COMBINED} SPREADER, l CONCENTRATOR, AND ,AMALGAMATOR.

fornia, have invented new and useful lImprovements in Combined Spreader-Sp Concentrators, and Amalgamators, of which the following is a specification.I

The present invention relates to pulp treating apparatus, and particularly to a combined spreading, concentrating; and amalgamating apparatus.

The object ofthe present lnvention is to provide a pulpdistributer, adaptable for cooperation with1 a concentrating, machine;

the distributer involving means for spreading the pulp, means for amalgamating free gold, or other amalgamablemetal, and to concentrate a part of the pulp from thetailings before the pulp ;is delivered to the subsequent concentrating machine. a

The invention consists of an apparatus adapted for cooperation with an, amalgaa movement to produce a pan+like action, upon: the structure 2,wh1ch as mounted thereon,

mating machine, having lateral I or orbital movement, wherein the pulp being handled can be evenly: spread, concentrated and partly amalgamated} a a 1 a Figure 1 is a central, vertical section through the apparatus as applied to a concentrating machine. a F ig, 2 :is aa detail plan view a showing staggering plates. 1'

My present invention comprises a tank,

box, or other structure2, of suitableilength, width and depthwwhich is adapted to be mounted upon1 a 1 concentrating machine, a, portion of theframe of which 1s indlcated at 3, and over which runs a belt lJmoving upwardly in a slightly inclined plane.

The concentrating machine, including the frame and belt, preferably has an orbital so that pulp fed in from a pipe 5 will, when deposited upon an inclined plate 6, flow downwardly toward and :against staggering plates 7 which project upwardly fromithe plate 6; the latter terminatingsomewhat short of one of the ends of the box 2,,the pulp falling over the discharge end 8 i of the plate onto a diaphragm or plate 9 which is inclined downwardly and oppositely to the plate 6, so th t the water and pulp falling to the plate Iwillifio-wtoward the rear end 10 of the box which is providediwith a plurality of regulating, gates 111,3 covering apertures 12 through which water andpulp Specification ofiLetters Patent.

maydischarge onto an apron 13 projecting i from the rear end of the box, and havingva depression or riflie 14: for the purpose of f collecting suchlheavy articles or concentrates ]ion the pulp as may have escaped from the Near the lower end 30f theconcentratinga plate 9 is provided a discharge opening115,1- through which the concentrates settling; on 5 the plate 19 will discharge onto theibottom a 16 of the box, which preferably is provided 1 with a copper plate mercury coated, so that; 1 as particles ofgold and other material flow down, the inclined bottom 16, such, particles 70, as will amalgamate, as floured mercury, are caught by the mercury on the copper plate 17 the concentrates: 1 finally discharging, from the lowermost end of the box 2 through apertures 18,5which arecoveredby regulatparatus, such as indicatedsat 3, which has M11801 orbital movement; this being known to cause the rapid settling of concentrates and values in pulp. If ipulp be fed through the=pipe 5into the concentrating box 2, the peculiar orbital movement of this box rapidly segre-: 35 gates the concentrates and the values from; the gangue; the latter issuing through the n discharge apertures 12, the concentrates discharging frcmithe apertures or aperture 15 onto the copper plate 17,1 on which particles 90, maybe amalgamated and then the concenw trates are ifinally discharged through the apsertures 18 onto the upwardly \travelin and orbitally gyrated belt or conveyer 4:. n the event that 1 a portion of, the concentrates should ibe discharged onto the apron 13, these will be caughtbythe riflie 14 which is provided with suitable apertures 14 through? which the escaped concentrates will, fall to l the table belt ,4 and be carried upwardly mo 1 thereon n a n The efficiency of the present apparatusis 1 produced because of the peculiar conditions, 1 of separation whereln the ore is primarily concentrated :in the box 2 before it reaches l discharged from the apron13 at a position i on the belt 4: considerably lower than the position at whichlthe concentrates are deposw 'ited 011 61116 belt, so that clear water fed to the belt surface from? a pipe 20 ,will flow over the deposited concentrates vwith less chance of carrylnghthese downward because they are, instead of beingintimately comlabor of the clear water fed to the belt 4 is greatly reduced and consequently a better concentration is produced because of the preliminary concentration or separation of the concentrates from the lighter gangue because of the employment of the bOXQ.

Occasionally, for the purposeof a cleanup, the staggeringplate 6, the concentrating plate 9, and the amalgamating plate 17, may be removed from the box 2, and when I cleaned, readily replaced.

'- in a mass.

The utility of the apron 13 with its rifl'le o'r riflfles '14 is that by it fines may be recovered,

it being well known that it is very difficult to recover fine particles of values in a concen trating apparatus where the pulpis treated heavier values are concentrated and the very light particles may be carried away in the gangue, but an opportunity for the ,collection of the escaping fine values is obtained by the use of the apron 13 'over which the tailings pass. Such fine values as are 001- lect-ed in the riflie 14 are depositedon the belt 4 at a position farther up on the belt than the tailings are, so thatthe collected fines are not subjected to mixture with the tailings and therefore can not be washed away with and by them.
