PENTEOOST J. MITCHELL, OF SALT LAKE CITY, UTAH TERRITORY, ASSIGNOR TO HIMSELF AND JOSEPH E. GAY, OF NEV YORK CITY.
IMPROVEMENT IN FURNACES FOR ROASTING ORES.
Specification forming part of Letters Patent No. 151,900, dated June 9, 1874; application filed May 16, 1874.
To all whom it may concern:
Beitknown that I,PENTECOST J. Mr'rorrnLL, of Salt Lake City, in the county of Salt Lake and Territory of Utah, have invented a new and improved oven for desulphurizing or call oining ores of iron, copper, silver, lead, and other ores or minerals carrying or containing iron pyrites, sulphur, arsenic, and other deleterious substances, of which the following is a specification Figure 1 is a plan view of the apparatus embodying my invention. Fig. 2 is a horizontal section of the same. Fig. 3 is a longitudinal section, and Fig. 4 is a transverse section.
Similar letters of reference indicate corresponding parts.
Iconstruct an oven of rectangular structure, of brick or other fire-proof material, of which N N are the side walls, and arrange thereon hoppers A, of cast or wrought iron, with a movable side, a, to be opened or closed by means of a shaft, 1, and chain Q. The ores or materials for calcination are placed within the hoppers, where they remain a few hours, when they are dropped through the action of the sliding doors upon the calcining-floor F F, which is constructed of cast-iron plates supported upon brick lines R B, through which the heat is conducted from the furnaces O O, and returned over the working-floor through the flue 0, re oeivin g an additional supply of heat from the furnaces D D. The smoke and impure gases are carried oil by the draft of the chimney K K K through the lines J J and the condensers L L, consisting of a showering or sprinkling apparatus, through which water is let fall, by which a portion of the escaping sulphur, arsenic, &c., are deposited in the pans M M and removed at pleasure. The ores or minerals in process of calcination are manipulated by workmen using hooks or rabbles for that purpose through the doors B B and I I. When it is sufiiciently prepared it is precipitated through the opening G into cooling-arch H H, from which it is transported to reduction-works. The letters E indicate the ash-pits to the furnaces (J O and D D.
The object of my invention is toexpel, by means of heat, sulphur, arsenic, and other deleterious substances usually found in nature, associated and combined with ores of iron, silver, copper, lead, and other ores or minerals, by reason of which they are comparatively valueless until removed.
Having thus described my invention, I claim as new and desire to secure by Letters Patent A desulphurizing-oven comprising the adjustable hoppers A, floor F, flues R, O, and J, furnaces U l), and condensing apparatus L M, combined and arranged substantially as specified.
PENTECOST J. MITCHELL.
