The selection of equipment for placer gold mining is crucial. Choosing the wrong equipment not only results in low recovery efficiency but also easily leads to gold loss in tailings. To improve the recovery rate, it is essential to have a good understanding of various placer gold beneficiation equipment. Let’s take a closer look at the key equipment that can enhance the recovery rate of placer gold deposits.

01 Trommel Screen

The trommel screen is essential for processing clay-rich placer gold deposits. Through the rotation of the drum and the action of scraper blades, it breaks up clay clumps, releasing trapped gold particles.

The trommel screen removes large impurities and ensures material of the appropriate size proceeds to the subsequent gravity separation process, preventing blockages.

02 Sawtooth Wave Jig

The sawtooth wave jig is an improved version of the traditional jig, commonly used for the rough concentration of placer gold.

It features high recovery rates, large processing capacity, and a wide range of applicable particle sizes. For low-grade placer gold deposits, using the sawtooth wave jig for pre-concentration and waste removal is an excellent choice.

03 Pulsating Sluice

The pulsating sluice is particularly effective for recovering gold from highly viscous placer deposits. The continuous undulating motion of the slurry in the pulsating sluice allows more opportunities for gold particles to settle into the gaps.

It can recover both granular and flaky gold, as well as fine gold particles and "flour gold" smaller than 0.02mm.

04 Centrifugal Concentrator

Under the powerful centrifugal force generated by the centrifugal concentrator, fine gold particles, due to their high density, accumulate on the inner wall of the rotating drum, while lighter impurities are washed away by the reverse flushing water.

The centrifugal concentrator is highly effective in recovering fine gold particles that are difficult to capture with other equipment. In placer gold processing, it is often used for recovering gold from tailings of jigs or sluices.

05 Gold Shaking Table

The gold shaking table, also known as the Gemini table, is specifically designed for low-grade gold ores. Its uniquely optimized groove structure excels at capturing fine gold particles, significantly improving gold recovery rates and concentrate grade.
