CONCENTRATING-TABLE.

Specification 0! Letters Patent. Patent d N 30 1920 Application filed February 19, 1920. Serial No. 359,993.

T 0 all whom it may concern:

Be it known that I, IRVING KLINDT, a citizen of the United States, residing at Round Mountain, in the county of Nye and State of Nevada, have invented a new and useful Concentrating-Table, of which the followin is a specification.

My invention relates to concentrating machines and is more particularly directed to the type of machines known as wet concentrators and which are especially adaptable for the treatment of ore pulps and slimes.

The object of the invention is to provide a horizontal concentrating table of shallow box form and to longitudinally reciprocate the table to cause'a stratification of the pulp and the discharge of the tailings in a plane transverse to the direction of reciprocation.

Another'object is to provide a concentrating table combined with means for feeding the ore pulp along the longitudinal center of the table and directing it transversely to r the direction of reciprocation of the table, the longitudinal reciprocation of the table causing the heavier mineral values to form a lower strata on the table surface where they discharge into a longitudinal concentrate trough in the center of the table surface, and causing-the lighter tailings to be discharged over the side boards of the table in a direction transverse to the direction of reciprocation of. the table. 7

A further object is to provide a concentrating table reciprocated in a substantially horizontal plane and in which the pulp bed is continuously maintained in a level plane, said table having a concentrate slot or trough extending in a plane parallel to the direction of reciprocation.

Another object is to provide a c0ncentrating table in which the pulp bed is maintained in a level plane and the pulp is fed along the longitudinal center of the table and parallel to its direction of reciprocation, and is directed transversely beneath the surface of the pulp bed. 7

Various other objects and advantages will be more fully apparent from the following description of the accompanying drawings, which form a part of this disclosure, and which illustrate apreferred form of embodiment of the invention.

Of the drawings:

Figure 1 is a side elevation of my improved concentrator.

Fig. 2 is a top plan view.

Fig. 3 is a top plan view with the feed trough removed.

F 4 is a longitudinalvertical section.

F g. 5 is an end elevation.

1g. 6 -is an enlarged transverse section illustrating the separation of the ore pulp.

In the drawings, A designates the concentrator table which is supported upon vertical legs 13, the legs being attached to the under surface of the table and to the base 1 of the machine, by angled brackets 2. The legs are formed of flexible metal or wood to permit a relatively slight longitudinal reciprocation of the table and at the same time are transversely rigid to prevent any side motion thereof.

The table. A is given a reciprocating movement, longitudinally, by any suitable operating' mechanism, such as, by means of an eccentric link device, as indicated at 3.

The table is of shallow box form having a table surface a which is substantially level, longitudinally, and which is slightly inclined downwardly and inwardly to a medial concentrate slot 5 which extends parallel to the direction of table reciprocation. Discharge spigot-s 6, by which the discharge of the concentrate from the slot is regulated, communicate with the concentrate slot and are adapted to discharge the concentrate into a stationary concentrate launder C which is supported beneath and in longitudinal alinement with the spigots, and is slightly inclined to direct the flow oi the concentrate toward one end of the machine. 7

The side boards 7-8 of the table A extend upwardlya distance commensurate to the depth to which it is desired to maintain the pulp bed. The end boards 9, 10 extend upwardly to a greater height than the side boards and the adjacent portions of the side boards are inclined upwardly to the height of the end boards, as indicated at 11, 11. This provides a table having higher marginalwalls at its opposed ends, and the purpose of this structure is to prevent the ore pulp being thrown or washed over the table ends by the sudden changes in table movements. Each of the side boards 7, S extend below the bottom of the table and into stationary tailings launders D.D which are slightly inclined in a direction in which it is desired that the tailings shall be discharged.

.The feed trough E is longitudinally extended the length of the concentrator table,

the table.

above the concentrate slot 5, and rests upon and is attached to the end boards 9l0 or the trough, as by means of bolts 13, and suiti 'ably spaced front the trough are opposed baflie plates l4l4-which extend longitudlnally the full length of the table and vertically above the discharge orifices 12-l2 and downwardly below the horizontal level of the pulp bed'on the table and below the tops ofthe table side boards 7-8.

It-will be evident from the above, that the feed trough E and the table A, and con- 'nected-parts, will be reciprocated as a unit in a longitudinal direction and in a sub stantia-lly level plane.

In operation, the ore pulp or slime will flow through the'discharge orifices 12-42 and against-the baffle plates 14t1l which will direct the pulp downwardly beneath the surface-of the pulp bed on the table, as indicated bythe arrows 15- -15 in Fig. 6. This flow of the pulp is assisted by the reciprocation of the table which also serves to maintain the pulpin the teed trough in an agi tated state to. prevent a separation in said trough and to'prevent a clogging of. the discharge orifices 12 12.

The reciprocation of the table causes a stratification of thepulp bed, the heavier mineral'values sinking tothe table surface,

I as indicated by the arrows '16-l6 and gradually working into the concentrate slot '5',- and the lighter gangue flowing transversely across the table and overflowing over the table side boards 7-8 and into the tailings launders D-D as indicated by the arrows 17-17 in Fig. 6.

I The spigots 6 may be regulated to continuously discharge the concentrate into the V pulp-anda continuousseparation by which the mineral values seek the longitudinal eenter of'the table and the gangueis directed transversely relative to the direction of recip-rocation and overflows the 'side boards ofthetable.

I claim:
