摘要： The invention relates to a magnetic separator for the dry separation of material particles having different magnetic susceptibilities, wherein a rotatable cylinder that comprises a stationary magnetic device arranged therein, and extending essentially across its length, is disposed. A sorting chamber is furthermore provided for which extends along at least a portion of the outer surface of the cylinder in the circumferential direction of the cylinder and parallel to the longitudinal axis of the cylinder. The magnetic separator according to the invention features means for the dispersed output of material particles into the sorting chamber, as well as means for generating a stream of conveying air in the sorting chamber. A motor for rotating the cylinder around its longitudinal axis, wherein, during operation, the outer surface of the cylinder is moved by the rotation of the cylinder in a direction essentially perpendicular to the direction of the stream of conveying air is, moreover, provided for.

摘要： A magnet assembly having selectively removable magnet members can be attached to, or placed in the vicinity of, a conventional bell nipple or riser on a drilling rig to generate a magnetic field within a wellbore. The magnetic field catches falling metal objects and prevents such objects from passing beyond the magnet assembly and entering subterranean portions of a wellbore. Hatch doors are provided for easy access to inner portions of the magnet assembly.

摘要： The present disclosure provides an apparatus for sorting a particulate material. The apparatus comprises a receiving portion for receiving the particulate material having a particle size within a predetermined range of sizes. The apparatus also comprises a distributor for receiving the particulate material at an upper end thereof and having a sloped distribution surface along which, in use, the particulate material passes substantially by gravity. A surface area of the sloped distribution surface increases towards a lower end of the distributor to facilitate a monolayer feed stream of the particles exiting and falling from a lower end of the distributor distributed as a curtain-like stream of particles. The apparatus further comprises a magnetic element for generating a magnetic force that is directed such that the particles of the falling feed stream that exit the lower end of the distributor have pathways that depend on magnetic properties of the particles. The apparatus also comprises sorting portions for sorting the particles based on the pathways of the particles.

摘要： A system and method for separating an electrically conductive particulate material, such as gold, from other materials. A ferromagnetic core is formed in a torroidal-like shape and is provide with a gap. A coil is wound around the core and an alternating current is applied to the coil to induce an alternating magnetic field at the gap. A stream of particles is directed into the gap. The frequency of the alternating current is set according to the specific resistivity of the particulate material which is to be separated from the rest of the material and according to the size of the particles which are to be separated from the rest of the material. By properly adjusting or setting the frequency of the alternating magnetic field, the first particles are imparted a trajectory which is different than the trajectory of the second particles in the particle stream. In order to account for the size of the particle, the present invention increases the frequency of the alternating magnetic field as the size of the first particles decreases. The present invention has particular application for separating particles of gold from other materials.
