Abstract
The ratio of water-soluble cadmium to zinc values is increased in dusts recovered in the heating of zinciferous materials, these dusts containing water-insoluble oxidic cadmium compounds and zinc sulphate, by heating the dust, at a temperature from 400-700 DEG C., to form cadmium sulphate and zinc oxide. If there is insufficient zinc sulphate to convert all the cadmium to sulphate, zinc sulphate may be added. After this first heat treatment, the material may be heated to above 700 DEG C. (decomposition temperature of zinc sulphate) and below 827 DEG C. (decomposition temperature of cadmium sulphate) to convert any remaining zinc sulphate to the oxide. The product may be leached to recover the cadmium sulphate. Any ferric sulphate present in the original dust is converted to the oxide by the heating. Copper, aluminium, and arsenic are also rendered insoluble.
