FIELD: process engineering. ^ SUBSTANCE: invention relates to ore dressing and may be used in flushing gold- and platinum-containing sands. Flushing plant comprises carcass, main gate with adjoining flat screen, bin with telescopic branch pipe, free rotating cone with spiral ribs, concentrate collection bin, low-filling gates arranged on plant carcass and articulated therewith, and annular trough with tail chute. It is furnished with fixed annular distributing bin with outlet for every low-filling gate, opening shutters arranged under cone drain line. Every said low-filling gate is made up of package consisting of low-filling gate proper and thin-sheet case arranged above low-filling gate to cover its entire catching surface. Aforesaid package may be turned by axles. One of the latter is located at narrow section end while another one is arranged on low-filling gate wide section end. With package turning, the axle in narrow section end is lowered and articulated with plant carcass lock. Second axle of low-filling gate is lifted to height required for concentrate rinsing by water jets fed by irrigation tube. Low-filling gate is arranged with its bottom turned upward. Jacket represents gravity chute to allow directing flushed concentrate into concentrate collection bin arranged under fixed annular distributing bin. Bottom of every said gate is furnished with catching coating made up of rubber mats overlapped by solid-stretched reticulations. Jacket is secured to low-filling gate by fast-release joints. ^ EFFECT: higher yield, efficiency and safety. ^ 2 cl, 4 dwg |
