Application of Dryland Gold Separation Equipment in Gobi and Desert Areas

Dryland gold separation equipment is suitable for water-scarce or water-poor areas such as deserts and Gobi. While gold still exists primarily as native gold, a significant portion is contained in vanadium compounds. Dry gold separation primarily concentrates gold in saw concentrate and recovers it during arsenic refining. During the gravity separation process in gold mining equipment, the sinking and floating of the ore deposit is almost unrelated to the mineral density. Gravity separation in gold mines is a dry separation method based on the varying wettability of the ore. In severely arid areas like the Gobi Desert and other deserts, where water resources are severely scarce, the use of washing equipment is impossible. Therefore, we have developed a more advanced gravity gold separation system based on practical conditions, combining wind power with mechanical braking. This equipment features fully hydraulic unloading, requiring no manual operation. The electronic control system is a frequency conversion control system, a major breakthrough in gold separation technology. The entire system can be manufactured as both a mobile and a fixed unit. The entire unit is highly adaptable to temperatures as low as -50°C. The gold recovery rate exceeds 95%, and it is suitable for granular, surface, and flake gold. The entire system utilizes a two-section welded joint technology, resulting in a simple structure and a new product and technology for gold separation. Raw materials are poured into the feed hopper by construction machinery, washed with high-pressure water, and then screened and graded on a vibrating screen. Unqualified material is discharged through a waste chute into a waste pool. Fine material passes through a bottom hopper and enters a feed conveyor, which evenly feeds it into four air-separated gold shakers for fine separation. The fine material remains in the shakers, while the waste material enters a transfer hopper and is discharged to the waste area via a conveyor. Through years of production experience and user feedback, we have continuously improved and perfected this equipment, which has become a mature alluvial gold dry separation system. This gold separation system boasts a high processing capacity, low equipment failure rate, easy maintenance and repair, and simple operation, making it highly popular among users both domestically and internationally.

This entire system was developed with environmental protection and recycling in mind. This gravity separation system is a new, highly efficient gold separation system favored by numerous mineral processing customers. Since its launch, this gold separation system has been exported to Outer Mongolia, Russia, South Korea, South Africa, Sudan, and other countries, receiving unanimous praise. The company also has a mineral separation test machine, and we welcome you to conduct gold separation experiments with ore samples. Dryland gold mining equipment – Mobile dryland gold mining vehicles are a key component of gold mining machinery. This new waterless gold mining equipment, developed by our company after years of continuous experimentation and improvement based on our traditional sled-type dry/air separation equipment, overcomes the heavy weight and awkward steering associated with sled-type dry separation equipment and is suitable for most mining locations with no or limited water.

The mobile dryland gold mining vehicle is wheel-mounted and features hydraulic and mechanical leveling, which can be configured according to user requirements. This mobile land-based gold mining equipment boasts a compact structure, strong integrity, lightweight, high throughput, simple operation, reliable operation, easy maintenance, and easy portability. This machine combines the separation principles and features of a fixed chute and a jig, overcoming the compaction problem of fixed chutes. It utilizes dual recovery channels to separate fine gold from coarse gold and flake gold, significantly improving gold recovery. With a 10-hour separation cycle, the gold concentrate yield is 0.1%, with a recovery rate exceeding 94%, and operates at a rate of 100-500 t/h.
