Gold Concentrator

A gold concentrator, specifically the centrifugal gold concentrator, is a high-efficiency mineral processing device designed to recover fine and ultra-fine gold particles from ore slurries. Leveraging centrifugal force to enhance gravity separation, it addresses the challenge of capturing small gold particles that traditional gravity methods (such as sluice boxes or shaking tables) often miss.

It is widely used in both artisanal and industrial gold mining, centrifugal gold concentrators have become a cornerstone of modern gold recovery due to their compact size, high throughput, and ability to process low-grade ores effectively.

Versatile Tools In Gold Recovery

Centrifugal gold concentrators are versatile tools in gold recovery, with applications across various mining scenarios:

● Primary gold recovery:

They process ore slurries directly after grinding, capturing fine gold particles in both free-milling and refractory ores (ores where gold is locked in sulfides or oxides).

● Secondary recovery:

They reprocess tailings from other separation processes (e.g., ball mills, flotation cells) to recover residual gold, improving overall ore utilization.
Gold Ore Processing

● Alluvial gold processing:

They handle placer deposits (loose sediments containing gold) by separating fine gold from sand, gravel, and clay in riverbeds or beaches.

● Low-grade ore processing:

Their ability to concentrate gold from dilute slurries makes them effective for low-grade ores, which are otherwise uneconomical to process with traditional methods.

Material Application

1. Alluvial Gold Mining

● Feed Material: Placer gold ores (-2mm) containing free gold particles, including river sands, floodplain deposits, and beach placers with varying clay content
● Recovery Rate: Up to 95% for particles >10 microns,

2. Hard Rock Gold Processing

● Feed Material: Milled ore (-74μm/200 mesh) from quartz veins, sulfide ores, and oxidized deposits, preferably with 80% passing 100 mesh for optimal performance
● Recovery Rate: 85-95% for free gold particles

3. Tailings Re-processing

● Feed Material: Gravity tailings from other processes including old sluice tailings, shaking table rejects, and jig concentrates with gold content typically 0.5-3 g/ton
● Recovery Rate: 30-60% of remaining gold

4. Placer Gold Cleanup

● Feed Material: Concentrates from sluice boxes or jigs, with heavy mineral content of 10-30%
● Recovery Rate: Up to 98% of fine gold between 20-300 microns
