METHOD wet magnetic separation of magnetite ores AND DEVICE FOR ITS IMPLEMENTATION

摘要

1. A method of magnetic separation of magnetite ore, comprising feeding pulp into the working zone - the space between the bottom of the tub and the rotary drum with nonmagnetic placed inside the magnet system of permanent magnets, characterized in that the separation is carried out in two stages at two separators arranged in series, wherein a first separator receiving the released first receiving the concentrate and tailings separation fed into the first intake of the second reception separator, where the second concentrate is allocated receiving and dumping hvosty.2. The separator for the wet magnetic separation, comprising two rotatably mounted nonmagnetic drums arranged therein magnetic systems, baths, and boxes for nonmagnetic and magnetic product, characterized in that the separator of the first reception of the installed sequentially drum magnetic separator equipped with a chute discharge first concentrate receiving and has an apparatus for discharging tailings, and the bath of first and second separators connected receptions intermediate tray for feeding separation of tailings in the first reception of the second separator priema.3. Separator according to claim 2, characterized in that the first separator receiving gap between the magnetic drum and the bottom of the bath is increased within the range of a half to three times, than the second separator priema.4. Separator according to claim 2, characterized in that the first bath separator receiving proofed pulpy.5 level regulation. Separator according to claim 2, characterized in that a part of the working area of ​​the magnetic drum separator has a first reception inhomogeneous magnetic field gradient.
