Abstract: The method and the device serve to treat the flue dust formed during the production of nonferrous metals. After the addition of sulfur and/or a sulfur compound, the flue dust is heated, and volatile compounds are separated in a downstream offgas treatment unit. The flue dust is heated in an inert atmosphere.

Abstract: There is provided a method for recovering a powder of a compound of iron and arsenic, which has a very low concentration of arsenic eluted from the powder, by treating an arsenic containing solution, e.g., a high purity and high concentration arsenic containing solution obtained by treating an arsenic containing substance which contains various elements other than arsenic, such as an intermediate product in a non-ferrous metal smelting or refining process. Ferrous ions are added to an arsenic containing solution, which contains 10 g/L or more of arsenic, so as to cause the ratio (Fe/As) of iron to arsenic in the solution to be not less than 1, and an oxidizing agent is added to the solution to allow a reaction at a temperature of not lower than 70° C. while stirring the solution. Then, a solid-liquid separation is carried out, and a solid part separated by the solid-liquid separation is dried.

Abstract: The present invention is directed to an apparatus and method for recovering the group III elemental component of a group III-V material waste material. The method includes heating, under a reduced pressure, solid waste materials which contain group III-V material to cause the group III-V material to separate into a group III element and a group V element vapor; drawing off the group V element vapor; condensing the group V element vapor to produce a condensed group V element solid; and zone refining the group III element to produce a purified group III element. The apparatus is designed to carry out this method in the plant which manufactures the group III-V waste material.
