Brief introduction of gold panning equipment

Gold-bearing minerals are divided into placer gold mines and mines. Therefore, there are two main types of gold panning equipment: one is placer gold panning equipment, which mainly adopts the principle of gravity separation and mixed mercury. One is mine crushing gold mining, which mainly adopts gravity separation, flotation, mixed mercury and cyanidation. Placer gold mineral processing equipment is mainly used in places with rivers or areas with sand and other raw materials, especially on the banks of rivers and dry riverbeds. Mine crushing equipment is used in mines with gold deposits, and gold-bearing ores need to be crushed and ball-milled before gold separation.

Technological process of gold panning equipment:

The placer gold elutriation equipment is mainly mixing tank, vibrating screen, jig or centrifuge. Both the stirring chute and centrifuge can realize the mechanized cleaning of coarse concentrate, with large capacity and high recovery rate; From the point of view of process configuration, it also reduces the space position and occupied area compared with the fixed chute, and will undoubtedly replace the single fixed chute process. The equipment configuration of this process is compact, which makes rational use of the space and natural height difference of gold panning equipment and realizes the gravity return of pulp, thus simplifying the gold separation process. In addition, the selection operation reduces the loss of gold. This process will eventually replace the chute-jig process. In addition, the dewatering and desliming process of raw ore will be added to the gold panning equipment; Gold-bearing heavy sand is extracted, and the final product is extracted in onshore concentrator, which can simplify the gold separation process on gold mining equipment, reduce the loss of gold and improve the recovery rate of gold separation. Gold washing equipment: The cylinder screen for ore washing should further strengthen crushing and screening, strengthen mechanical and hydraulic functions, prolong the retention time of materials in the screen and increase the effective screening area (above 25%). The annular retaining ring, spiral crushing teeth and vertical lifting plate in the screen should be further studied in order to enhance the crushing effect and achieve the best gold separation effect when used in conjunction with the centrifuge.
