1. PEMBUKAAN PAINPOINT DRIVEN

Are you facing persistent bottlenecks in your gold recovery circuit that directly impact your bottom line? Untuk pengurus loji dan kontraktor kejuruteraan, the challenges of fine gold recovery are often quantified in measurable losses: inefficient capture of sub100micron particles leading to tailings grade slippage, excessive downtime for concentrate cleanup and equipment maintenance, and high operational costs from water consumption and reagent use. These issues translate to a direct erosion of profit margins. How do you increase recovery rates without a proportional increase in energy or labor costs? Can you improve the security and efficiency of your final concentrate handling? Is your current setup adaptable to fluctuating feed grades and ore types? Addressing these operational challenges requires a targeted approach to gravity concentration and final recovery.

2. GAMBARAN KESELURUHAN PRODUK

This product line encompasses engineered centrifugal concentrators for the highvolume recovery of free gold, particularly fine gold, from alluvial and hard rock processing plants. As a critical component in modern gravity circuits, this equipment is designed for continuousduty operation in rough industrial environments.

Aliran Kerja Operasi:
1. Pengenalan suapan: Slurry, typically screened to 2mm or 6mm, is introduced under controlled pressure.
2. Centrifugal Concentration: The slurry enters a rapidly spinning drum, where enhanced gravitational forces (biasanya 50200 G's) separate highdensity gold particles from lighter gangue material.
3. Continuous Concentration: Gold and heavy minerals are trapped behind engineered riffles or grooves, while tailings are fluidized and discharged continuously.
4. Automated Concentrate Removal: At programmed intervals, the system halts rotation and flushes the concentrated heavies into a secure collection vessel, minimizing manual handling.
5. Cycle Resumption: The process restarts automatically, ensuring nearcontinuous operation with brief purge cycles.

Skop Permohonan & Batasan:
Skop: Ideal for primary gravity recovery in alluvial operations, as a scavenger unit after grinding mills in hard rock plants, or for upgrading existing concentrate. Effective on free gold particles from several millimeters down to ~10 microns.
Batasan: Not effective for chemically bound (refractory) gold or ultrafine particles without preclassification. Performance is dependent on proper feed preparation (sizing/desliming) and consistent slurry density control.
