APPARATUS FOR SEPARATING SULFUR FROM ORES.

SPECIFICATION forming part of Letters Patent No. 635,574, dated October 24, 1899.

- 1 Application filed February 24, 1897. Serial No. 624,776. (No model.) I

T0 on whom it may concern:

Be it known that 1, JAMES B. McCABE, of Bufialo, in the county of Erie and State of New York, have invented a new and Improved Apparatus for Separating Sulfur from Ores, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new andim proved apparatus for treating ores containing sulphur, to separate the latter from the precious metals, notably gold, in a very simple and economical manner.

The invention consists in an apparatus of special construction and hereinafter more fully shown and described, and pointed out in the claims.

Reference is to be had to the accompanying drawing, forming a part of this specification, in which the figure represents a sectional side elevation of the apparatus.

The improved apparatus shown in the drawing is provided with a suitably-constructed boiler A, supporting at its bottom a dischargepipe B, having a valve B, which is opened from time to time to discharge the liquid sulphur from the boiler A, as hereinafter more fully described. Within the boiler Aand separated from the walls thereof is arranged-a cylinder 0, having its rim formed of a perforated material, so as to act as a sieve. The solid heads of the cylinder are fastened to a shaft D, journaled in suitable bearings E, se-

cured to the ends of the boiler A, as shown. One end of the shaft D is made hollow, as atD, to form an inlet for the ore to be treated, the

. outer end of this part of the shaft being provided with a valve D and a feed-hopper F.

Y The inner end of this hollow portion of the shaft opens into the cylinder C, so that the material to be treated and fed into the hop} perF passes directlyinto the cylinder 0. The other end D of the shaft D is likewise made hollow, but is separated from the end D, and a branch pipe D extends from the inner end of the hollow shaft D to within a short distance of the rim of the cylinder 0. The outer end of this shaft part D is provided with a valve D and carries a pulley G, connected by a belt with suitable machinery for imparting a rotary motion to the shaft D and to the cylinder 0, carried by the said shaft. Into one end of the boiler A leads a water-supply pipe H, connected with a suitable water-supply, and a steam-pipe I, connected with a suitable steam-supply, so that the boiler A of the cylinder O can be completely filled with water and heated by the steam entering the boiler by the pipe I. As the water is confined within the said boiler it can be readily heated, say, up to 350, to insure the ready melting of the sulphur contained in the ore introduced into the cylinder 0 through the hollow shaft end D previously mentioned.

Now it is evident that the material passed into the cylinder 0 can be subjected to a rolling motion by revolving the cylinder, so that the said material comes in contactvwith the heated water to cause a complete melting of all the sulphur contained in the ore. The agitation of the ore not only facilitates the separation of the sulphur from the ore by bringing the particles thereof into contact with" the heated liquid, but it also prevents the melted sulphur from forming into pools in the mass of ore, and thereby causes a complete separation of the sulphur from the ore. As soon as the sulphur is meltedit passes through the meshes of the cylinder-rim, owing to the sulphur being of a higher specific gravity than the water, and flows to and settles in the bottom of the boiler A, to be discharged therefrom from time to time through the outlet-pipe B. The material, freed from the sulphur,can be readilydischarged through additional pressure may be supplied through the steam-pipe J, having a valve J and connected with a suitable source of steam-supply. The boiler A is also provided with the usual safety-valve K and pressure-gage L,

' thermometer N, and Water-gage O to indicate the height of the water in the boiler, the teinperature of the water, and the pressure thereof.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. An apparatus for separating sulphur from ores, comprising a boiler adapted to contain a heated liquid, and a perforated ore-cylinder mounted to revolve in the boiler and having hollow trunnions forming inlet and outlet, the outlet-trunnion extending nearly to the center of the cylinder and having a lateral outlet, substantially as described.

2. An apparatus for separating sulphur from ores, comprising a boiler adapted to contain a highly-heated liquid, and a revoluble perforated cylinder having a discharge-outlet extending inwardly to about the transverse center of the cylinder and then laterally toward the rim of the said cylinder, substantially as and for the purpose set forth.

3. An apparatus for separating sulphur from ores, comprising a boiler adapted to contain a heated liquid, a revoluble perforated ore-cylinder mounted in the boiler and having hollow trunnions, one of which serves as an inlet and the other as an outlet, and a pipe leading from the said outlet to within a short distance of the rim of the cylinder, substantially as described.

4. An apparatus for separating sulphur from ores, comprising a boiler provided with an outlet in its bottom, a revoluble perforated ore-cylinder mounted in the boiler, an oreinlet projecting into one end of the cylinder, and an angular outlet leading from the other end of said cylinder, the vertical member of said outlet extending nearly to the rim of the cylinder, substantially as described.

5. In an apparatus for separating sulphur from ores, the combination with a barrelshaped boiler having a discharge-opening in its bottom at about the center, of a barrelshaped cylinder having a perforated rim and hollow trunnions by which it is mounted in the boiler, one of the trunnions serving as an inlet and the other as an outlet, and a pipe leading from the outlet to within a short distance of the rim of the cylinder, substantially as described.

6. In an apparatus for separating sulphur from ores, the combination with a boiler having a discharge-opening in its bottom, a shaft mounted in the boiler and having hollow ends projecting out through the ends of the boiler, a cylinder secured to the shaft and having a perforated rim, and a pipe secured to the shaft and communicating with one of the hollow ends thereof,sa-id pipe extending to within a short distance of the rim of the cylinder, substantially as herein shown and described.
