282 Metallic oxides, chlorides &c. LARCO SOC MINIERE ET METALLURGIQUE DE LARYMNA SA 9 Feb 1972 [11 Feb 1971] 6108/72 Heading C1A A method of production, in very pure form, of the oxides and/or chlorides of metals of the group comprising Al, Be, Bi, Co, Cu, Pb, Fe, Ni, Zn, or production of the metals themselves, from alloys or scrap metal containing at least two of the above mentioned metals, comprises the following steps in a closed cycle process: (i) a chlorination step to produce gaseous metal chlorides, by reaction with hydrogen chloride gas, (ii) a condensation step to separate out one or more of the volatilized chlorides followed by either (III) an oxidation step with water vapour to form the metallic oxide or (iv) a reduction step with hydrogen to form the pure metal, unconverted chlorides, metals or metal oxides not withdrawn from the system free HCl and unused water and/or hydrogen being recycled to the chlorination chamber. A temperature of about 850‹ C. is maintained in the chlorination chamber. The speed of chlorination may be increased or maintained at a set value by addition of granules of metals very reactive to chlorine such as Fe, Al. Alternatively, other elements such as C, S, As, Si and P may be introduced for this purpose. The apparatus used is the same as that of application 6109/72 with the difference that the reducing chambers and collecting hoppers are omitted, the gases leaving the oxidizing and reducing chambers being vented.
