supplying steam, hot Water, or the like `to the coils`13`; or heat may be otherwise applied. rIhe pumping or elevating mechanism isthen actuated to convey the liquidand pulp from the bottom of the tank and to distribute them in a comparatively thin layer over the aerating apron 35', the said aerating apron `providing a convenient means for the intro- 'duction of oxygen into the liquid, for example, into cyanid or into ferrous sulfate solutlons.' The liquid and pulp flpw from the aerating apron back into the tank and are again brought up by means of the pump.

' After the charge has been agitated for a suitl able time the pumping is `stopped and the solutions allowedto filter through the 4cells .24 and to pass out through the outlet openings 27 and the valves 28. At the same time Wash solutions, or water, are run in through the pipes 33 and under the canvas 21. v The canvas `serves'the purpose of thoroughly and evenly distributing the-inflowing "Wash, so that there is practically no channeling of the pulp, but an even and' thorough' displacement of the liquid therefrom.

s y terthe filtration has been operated for a suitable timejl close the valves 28 and introduce Wash solution, or Water, through the opening 39 and through the pipes 26, 31 and 525 thereby dislodging the slimes or solid lmaterial which has collected on the filter I. then run in more washy solution either at the Abottom of the tank,for through the cells, or introduce it at the to the best resu ts, depending on the character -of'the ore. After the charge has been agitated, heated, aerated and filtered tothe vdesired degree, I open the valve 14 and run the contents either to waste or subject them to such further treatment as lmay be desired.

In this apparatus I prefer to use the filter cells described and claimed in my copending application, Serial No. 329,611, tiled August Qt 1906. ther formsof filter cells may l however be used to advantage and I do not limit myself to this term. While I have shown a square tank, Imay use a round tank such as that shown in' my l?atents, Nos. 785,214, 834.803 and 866,858.

The apparatusl will be employed for the tal'or complete recovery of the liquids f the tank, and again startl the pump an agitate` .the mixture for a suitable time, when the and of the ore values, depending upon the character of the ore. For certain ores and for certain methods of treatment the cocoa matting and canvas covering on the bottom of the tank may be omitted.

I claim:

1. Apparatus for treating ore-pulp, coniprising a tank, means for circulating and aerating material therein heating means for the circulating material, a plurality of filter cells in position to be submerged in the material in said tank,and means for withdrawing liquid from thetank through said cells.

2. Apparatus for. treating ore-pulp comprising a tank, means for circulating and aerating material therein, a plurality ot filter cells in position to be submerged in the matcrial in said tank, means for withdrawing liquid from the tan-k through said cells, and means for distributing wash liquid in the lower portion of said tank.

3. Apparatus for treating ore-pulp, comprising a tank, means for circulating material therein, heating means for the circulating material, a plurality off-liter cells in position to be submerged in the material in said tank, and means for withdrawing liquid from the tank through said cells. p

4. Apparatus for treating ore-pulp, comprising a tank, filter cells vertically disposedv therein heating means'pfor the contents of said tank, and external connections to the upper and lower portions of said filter cells.

5. Apparatus fortreating ore-pulp, comprising a tank having a converging bottom and having circulating means, filter cells in position to be submerged in the material in saidV tank and a filter disposed above and substantially parallel to the bottom of said tank. t

6. Apparatus for`- treating ore-pulp, com prising a rectangular tank prov1ded with circulating means, a`v plurality of 'filter cells in said tank in position to be submerged in the material therein,` and heating pipes in said tank.

7. Apparatus for treating ore-pulp, comprising a rectangular tank having a converging bottom and provided with circulating means, heating means for the circulating material, a plurality of filter cells in said tank in position to be submerged in the material therein, means `tor withdrawing liquid from the tank through said cells, and a discharge gate at the bottoma of said tank.

In testimony whereof I affix my signature in presence oltwo witnesses.
