Abstract

The invention discloses a belt-type multi-stage multi-gradient magnetic separator which comprises a magnetic separating device, a multi-stage material conveying device and a tailing conveying device, wherein the magnetic separating device comprises a belt-type conveyer and a magnetic system arranged inside the belt-type conveyer; the multi-stage material conveying device comprises a plurality of belt-type conveyers which are arranged on one same horizontal height and are arranged at intervals; the tailing conveying device is used for receiving and conveying tailings from the multi-stage material conveying device; the magnetic system comprises a plurality of magnetic field areas of which the magnetic field strength is gradually weakened along the material conveying direction; non-magnetic areas are arranged between every two adjacent magnetic field areas; the magnetic field areas cover the gaps between adjacent belt-type conveyers of the multi-stage material conveying device. The invention further discloses a method for mineral separation by using the belt-type multi-stage multi-gradient magnetic separator.

Description

technical field [0001] The invention relates to a belt-type multi-stage multi-gradient dry separator and a method for ore dressing using the belt-type multi-stage multi-gradient dry separator. Background technique [0002] Traditionally, wet magnetic separation is generally used for beneficiation of magnetite. However, wet magnetic separation requires a lot of water, which is very costly in arid and water-scarce areas, and even makes it impossible to carry out mineral processing. Therefore need to develop a kind of dry separator that does not need water or needs very little water to carry out beneficiation. [0003] Aiming at the problems existing in the prior art, the present invention proposes a belt-type multi-stage multi-gradient dry separator and a method for beneficiation using the belt-type multi-stage multi-gradient dry separator, which can replace wet magnetic Selection method for mineral processing. Contents of the invention [0004] According to the present i...
