Ihe surface vof the table is covered with linoleum orj other similar material shown at 7"i 1rFigures 3 and"4,antl 't'his covering" arefthe longitudinally extending 15a'rallel rifl'les '8. 'Efiten di'ng diagonally across the riflled surface adjacent "the" concentrates djs'cliarge end of the deck, i'sjthe channel 9 const ituti ng the present "improvement; which in the preferred 'construction illustrated in thefdrawing,is formed by grooving thewooden body portionot the table" and depress'ingt-he lino- "leum intothe groove? 4 i 'T11e"oncenfiiaun surface of the table is first brought to a perfect plane by carefully dressing the jlooards of whi'cli'it is built," the groove; or channel being thencut "to the demove alongth'fspaces v f e e 'I PQ p or other line as may be most suitable for length, but may be made deeper or wider at one end that at the other. It may, for in stance, be deep and 4." wide at the upper end which receives the larger portion of the concentrates, and or less in depth by 2 in width at its lower or discharge end.
.gangue 1n the Such changes in dimensions are governed by the amount of mineral to be removed as concentrate, the coarseness to which the ore is ground, and the tonnage which the table is to treat.
The groove or channel having been cut in the concentrating surface, the linoleum or other covering is laid in place and pressed down into the groove to accurately follow its contour. In case the deck is to be covered with concrete in place of linoleum, a form may be used to accurately mould the groove although this is not necessary.
The rifles may be terminated at opposite sides of the channel by interrupting their continuity as shown in Figure 3, or they may be made continuous as in the ordinary construction and formed to extend across the groove in constant contact with its bottom surface as illustrated in Figure a.
While the first mentioned form is preferred since it provides an unobstructed channel for the removal of the extraneous matter separated from the concentrates, the other form is advantageous under conditions tending to oppose a continuation of the movement of the values through the spaces between the rifles.
In the form shown in Figure 3, the portions of the rifles at the side of the diagonal channel adjacent the discharge-end of the table, are slopingly extended'into the channel for the purpose of facilitating the transverse movement of the concentrates.
In the operation of my improved concentrator, the material delivered at the upper edge of the deck flows across its laterally sloping rifled surface, the lighter gangue passing over the rifles and discharging at the lower edge of the deck, while the mineral values are retained in the spaces between the rifles and moved to the mineral discharge end of the deck by its vibratory differential motion.
The concentrates segregated from the spaces between the rifles frequently carry particles of rock, sand or other foreign matter which owing to their size their formation or their constitution, fail to follow the flow of the tailings across the rifles, and when the segregated mineral enters the diagonal channel, these accompanying lighter foreign particles are caught in the current of liquid flowing through the same and continue in the channel to the lower edge of the table, while the minerals are gradually carried out of the channel onto the surface of the table and continue their movement between the rifles to the concen trates discharge end of the same.
Having thus described my improved concentrator. I desire it understood that other methods of forming the diagonal channel in the rifled surface thereof, besides those shown in the drawings and hereinabove explained, may be availed of within the spirit of my invention as defined in the hereunto appended claims.
It is not positively essential that the chain nel should discharge in the tailing discharge edge of the table since it is possible to terminate it in the surface of the deck adjacent said edge or in or near the mineral discharge end of the same, in which case the matter flowing downwardly through the channel would still be discharged from the deck separate from the concentrates.
What I claim and desire to secure by Let ters Patent is:
1. A concentrator comprising a table having a transversely inclined, rifled concentrating surface, and means for causing a movement of concentrates between the riffles to a discharge-end of the same, the table having a channel extending transversely of its rifled surface.
2. A concentrator comprising a table having a transversely inclined, rifled concentrating surface, and means for causing a movement of concentrates between the riffles to a discharge end of the same, the table having a channel extending diagonally of its rifled surface.
3. A concentrator comprising a table having a transversely inclined rifled concentrating surface, and means for causing a movement of concentrates between the rifles thereon to a discharge end of the same, the table being provided with a groove extending diagonally of its rifled surface.
4. A concentrator comprising a table having a transversely inclined rifled concentrating surface, and means for causing a movement of concentrates between the rifles thereon to a discharge end of the same, the table being provided adjacent its concentrate discharge end with a channel extending diagonally of its rifled surface.
5. A concentrator comprising a table having a transversely inclined rifled concentrating surface, and means for causing a movement of concentrates between the rifles to a discharge end of the same, the table being provided with a channel extending diagonally of its rifled surface, and the continuity of the rifles being interrupted in said channel.
6. A concentrator comprising a table having a transversely inclined rifled concentrating surface, and means for causing a movement of concentrates between the rifles of the table to a discharge end of the same, the table being provided with a groove extending diagonally of its rifled surface and the bottom of the groove sloping upwardly to the concentrating surface in the direction of the discharge end of the table.
7. As a new article of manufacture, a concentrating table having a longitudinally rifled transversely inclined surface and provided with a channel extending transversely of said surface.
8. As a new article of manufacture, a concentrating table having a longitudinally rifled transversely inclined surface and provided with a channel extending diagonally of said surface.
9. A concentrating table having a transversely inclined, longitudinally rifled and diagonally channeled surface, and means for causing a movement of concentrates between the rifles to a discharge-end of the same.
In testimony whereof I have aflxed my signature.
