IMPROVED APPARATUS FOR TREATING ORES WITH CHLORINE.

Speciication forming part of Letters Patent No. 56,549, dated July 24, 1866; antedated July 11, 1866.

To all whom 'it may concern:

Be it known that I, EUGENE GAUssoTN, of the city and county of Baltimore, and State of Maryland, have made new and useful Improvements in the Treatment oi' Gold Ore by Chlorine 5 and I do hereby declare the following to be afull, clear, and exact description of the nature, construction, and operation of the same, sufiicient to enable one skilled in the art to which it appertains to construct and use the same, reference being had to the accompanying drawings, which form part of this specification, and in which- Figure 1 is a vertical section on the line z e, Fig. 4. Fig. 2 is a vertical section transversely of the axes of the barrels and on the line w x, Fig. 4. Fig. 3 is a vertical section on the line yy, Fig. 4. Fig. 4 is a plan or top view.

The object of the invention is to obviate the practical difficulties attending the operation on large quantities of ores by such devices as those in which the gas is introduced through false bottoms, wherein the ores require to be agitated and stirred up to subject them completely to the action of the gas.

The invention is also designed to prevent the exposure of the workmen to the deleterious action of the gas by confining the barrels in which it operates within a casing or structure, through openings in which the orifices of the chambers are reached to renew and discharge the contents, and through passages in which the gas is introduced and withdrawn, according to the requirements of the process.

In the drawings, Ais the central longitudinal wall, and B the central transverse wall, parallel to the latter, being the end walls, O O, which support the hollow journals D D of the barrels E, which rotate within the chambers formed by the said walls and the arched doors F.

Each pair of barrels, as shown in Fig. l, are united by a hollow connectingjournal, I, and the end journals communicate by openings with channels M in the walls C B, by which the chlorine gas generated in the retort or ch amber X is conveyed from one story to another of the apparatus.

The barrels are not peculiar in their construction. They are represented as of the ordinary bilge shape, with heads strengthened by disks to which the hollow journals are attached, and the gas passes from one series to another in the manner described.

Each barrel is provided with an opening, J, at its bilge, closed by a lid or cover, L, and the charging is done from the top through the openings R, which, when the upper series of barrels are rotated to the right position, aftbrds the, means for the introduction of the ore into the barrels. To change the series next below, the upper set are rotated one-half a revolution, which brings their respective openings opposite to each other, when, the lid being slipped back, the ore falls into the barrel below. This process is repeated to charge the set next in series below, and the simultaneous action of the barrel is secured by ymeans of connecting them all to a common set of gear-wheels and shafts, S S T.

The passages M in the end wall, O, pass up- 'wardly and discharge at M, Fig. 4, while the middle wall is pierced with sevensix of which (marked N, Figs. 3 and 4) lead from the middle journal-bearings of the six pairs of barrels, while the middle shaft, W, communicates by the drains Y with the chambers in which the barrel rotates, so as to remove from them any drip from the barrels.

The arched oors between the chambers have openings I, which admit of the discharge from one to another when the valve K is withdrawn and the openings in the barrels relatively adjusted.

The shape of the sliding lids L prevents any drip from the barrels passing through the opening L below it, and the collected drainage from Y Y WV is collected and carried oft' to the laboratory. e

The discharging is commenced at the lower barrel into a vessel in the chamber Z, and the ,openings H in the side walls give access to the covers of the barrels when required.

When the barrels are charged and closed the gas is admitted through the hollow axles and the passages in the walls from barrel to barrel, while the latter revolve to expose every particle of ore to the iniiuence of the gas, the surplus of which escapes at the top at the orices M N, to be concentrated in a proper apparatus.

After revolving the necessary time with chlorine, hot water is introduced into the barrels by the pipes M N N, and the barrels revolve again to dissolve the chlorides, the free chlorine being also absorbed by the hot water, so as not to be inhaled by the workman at the openings H, who manipulates the doors L when about to discharge the contents of the barrels.

The superabnndant chlorine may be exhausted by pumps from the apparatus, if required.

In discharging, the fluids are, by the valves K, turned into the channels Y Y W, which proceed to the laboratory, when, in the case of gold solutions, the precipitation is eff'ected by sulphate of iron or other chemical process. The impoverished ore is then discharged into the chamber Z.

The insides of the hollow axles are protected against the action of the gas by a lining of gutta-percha, varnish, or other suitable substance.

In some cases I use ellipsoids in the barrels to assist in the trituration of the amalgam.

Having described my invention, whatI claim therein as new, and desire to secure by Letters Patent, is-

l. The inclosing walls andoor, forming chambers in which the barrels revolve, and

from which the fluid contents are removed by drains from the sides and the solid by an aperture at the corner of the arch.

2. The combination ofthe hollow axles and perforated walls, forming a series of connections from the generator', from barrel to barrel, and ultimately to the discharge-apertures at the summit.

3. The arrangement of the barrels with their operating-gearing, so that their respective openin gs are in revolution presented alternately to the openin gs ofthe ones next in series above and next below, to afford the means of discharging, as described.

4. The combination of the revolving barrels and the openings J and wall-openings H, as and for the purpose described.

5. The combination of the valves K with the drains Y Y W, as and for the purpose de-v
