Application filed November 15, 1905- Sorial No. 287.466.

To @ZZ whom it may concern: A

Be it known that I, DAVID MoKELvEY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Amalgamators, of which the following is a specification.

The object of my invention is to provide an improved construction lof amalgamator which will operate efficiently to separate free gold from auriferous bearing material and which will thoroughly intermingle the gold with mercury under such pressure that all of the particles of the gold will effectl an amalgamation with the mercury.

More specifically, it is the object of my invention to rovide an improved amalgamator in which t e auriferous material as 1t is fed to the mercury bath will be caught by streams containing a solution or agent for destroying an slime that may be present in the pulp whic will subsequently by the action of other streams of water, steam, air, or gas or any similar agent drive the' pulp into the `mercury and' cause it to be thoroughly commingled with the mercury to form a high per cent. amalgam and which will finally discharge the pulp u wardly through. Whirlin streams, which l keep the side walls of the discharge-passage clear of pulp .after the gold has been extracted; and a further object ofthe invention is to provide an amalgamator of the essential characteristics above set forth with an im roved jacket for steam, hot air, or any hot quid or gas that will keep the mercury bath warm.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the 'means for effecting the result reference is to be had to the following description and accompanying drawin s, which- Figure 1 is a side e evation. Fig. 2 is a longitudinal section. Figs'. 3 and 4 are horizontal sections taken on different planes. Fig. 5 is an end elevation. Fig. 6 is a top plan view.

Corresponding and hke parts are referred to in the followin descriptlon and indicated in all the views o the drawings by the saine reference characters.

My improved amalgamator comprises a,

casting or suitable metallic. structure which may be made. in one, two, or any convenient 'v both the sluice-column andthe two pul discharge columns extending aipproximate y in a vertical direction and a of them at their lower ends communicating with a mercury-chamber 3, which is provided at its lower end with a draw-off port or passage 4. Preferably the structure in cross-section ta ers in a downward direction, so that theA p p-discharging columns 2 are contracted at their lower ends where' they meet the lower end of the sluice-column 1, and the walls of the datter are provided with an outwardlyextending iiange 5, thefunction of which will be described in connection with the other parts when the operation of the amalgamator is set forth. The sluice-column 1 is formed by a central hollow structure 6,`which, as shown, is of frusto-conical shape inverted and is hollow, so asl to provide upper and lower chambers 7 and 8, which are separated from each other by solid partition-walls as clearly shown in the drawings. In t ose. portions-,of the walls of the central structure 6 which constitute the upper chamber 7 are a plurality of ports or jets 9,l which open inwardly from the chamber 7 into the sluicecolumn near the upper end .of the latter. From the chamber y8 downwardly-extending jets or nozzles 11 extendin'to' the lower end of the sluice-column 1. The outer walls of the structure which boundl the two vertical pul -discharging columns 2 are provided wit independent or distinct upper and lower chambers 12, and at suitable points or intervals around said chambers 12 there are located non-radial outlet jets or openings 13. As best seen in Figs. 1 and 5, the upper chamber. 12 is provided with a boxing .15, havin inlet-openings 12a communicating with t e chamber, said boxing 15 also be.

provided with a middle section formed w1t an inlet-opening 17, designed to communileo cate with the interior of the chamber 7.

In a similar mannerthe boxing 1Q is provided for the lower chamber 1 2, said lower boxing-being also formed'with inlet-opentively. By this provision of separate boxings, as described, the supply of iluid to the respective chambers may be independently controlled. These independent inlet-openings for they respective chambers may be provided with globe-valves or other similar devices for the independent control.

The'p-uip is fed 1 into the amalgamator by means of the sluice-column 1. As it is admitted to the sluice 1 it is caught by streams containingasolution or agent for destroying any slime that maybe in it, said streams issuing out 'of the ports or' jets 9. Further on in the1 sluice the pulp meets other streams, which i are of water, steam, or any similar agent, is-

suing forcibly 'out of the jets or nozzles 11, and o to the Adownward deflection of said jets the pulp will be forciblyimpelled through the mercury which is in the chamber `3, preferably toa height just above the flange 5, and will be caused to thoroughly commingle with the Imercury to form the amalgam. The pulp' by means of itsrelative specific gravity 'will rise in' the side columns 2, and the flange z5 by its projecting location will prevent the pulp from hugging the interior walls of the apparatus when passing through the mercury. As the pulp after the gold has been extracted therefrom rises into the side columns 2 ity will be caught by whirling streams, which issue out ofthe two sets of "j ets or nozzles and owing vtoS the vlwhirlingy motion set up will be carrie'd upwardlyand out of the 'amalgamator without clinging to the vsides lof the same.

In order to' keep the mercury bath sufficiently warm,'I 'have provided a jacket 14, which fits around the bottom of theapparatus, be'ingsecured thereto by bolts or the like, and by its connection keeps the mercury sufficiently'warm by means of steam, hot air, or any other hot liquid or gas that may be used for the purpose.

lFrom the foregoingdescription, in connection with the accompanyin `drawings,v itwill be seen that I have provide .an amalgamator in which the pulp will be thoroughly treated toeifect'a separation of the gold therefrom.

: Having thus described the invention, what is claimedas new isl. An' amalgamator. provided with aV bottom"mercury-chamber and with upwardlydischarging vcolumns opening thereinto and 'with a 4central structure providing one' wall of said columns `and a vertical sluice-column between said side columns, said central structure being provided with upper and lower chambers'separated from each other, means for supplying, the' upper end of said sluice 'with 'a' slime-destroying agent-issuing' from easier' said upper chamber, downwardly-deflected jets or nozzles issuing yfrom the lower chamber of the sluice, and non-radial jets in said side columns.

2. An amalgamator provided with a bottom mercury-chamber and with upwardlydischarging columns opening thereinto-and with a central structure providing one-wall of said columns and a vertical sluice-column between said side columns, said central structure being provided with' upper and lower chambers separate from veach other, the upper chamber beingprovided with ports opening into the vsluice-column and the lower chamber being formed with downwardly-extending nozzles also opening into the-sluicecolumn near the bottom thereof, and means for supplying the said upper and lower chambers with iiuid independently. v

3. An amalgamator provided witha bottom mercury-chamber a 'discharge-column opening upwardly therefrom, and asluice with its 4lower end opening into the mercurychamber, and an upper .and a lower set of jets opening into saidsluice, the lower set of jets extending downwardly into the sluice and both sets of jets being arranged for independent control.

4. An' amalgamator providedfwithfa bottom mercury-chamber, a central sluice openingV thereinto and two upwardly-discharging slime-columns on op osite sides of said sluice and opening at their ower-ends int-o the mercury-chamber,- the amalgamator' being also providedwith upper and lower distinct chambers 12 providedwith non-'radial jetsopening into the slime-discharge columna-fand each chamber being designed for independent con nection to the source- Ofluid-Supply, and.
