PROCESS OF SEPARATING MAGNETIC FROM NON-MAGNETIC PARTICLES.

SPECIFICATION forming part of Letters Patent No. 410,876, dated September 10, 1889. Application tiled March 29, 1888. Renewed January 26, 1889. Y Selial No. 297,747. (No model.)

To cir/ZZ whom it may concern,.-

Beit known that I, GURDON CONKLING, a citizen of the United States, residing at Glens Falls, in the county of Warren and State of New York, have invented new and useful Improvements in the Process of Separating Iron or other Magnetic Particles from Non-Magnetic Substances, of Which the following is a specification.

The principal object of my invention is to remove. from magnetic iron ore the particles of iron free from phosphorus or other detrimental impurities in an economical manner; but my invention can be applied with advantage to many othersubstances where it is desirable to separate magnetic particles from non-magnetic substances.

The apparatus which can be used in carrying out my invention is illustrated in the accompanying drawings, in which- Figure 1 represen ts a vertical section in the plane a Fig. 3. Fig. 2 is a Asimilar section in the plane y y, Fig. 3. Fig. 3 is a plan or top view. Fig. 4 is atransverse section in the plane .e z, Fig. 1. Fig. 5 is alongitudinal vertical section of a modification.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates a trough, which is supported by the frame B and which is placed in an inclined position. (Best seen in Fig. 2.) For the purpose of adj Listing the inclination of the trough the following means may be used: To the under surface of saidtrough, near one of its ends, are firmly secured two eyes a., one near each side, and through these eyes extend a rod b,which has its bearings in the frame B. The opposite end of said trough is supported by tWo arms c c, Figs. 1 and 4, which are rnily secured to its under surface and which are provided with slots c. Through these slot-s extend studs c2, the outer ends of which are provided with screw-threads to engage with nuts cs, so that the trough can be turned on the rod b and secured to the required inclination by means of the nuts c3.

Above the trough A is situated an endless belt C, which runs over two drums D D, the shafts of which have their bearings in standards E E, and to one of which is imparted a revolving motion by suitable means, such as a belt and pulley. In proximity to the endless belt C are placed one or more magnets F, which maybe permanent magnets orplates magnetized by electro-magnets. The magnets F are secured to transverses F', which are supported by screw-studs f f, so that the magnets F can be raised or lowered. By -referring to the drawings, (particularly Fig. 1,) it will be seen that the belt C is placed in an inclined position to correspond to the inclination of the trough A. If the inclination of the trough A is changed, that of the belt C must also be changed to correspond, and in order to accomplish this object in the simplest possible manner I place the standards E E, which form the bearings for the shafts of the drums D D, upon a frame Il, which is firmly connected to the trough A, and the screw-studs f f, which support the transverses F and magnetic plates F, are also secured to this same frame, so that if the inclination of the frame A is changed the belt C and the magnets F must follow, and the required relation between the trough and the belt is preserved at all times.

The substances to be separated, after having been comminuted to a suitable iineness,are mixed Withwater or other suitable liquid and conducted in a thin stream upon the trough A. When the apparatus is to be used for separating the iron particles contained in the tailings of a wet-ore separator, such as a jigger, such tailings may be conducted to the trough A directly from the jigger through a trough I. As the stream containing the substances to be separated passes beneath the belt C, the magnetic particles contained therein are lifted up from and out of contact with said stream by the magnets F F, so that they adhere to the under surface of the belt C, and by this belt they are carried away in the direction of the arrow marked on said belt in Fig. 2 until they reach the scraper J, by the action of which they are swept off from the belt and caused to drop down into the receptacle K.

From this description it will be seen that the magnetic particles contained in the stream of liquid running down over the trough Aare lifted'up from and out of said stream by the attraction of the magnet or magnets F and then collected in the receptacle K, while the TOO stream carrying the `non-magnetic particles continues on its course without obstruction, and the particles which have been attracted by the magnets are not liable to be swept ott' by the stream of liquid passing down over the trough.

In the example shown in Fig. 5, the letter A designates the trough, which is supported by the frame B. C is the endless belt7 which ex- Io tends in the directionot the trough and beyond its lower end. The magnetic particles which are attracted by the magnet Fand adhere to the belt C are collected in the receptacle K.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

The Hthin-described process for separating magnetic from non-magnetic particles, which consists in exposing a running stream ot' liquid containing the substances to be separated to the action of a magnet, lifting the magnetic particles carried by said stream up from and out of contact with the stream, and finally conducting the particles which have followed the attraction of the magnet into a suitable receptacle.

In testimony whereof l have hereunto set my hand and seal in the presence ot two subscribing witnesses.

GURDON CONKLING.
