Key Gravity Separation Equipment for Placer Gold Ore Processing

I. Jig Machine

The jig machine is a core piece of equipment for the roughing stage of placer gold ore. It utilizes a pulsed water flow principle to stratify mineral particles by density. High-density gold particles rapidly settle to form concentrate, while low-density gangue is carried away by the water flow. This equipment offers large processing capacity and high recovery rates, making it suitable for placer gold beneficiation operations of various scales.

II. Vibrating Sluice Box

The vibrating sluice box is an efficient device for recovering fine gold particles. vibrating sluice box creates continuous undulations in the water flow, making it particularly suitable for processing clay-rich placer gold ore. The vibrating sluice box accelerates the settlement of fine gold within the riffles and features simple operation and low maintenance costs.

III. Centrifugal Concentrator

The centrifugal concentrator is specifically designed to process tailings from jigging machines and shaking chutes. It utilizes a high-speed rotating centrifugal force field to concentrate fine gold particles against the inner wall of the rotating drum. The centrifugal concentrator shows remarkable effectiveness in recovering very fine gold particles (below 200 mesh), effectively reducing gold losses and improving the overall recovery rate.

IV. Shaking Table

The gold shaking table serves as the final cleaning equipment. Through its unique deck design and asymmetrical reciprocating motion, it further purifies the gold concentrate. The shaking table can produce high-grade gold concentrate.

In the placer gold ore beneficiation process, a combination of the above gravity separation equipment is often employed. This approach ensures both high recovery rates and a high-grade concentrate.
