Centrifugal Gold Concentrator for Fine Gold Recovery
Product Information
For hard rock gold processing plants, the Centrifugal Gold Concentrator can be installed around the grinding and classification circuit to recover liberated free gold at an early processing stage. Typical installation points include ball mill discharge, cyclone feed, cyclone underflow, grinding circuits and gravity concentration circuits. Early recovery of gravity-recoverable gold can help reduce the amount of valuable material entering downstream process streams. The enhanced gravity principle provides a practical method for concentrating dense mineral particles without chemical reagents during the gravity separation stage. The final equipment configuration should be selected according to feed capacity, particle size, solids concentration, mineral liberation characteristics and the existing process flow.
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.
