K. YANO GOLD DUST EXTRACTOR Original Filed July 1, 1921 Patented June 2, 1925.
UNITED STATES KEIZO YANG, OF NISHIKU OSAKA, APAN.
GOLD-DUSTQEXTRACTOR.
Application filed July 1,1921, Serial No. 481,893. Renewed February 23, 1925.
To all whom itmtay concern:
Be it known that I, Knrzo YANO, of No. 7 Sanchome Awaza-Kamidori, Nishiku Osaka, Japan, have invented certain new and useful Improvements in Gold-Dust Extractors,
"outlet for amalgam. The special feature of this invention is that the parts of the water pipe where mercury is introduced are made to form vertical drums, with markedly larger section compared with the other parts, to diminish the velocity of water and to prevent floating motion of mercury par ticles. The drums are also providedwith a vast number of small compartments to confine the amalgam formed, and anumber of grid shelves, installed in the lower and upper parts of the same respectively. The outlet of the last drum ends in two small branch pipes whose exits are made to op pose each other, and retard water velocity to reduce .loss of mercury to any extreme. It is the advantage of this invention that almost all of the defects experienced in other apparatuses of like nature known heretofore are got rid of by this invention nearly to perfection.
Figure 1 shows the side elevation, partly in section, of the general arrangement of this invention, while Figure 2' shows a side view of the manifest manner of pouring mercury, the same parts being denoted by the same symbol throughout all thedrawings.
In this invention a stationary drum ,8 is installed concentric around va revolving filter-drum 2, which latter contains a waterinjection drum 1. At one end of 3 there are fitted two vertical pipes 4 and 4, with a centrifugal pump connected to the lower end of 4. The pump 5 serves to give water a pressure head sufliciently large to aid the water head in the pipe 4 in forcing water and mercury layers to be mentioned hereafter upward in the drums.
The pipe 4 is extended further and bent over and over to form a series of vertical drums, only two of which are shown in the drawing by the symbols 9 and 10. The end of the last drum branches to two pipes 6 8 for mercury and amalgam.
a proper amount.
oppose that from 7. The lowerend of 7 a is'extended downward to form a collector The section of the drums 9 and 10- is made considerably greater than the other parts to retardthe velocity of water. As shown in the drawing, a nozzle-plate 11 is fitted at the lowerend of each drum, with a nest of small nozzles 12. In the middle part of the 'drum, the shelves 18 and 13 are provided with numerous small; compartments 14. and .14 to receive mercury. A
number of grid shelves 15 provided with many apertures 16 arranged in staggered relation are also installed in the upper part of 9 and 10. I I
Each drum" has an inlet 17 for mercury and an outlet for amalgam 1'8atthe bottom of the drum for tapping out the amalgam. External to thedrums, a working handle 19 is provided to work the nozzle-plate 11,
giving the latter small displacement to ensure close mixing of mercury and gold-dust by changing thedirection of water jets.
The object of this invention is to separate and extract pure metal from metal-bearing gravel, for instance gold in alluvium, or the like, in'a more efiicient and economical way than by other apparatus of like nature heretofore known, the working process being explained below.-' a
The gold-bearing gravel is charged into the filter-drum ,2 while mercury is supplied to the drum 9 and 10 fromthe inlet 17 in The gravel set in rotation by thefilter-drum 2 intermingles with water jets from the injection drum 1, and
m ud-water containing gold in more concentrated con'ditio nis led to flow down the water pipe 4, pebbles and coarse sand being rejected out from the filter.
A pressure head is given tothewater coming down the pipe 41 by the pump 5, and consequently the water delivered from the pump forces the mud-water from the pipe 1. to be injected upward through the nozzles 12 in the nozzle-plate 11. The energy given to the water jets is of such strength that the mercury introduced into the drum 9 is blown upward by the jets and confined into the compartments 14 and 14 on the shelves 18 and 13. Moreover there is a sufficient energy left in the water to repeat similar action on the mercury in-the succeeding drums 10 and so forth, after passing through several layers of mercury and the apertures; 16 in %;-thegrids 151 of the druni'Q.
The Water leaving the last drum is di- 5 vided into two flows through thepipesl 6. and,
j "of the drum, the. friction between i the particles of mercury. and thelwalls of Hand 14 and the eight of mje'rcury, itself icombinegto prevent the tendencyiof mercury to {flow 1:, outside; the ;compartments, despite the said upwardflow ,of waterjinthedrum. Of, a ,QsmallQpercentage ,ofithe metal which reach the grids .15',"; .-greater .p'ortion is .refiected downward by lc'ollision; with," the grids and h .confined again. into the cnm 'a'rgtments, v 14 and 14'. Metallic parti esc n the drum 9 are similarly treated ,in'the s 'ic ingjdrums, resulting in a very higli', perfce'ntage ot gold extraction. l
