An electromagnetic pulsed-wave system having an electromagnetic boom for generating a time-varying pulsed-wave to control a colloidal mixture disposed in water and a depository. The electromagnetic boom comprising a plurality of electrically coupled solenoids disposed at the water for providing electromagnetic pulses to generate the time-varying pulsed-wave to transport the colloidal mixture. The depository having an electromagnetic ramp magnetically coupled with the electromagnetic boom and a separation receptacle for separating magnetized particles from the colloidal mixture.

The invention relates to a method for separating feed material, wherein the feed material comprises at least one ferromagnetic material fraction and a non-ferrous material fraction, wherein a conveying stream is fed to a first separation of a first ferromagnetic material fraction, in particular by means of a first magnetic separating device (1), wherein the conveying stream is subsequently fed to a second separation of a second ferromagnetic material fraction from the conveying stream, in particular by means of a second magnetic separating device (2), and wherein a redistribution and/or reallocation of the material of the conveying stream takes place between the first separation and the second separation.

A system and method directed to the economical recovery of valuable iron constituents from iron blast furnace and steel-making slag fines wherein the slag is obtained and subjected to a series of classification steps which progressively sort the slag fines by various physical characteristics, including magnetism, size, and density, into relatively iron-rich and relatively iron-poor classifications, resulting in the isolation of iron-rich commercial byproduct at one or more of the classification steps.

A method and apparatus for continuous magnetic filtration of ferrous mill scale from liquid solution employs a tank for receipt of fluids laden with mill scale. A curvate trough within the tank receives a rotatable magnetic drum and establishes a channel therebetween. An air compressor and associated manifold generate bubbles within the tank and adjacent the rotatable magnetic drum. The mill scale attaches to the bubbles, which are attracted to the surface of the drum where the mill scale accumulates. The accumulation of mill scale particles is moved about the surface of the rotating drum by a scraper proximate the surface thereof. By moving the accumulated mill scale particles to regions of the rotating drum that are of a magnetic force insufficient to retain them upon the surface of the drum, the mill scale particles are removed and passed to a conveyor system.

The invention relates to a method for the chip-removing production or machining of a workpiece by means of a tool, in which method a liquid, which mixes and accumulates with the chips produced during the machining process, is used for lubricating and/or cooling the machining process, and the chips are discharged from the accumulation counter to the downhill force along a discharge path by means of a magnetic force, wherein a return flow of the liquid carried by the discharged chips occurs due to the downhill force, and the return flow is deflected out of the discharge path and/or the discharge path has at least one point at which the supporting surface is temporarily withdrawn from the discharged chips.

The present invention includes a method of controlling an oil spill through introduction of a plurality of magnetizable particles into the oil spill in an amount sufficient to form a colloidal mixture. An absorbent is also introduced into the oil spill to form an absorbent mixture. A magnetic field can be applied to the system to move, manipulate, or otherwise control the absorbent mixture in response to movement of the magnetic field.
