摘要： A process and apparatus for extraction of zinc from a material containing one or more iron oxides and zinc oxide which facilitate heating a composite body of the material and a carbonaceous material in a reduction zone. The reduction zone contains a reducing atmosphere at a temperature insufficient to effect melting of the iron in the material but at a temperature and for a time sufficient to form a reductant from the carbonaceous material and to reduce a predetermined amount of the zinc oxide to zinc vapour. The process and apparatus also facilitate collecting the zinc vapour and cooling it to form liquefied or solid zinc.

摘要： A cavity former (10) for forming one or more cavities in a concrete slab, includes a hollow body about which, during use of the former, poured concrete flows and subsequently cures to form a concrete slab in which the hollow body defines a cavity. A plurality of flanges (20, 21) projects from at least two sides of the body to define floors for respective channels adjacent the sides of the body. A plurality of supports (50, 51, 52 and 53) is integrated with and outstanding from the hollow body and/or flanges to support reinforcement mesh above the body and elongated slab reinforcement in the channels. Respective co-operable formations are disposed on the flanges and respective further sides of the body whereby respective pairs of the cavity formers may be located and relatively positioned together by the formations with one cavity former resting on a flange of the other, whereby to define the channels, which channels receive the poured concrete. Also disclosed is means for defining a seat in the hollow body for an object to project above the hollow body by a height that defines the top of the slab.
