SU142224A1 - Apparatus for washing gold-bearing sands and extracting gold - Google Patents

Description

Devices are known for washing gold-bearing sands and extracting gold. But they have a low degree of gold recovery due to the ash of the fines with sludge from the depositors. A particularly large carryover of gold with sludges is observed when washing clay gold-bearing sands.

The proposed device improves the productivity of gold mining from clay gold-bearing sands.

For better extraction of gold from washing sludge, the device is equipped with gateways. In addition, the device has a swinging screen for separating sand washed in a trough into a gold-containing product and waste rock, n waste. The gold product is then sent for further enrichment.

The drawing shows the proposed device in the context of the n section along aa.

The device works as follows. Gold-bearing clay sands after appropriate preliminary preparations; post trough in a trough. This also serves water. By rotating the shaft 2 of a rectangular section carrying the blades 3, after otmuchivaniya clay component moves to the discharge chute 4 and fall on the roar 5. Here the sands are divided into two products; the lower one, the gold content, falls through the throat of a jigger into a jigging jar, and the upper one (czsta rock) goes into the heap. The resulting ia bottom of the Mofiki during the erosion of the sands, the gold-enriched bed is removed through hatches (not shown) located along the length of the trough.

No. 142224-2 -

To perform this operation, one of the longitudinal walls of the trough is cut horizontally and bent outward at an angle of 45. The fine fraction of gold from washing sludge is caught by fleecy locks b, which are attached to the bent / wall of the trough at a level slightly below the level of sludge in the trough.

Claims (2)

1. A device for washing sand and extracting gold, which is a sink with a single shaft, carrying a blade, characterized in that, in order to extract gold from washing, its trough is fitted with sluices and swinging screen, to separate the sand in the trough gold-containing product, directed for further enrichment, and waste rock, I’m going to garbage. 2. The device according to claim 1, characterized in that, in order to remove the gold-rich bed from the trough, one wall (longitudinal) of the trough is bent at an angle of 45 and cut along the edge forming the horizontal straight line.
