Abstract
In the production of zinc oxide by blowing air through a shallow charge consisting of a mixture of coal and zinc or lead-zinc ore or the like on a bed of ignited fuel on a fixed grate of large area, the ignition fuel or the ore or the reducing coal is used in the form of briquettes, for instance of double pyramidal form on a common square base of 1 3/4 inch side, the distance between the apexes being 1 1/2 inches; or the ore and reducing fuel may be briquetted together, and some ore may be briquetted with the ignition fuel. The binding agent may be sulphite cellulose liquor and a pressure of 2000 lb. per square inch may be used in the briquetting. The briquettes are dried and baked by stacking on trays in a tunnel drier at 200 DEG C. The pressure of the blast is less than in the known process, and it may sometimes be dispensed with, the fan which draws the fume through the bag room being sufficient to draw enough air through the charge.
