AUGUST SEINSCHE, OF MILW'AUKIE, OREGON.
GOLD-SEPARAT OR.
Application filed May 5, 1919.
It (In 11171.01)? it may concern:
Be it known that I, AUGUs'r SErNsoHn, a citizen of the United States, residing at Milwaukie, in the county of Clackamas and State of Oregon, have invented new and useful Improvements in Gold-Separators, of which the following is a specification.
This invention relates to apparatus used in mining, particularly in gold mining, and has for its object the provision of apparatus whereby extremely fine particles of gold may be seiarated froin the crushed quartz or from placer sand while avoiding the use of electrolytir or cyaniding methods.
An important object is the provision of an apparatus of this character which is complete in. itself and which is capable of handling a large amount of ore or sand and which will dispense with the use of a stamp mill, conci-intrator and the various other machinery employed in the ordinary methods.
another object is the provision of an apparatus of this character which will be simple and inexpensive in manufacture and installation, which may be readily operated, which will be economical in its treatment of crushed ore, ei'licieut in service, and a general improvement in the art.
With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanyin drawings, in which Figure 1 is a longitudinal sectional view through my device,
Fig. 2 is an end elevation,
Fig. 3 is a plan view, and
Fig. 4 is a detail cross sectional view on the line 44 of Fig. 1.
Referring more particularly to the drawings, the numeral 10 designates a supporting frame formed of suitable planks, beams, or the like, and having mounted upon its top, rollers 11 upon and between which is journaled a rotary drum 12 which has one end 13 open and into the other end of which extends a feed chute 14. Secured upon the frame 10 in position to receive material from the open end of the drum 12, is a hopper 15 provided in its lower end with a discharge opening 16.
Carried by the frame 10 at some convenient location below the drum 12 is a tank 17 adapted to contain oil and provided with a discharge cook 18. Also disposed beneath Specification of Letters Patent.
Patented Mar. 30, 1. 120.
Serial No. 234,711.
the supporting frame 10 is tank 19 provided with draw-off cocks 20 20 and beneath which is disposed some suitable heat producing means 21 which may be any preferred form of stove or burner.
Disposed beyond the end of the frame 10 is a tank 22 adapted to contain a dilute solution of sulfuric acid and which is provided at its lower portion. with a draw-01f cook 23 and at its upper portion with a valved outlet pipe 24 discharging into the top of the tank 19.
Disposed vertically within the tank 22 is a shaft 25 upon the lower end of which is secured an agitator 26 and upon the upper end of which is secured a beveled gear 27 meshing with the bevel gear 28 carried by a transverse shaft 29. A. sprocket 30 is also secured upon the shaft 29 and has trained thereover a chain 31 which is also trained about. a sprocket 32- secured upon one end of a shaft 33 which is journaled transversely upon the frame 10 and which is provided with a large pulley 34 whereby power may be applied to the shaft.
In order to drive the drum 12, I provide upon the shaft 33 a bevel which meshes with a bevel gear 36 on a horizontal shaft 37 which carries upon its other end a sprocket 38 about which is trained a chain 39 which is also trained about a sprocket member 40 of the drum 12.
Also secured upon the shaft 33 at its center, is a roller 41 about which is trained an endless apron 42 which extends in an upwardly inclined direction throughout a portion of its length and which is disposed beneath the discharge opening 16 in the hopper 1 5. Both stretches of the apron 42 are trained over guide rollers 43 suitably mounted upon the frame 10 and the apron is also trained around a pulley 44 mounted in the tank 22. Brushes 45 are properly mounted within the tank 22 and engage the lower stretch of the apron, for a purpose to be hereinafter described. A pivoted lever 46 is provided and carries at its free end a roller 47 carried upon the upper stretch of the apron 42 and acting as a belt tightener' and also as means for mixing the ore and oil.
In the operation of the apparatus, the ore must first be crushed in a dry state sufliciently fine to pass through a screen of one hundred and twenty (120) mesh. If placer sand is used instead of crushed ore, the sand must first be screened to remove the gravel therefrom. This dry crushed material is then poured into the chute 1 1 and into the drum 12 where it will be agitated and dried and from which it will pass into the hopper 15 whence it will drop slowly through the discharge opening 16 and onto the apron 42. The tank 17, as previously stated, contains oil and the cook 18 is so adjusted that the oil will be permitted to drop slowly onto the traveling apron d2 in advance of the falling stream of crushed material leaving the hopper 15. The crushed material will then be impregnated with the oil. As the moving parts of the apparatus are operated the apron 42 will in its travel dump the material carried thereon into the tank 22 which contains dilute sulfuric acid, the purpose of which is to clean the gold and eat off small particles of foreign matter adhering thereto. The function of the brushes 4:2 is to insure all the material leaving the apron and remaining in the tank 22. When the crushed material is thus deposited within the tank 22, the particles of gold, which are coated with the oil, will naturally rise to the top of the liquid within the tank while the useless material will sink to the bottom. The useless material or tailings is withdrawn through the drain cook 16 and the floating particles of oil coated gold will pass through the drain pipe 24 and into the tank 19. As the tank 19 is heated, it will be seen that the oil will be separated from the particles of gold and may be drained or? through the cook 20. If desired, this oil may be returned to the tank 17 and consequently be used over and over indefinitely.
From the foregoing description and a study of the drawings it will be apparent that I have thus provided a simple and inexpensive apparatus for saving very fine particles of gold which have heretofore been unreclainiahle by any other means than the cyanid process which is costly and which is consequently undesirable.
Vi hile I have shown. and described the preferred embodiment of my invention, it of course to he understood that I reserve the right to make such changes in the form, construction, and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claim.
Having thus described my invention, I claim V A. gold separating apparatus comprising a means for feeding ore, an endless traveling apron disposed below and adapted to receive ore from said feeding means, means for feeding oil onto said apron prior to the falling of ore thereonto, a presser roller engaging said apron subsequent to the falling of ore thereonto for pressing the ore and oil onto the apron, a water tank having said apron extendingthereinto at the discharge end thereof, brush members engaging the apron for removing therefrom and causing to fall into the tank any ore adhering to the apron, a draw-off pipe located at the upper portion of the tank, agitating means within the tank, and means for simultaneously driving said apron, and said agitating means.
