No. 12901.—22nd August, 1900.—CHARLES HARRISON WARD, of 60, Queen Street, Melbourne, Victoria, Metallurgist. An improved process of and furnace for chloridizing or for drying or roasting ores or other metalliferous materials, and (or) volatilising and separating their constituents.*

Claims.—(1.) An improved process of chloridizing or of drying or roasting ores or other metalliferous materials, and volatilising and separating their constituents, consisting in subjecting them in a furnace to the action of a pulsating or intermittent current of air or gas passing through the hearth, then drawing off the vaporised constituents successively through one or more independent exits according to their respective volatilising-points, substantially as and for the purposes described and explained. (2.) Subjecting ores or other metalliferous material in a furnace to the action of a pulsating or intermittent current of air and (or) gas passed through the hearth, substantially as and for the purposes specified. (3.) In a furnace for chloridizing or for drying or roasting ores or other metalliferous materials, and (or) volatilising and separating their constituents, an adjustable shaking or vibrating hearth, in combination with means for supplying air and (or) gas therethrough to the material under treatment, substantially as and for the purposes specified, and as illustrated in the drawings. (4.) In a furnace for chloridizing or for drying or roasting ores or other metalliferous materials, and (or) volatilising and separating their constituents, a hearth having numerous air- or gas-supply ports or passages, as b, arranged approximately horizontally or at only a slight incline through said hearth, and with or without baffles as b', substantially as and for the purposes specified, and as illustrated in the drawings. (5.) In a furnace for chloridizing or for drying, roasting, and (or) volatilising and separating metals and (or) other materials in ores and ore-concentrates, a hearth whose surface consists of a series of shallow steps, with a number of approximately horizontal holes or passages allowing the passage of air and (or) gas from air-chambers d through the “risers” of said steps, and either with or without baffles or deflectors, as b', near the discharge-ends of said holes or passages, substantially as and for the purposes specified, and illustrated in Fig. 4 of the drawings. (6.) In a furnace for chloridizing or for drying or roasting ores or other metalliferous materials, and (or) volatilising and separating their constituents, the combination with a hearth having numerous air- or gas-supply ports or passages, as b, arranged approximately horizontally or at a slight incline therethrough, of practically air-tight chambers, as d, arranged beneath the hearth and communicating with the perforations or passages in separate sections thereof, substantially as and for the purposes specified, and as illustrated in the drawings. (7.) In a furnace for chloridizing or for drying or roasting ores or other metalliferous materials, and (or) volatilising and separating their constituents, a hearth having numerous air- or gas-supply ports or passages, as b, arranged approximately horizontally or at only a slight incline therethrough, said hearth being suspended or supported so that its inclination can be adjusted, and so that it can be vibrated or shaken, said hearth being connected by a pipe or pipes having ball-and-socket and telescopic joints with an air- or gas-supply pipe whereby a current of air or gas, preferably pulsating or intermittent, may be supplied to the material under treatment, substantially as and for the purposes specified, and as illustrated in the drawings. (8.) In a furnace for chloridizing or for drying or roasting ores or other metalliferous materials, and (or) volatilising and separating their constituents, the combination with a hearth having an air- or gas-supply thereto of partitions extending through the furnace roof or sides so as to practically divide the furnace into a number of chambers or compartments each having a separate exit or exits, substantially as and for the purposes specified, and as illustrated in the drawings. (9.) In a furnace for chloridizing or for drying or roasting ores or other metalliferous materials, and (or) volatilising and separating their constituents, a rotating hearth having air- or gas-supply perforations or passages so
