Alluvial Gold Recovery Solution

Advanced Gravity Separation & High-Clay Ore Processing

Executive Summary

Centrifugal Concentrator

Modern alluvial mining operations frequently encounter “clay-bound” deposits and ultra-fine gold particles (down to 0.074mm) that traditional sluicing methods fail to capture. The APEX integrated solution utilizes high-energy mechanical scrubbing combined with 200G centrifugal force to ensure maximum liberation and recovery, achieving industry-leading efficiency rates of up to 98%.

The Three-Stage Recovery Process

Centrifugal Concentrator

Stage 1: Disintegration & Primary Washing

Utilizing the APEX Gold Trommel Screen, high-pressure water jets and 16-20 RPM mechanical tumbling break down sticky clay matrices. This critical stage ensures gold particles are liberated from waste material before entering the concentration circuit.

Stage 2: High-G Centrifugal Concentration

The STLB Centrifugal Concentrator subjects the slurry to intense centrifugal force (up to 200G). Precision fluidization prevents the concentrate bed from compacting, allowing even refractory and fine gold to settle efficiently while flushing out lighter gangue.

Stage 3: Precision Final Refining

Resulting concentrates are processed via industrial Shaking Tables. This final gravity separation stage utilizes lateral shaking and water film stratification to produce high-purity gold sand ready for final smelting.

Centrifugal Concentrator

Technical Advantages

Fine Gold Mastery: Captures particles as small as 0.074mm, outperforming traditional gravity equipment by 30-50%.
Low Operational Cost: High-torque, low-speed motors combined with wear-resistant liners reduce power consumption and maintenance downtime.
Fully Customizable: Adjustable rotation speeds and water flow rates allow the system to adapt to specific site ore characteristics.
