FIELD: gold-producing industry, particularly, concentration of finely dispersed heavy concentrates containing finely dispersed gold and magnetite. SUBSTANCE: device may be used at placers, concentration mills and heavy concentrate concentration plants. The device for withdrawal of magnetite from finely dispersed heavy concentrates by magnet effect has continuous loading and discharging members and includes chamber for separation of magnetite. Chamber is in the form of vertical vessel rectangular in cross-section 200-100 mm, and height of 180 mm, and made of nonmagnetic materials. The device also has chamber for catching of nonmagnetic fraction. Chamber is also rectangular in cross-section 200-400 mm, 70 mm high. The device has splitter for formation of row of flows-streams from loaded heavy concentrate. EFFECT: higher efficiency of magnetite withdrawal. 1 dwg, 1 tbl |
