Apglication filed'August 1, 1924, Serial No. 729,610, and in Germany September 13, 1923.
The present invention concerns a method of wet magnetic separation of ores and other material by means of a drum separator, the material being discharged onto the upper surface of the drum. The invention consists in continuously discharging water or other liquid upon the separating surface so as to form a continuously renewed relatively thick layer 'of liquid on which-the material, dry or wet, is discharged. The magnetic particles penetratethe layer of liquid under the influence of magnetic force and their Another feature of the invention .is-the idea of subjecting the material to a prelimlnary cleansing by means of a liquid jet directed through it. The particles removed by this liquid no longer enter into the separating process and the bulk of the waste material from which the magnetic particles are to be separated is thus advantageously reduced.
In the accompanying drawing Fig. 1 is a sectional .'ew of a separator,
working according to the new process.
' Fig. 2 shows a longitudinal section through a part of the drum of said separator.
Fig. 3 shuts a longitudinal section through parts of-a further modified form of the drum.
Around a magnetic pole a rotates a drum 7) upon which ring-shaped aum'liary poles c are fixed in .the usual 'mannerQ A pipe (Z squirts water or'any other liquid continuously against the walls of the ring-shaped space e formed bythe auxiliary poles (rand drum-mantle bin such a way'that a film of water, which is continuously renewed, 1s
formed on said walls, The material to be separated is introduced to the auxiliary poles bya feeder f at a spot placed behind thej'et d in the direction of the rotation'of the drum. The liquid squirted against the side walls of space crises over the upper auxiliary poles in such a. way that upon their outer cylindrical surfaces a film of liquid is likewise formed. The formof the section of the auxiliary pole rings may be such asdrawn or any other whatsoever. There may be arranged between feeder f-and the attracting auxiliary pole edges a second water jet 9 which squirts transversely through the dropping stream of the crude material effecting thereby'a cleansing of the raw material.
In the apparatus shown in Figure 3 no auxiliary poles are fixed on the drum 7). Here the ring-shaped separating space e is formed by annular rings 71 fixed on the drum 6. The introduction of the liquid forming the film can be effected in the manner shown in the first described embodiment, or in any other suitable way, the manner in which it is introduced being immaterial to the invention.
The process is applicable both for fine and a rotating separator element having an outwardly open circumferential channel, means for delivering a fluid to the side wallsof said channel for formin a film thereon,
feeding means above sai channel for the material to be separated and a liquid jet directed transversely through the material as it falls from said feeding means to the separator element.
'2. In 'aiwet magnetic separator comprising a rotating separator element having an outwardly open circumferential channel, means for delivering a fluid at the base of the Side walls of-said channel'for forming a. filmthereon, and means for feeding the ma-- terial to be separatednnto'said as and for the purposedescribed.

3. In a process of wet se aration by ineans of a magnetic spearator, t e step of directing a liquid jet through the material to be separated-prior-to' the delivery of the ma)- terial to the magnetic separator whereby particles carried along by said jet are rethe magnetic-sepimoved from the action of arator.
