Centrifugal Gold Concentrator for Fine Gold Recovery
Product Information
The Batch Centrifugal Gold Concentrator is designed for applications requiring high concentration ratios and recovery of gravity-recoverable free gold. During operation, feed continuously enters the concentrator while valuable heavy minerals accumulate in the bowl's concentration zone. After a preset concentration period, feed is stopped and the retained concentrate is discharged during a rinse cycle. This configuration is suitable for free gold recovery, grinding circuit gravity recovery, placer gold processing and small- to medium-scale gold plants. Because the system can produce a relatively small quantity of high-grade concentrate from a larger feed stream, it can reduce the amount of material requiring subsequent cleaning and upgrading.
High centrifugal force significantly increases the effective separation force compared with conventional gravity concentration. Commercial enhanced-gravity equipment can operate across a broad G-force range depending on the model and application.
The centrifugal field helps recover fine liberated gold and other dense minerals that may be difficult to capture using conventional low-G equipment. Actual recovery depends on mineral liberation, particle size, feed density, bowl configuration and operating parameters.
The separation process is based on physical density differences rather than chemical reagents. No mercury or cyanide is required for the gravity concentration stage, making the equipment suitable for environmentally conscious mineral processing circuits.
Batch centrifugal concentrators can produce a relatively small quantity of high-grade concentrate from a much larger feed stream. This reduces the volume of material requiring downstream cleaning and upgrading.
The concentrator can be integrated with trommel screens, vibrating screens, hydrocyclones, pumps, ball mills, flotation circuits, shaking tables and other mineral processing equipment to form a complete gravity recovery circuit.
