A gold mining equipment for solid-liquid separation of gold leaching liquid. 【Processing capacity】: 10-250t/d 【Scope of application】: The washing and thickening machine is a special equipment for the solid-liquid separation and washing operation of the pulp after cyanidation leaching, and can be used for the dehydration of uranium mines in hydrometallurgy, light industry and chemical industry.
Xinhai washing and thickening machine adopts the method of continuous ore discharge, which can reduce the multiple circulation of liquid gold, early recovery, and at the same time prolong the time of pulp in the thickening machine and improve the leaching rate;
The washing and concentrating machine realizes countercurrent washing, continuous operation, large volume and high washing efficiency;
Small footprint, energy saving, and simplified process configuration;
Reasonable structure, low operation and maintenance cost.
Xinhai washing thickeners include a two-layers washing thickener and a three-layers washing thickener. Taking the three-layers washing thickener as an example, the pulp is fed by a feeding tube, and the pulp that settles freely in the rake area is further concentrated by the pressure of the scraper blade, gradually scraped towards the center of the pond, then enters the next layer pond through the mudding slot. The clear water is entered into the lowest layer for washing the material through the distribution box, the bottom of the overflow is returned to the upper layer for washing the material through the distribution box. The overflow of the first layer is discharged through the downflow dam, and the material after two times of washing is discharged through the bottom.

In a gold mine carbon slurry processing plant undertaken by Xinhai in Tanzania, Africa, two ordinary washing thickeners were originally used for countercurrent washing, but due to the replacement of many equipment, the space was limited, and Xinhai's double-layer (three-layer) was used. The washing thickener does not have a particularly large difference in washing effect and production efficiency, but the problem of small footprint and insufficient space is well solved, and the production cost is also effectively controlled.
