Abstract

A device for extracting gray concentrates from the tailings of washing sand of placer deposits consists of a trench of a sluice for catching gold, characterized in that it has two troughs, the discharge end of the first of them is at a height of 2.5-3 m, another trough is placed under the drain of the first trough, the width of which is 1.5 times greater, and the slope is 8-10, the gutter has a double bottom, the upper bottom has windows with the entire width of the bottom 0.3-0.8 long, the windows in the upper bottom of the airlock are covered with a 6 mm grid, stacked on top of the bottom lattice stencils, the bottom is solid.

Utility model related to enrichment of useful j cKoria

gravitational methods.

It is known that hydromechanical units (HMU) (I) are widespread for the conversion of alluvial deposits of gold and other valuable minerals. The main component of the GMS is the gateway, which consists of an inclined gutter on which rubber mats, metal mesh, and stencils are laid, designed to impart turbulence to the flow and conditions for trapping heavy minerals.

The disadvantages of this gateway are:

1.When a large amount of schlich minerals is present in the placer, a significant proportion of the concentrate is carried into the dump, because the mineral of the concentrate contains gold in intergrowths or in defects of the crystal lattice. Along with this, the slit quite often contains various valuable minerals that can be extracted and used in combination with gold. (For example, scheelite, cassiterite, cinnabar, garnets, zircons, ilmenite, etc.).

2. The design of these locks allows you to make strips no more than 1-2 times a day, of course, that with a large output of schlich minerals they will be largely lost.

The purpose of this utility model is to further extract the concentrate from the C-JOKOB gateway.

This goal is solved by the fact that the lock channel is raised to a height; at which its unloading end is high enough (2.5-3), another gutter is substituted under the gutter drain, the width of which is 1.5 times greater than the main gateway gutter, and should be 8-10 °, the gutter has a double bottom. The upper bottom has windows in the entire width of the bottom 0.3-0.8 m long. The windows in the bottom of the airlock are covered with a 6 mm grid. Stencil grids are stacked on top of that bottom. The bottom, continuous over it, falling gray concentrates by gravity flow into a separate pump and are transported by a sand pump for collection, with dewatering and loading into a container.

Ne fig. I is a general view of the device.

The device for extracting gray concentrates from the tailings of washing sand of the deposits of large deposits consists of a gutter (I) whose width is 1.5 times greater than the main gutter of the lock, and the slope should be 8-10 °, the gutter has a double bottom (2,3). The upper bottom (2) has windows (4) in the entire width of the bottom 0.3-0.8 m long. Windows c.

gateways are blocked by a grid (6) b mm. Stencil gratings are stacked on top of this bottom. The bottom bottom is solid (3) iio the failed gray concentrates by gravity flow into separate sumps (7) and are transported by a sand pump for collection, dehydration and loading into a container.

EXAMPLE OF SPECIFIC IMPLEMENTATION

The flow of the pulp after passing through the gate collecting gold is directed into the receiving hopper of the gutter, catching a gray concentrate. This gutter has a double bottom. The upper bottom has windows covered by a grid. On top of this beggar laid trellis grids. The pulp is stratified by specific gravity, moreover, the heavy fraction (gray concentrate) through the holes will fall on the bottom with windows, and through the windows on the lower bottom, which has a slightly larger slope to create gravity flow, the flow of gray concentrates. The lower bottom has a discharge end directed to the sump, from which concentrates are pumped into special containers by the Sand Pump. The rest of the pulp stream along the upper bottom over the grate rushes to the discharge.
