gold mining alluvial equipment

Addressing Your Alluvial Gold Recovery Challenges

Are you facing diminishing returns from your placer deposits? The operational realities of alluvial gold mining present distinct hurdles that directly impact your profitability. Consider these common challenges:

• Low Recovery Rates: Fine and flake gold escapes traditional sluices and jigs, with industry estimates suggesting 15-30% of payable gold can be lost to tailings, representing a significant revenue drain.
• High Operational Downtime: Constant manual cleanup periods, screen blockages, and component wear in abrasive environments halt production. How many hours of potential processing time do you lose each week to maintenance?
• Excessive Water and Power Consumption: Inefficient separation systems require high-volume water pumps and powerful motors, escalating your operational expenses in remote locations.
• Labor-Intensive Concentration: The need for frequent manual panning of concentrates or cleaning of carpets adds labor costs and introduces consistency variables.
• Difficulty in Site Deployment: How quickly can you mobilize or demobilize your processing plant between seasonal deposits or across dispersed alluvial fields?

What if your gold mining alluvial equipment was engineered to directly mitigate these costs and complexities?

Product Overview: Advanced Alluvial Gold Recovery Plants

Our solutions are modular, high-recovery wash plants designed for the efficient extraction of gold from alluvial (placer) deposits. These systems are engineered for operators requiring high volume throughput with maximum recovery of both coarse and fine gold particles.

Operational Workflow:

1. Feed & Scrubbing: Run-of-mine material is fed into a robust scrubber or trommel, where it is washed and broken down to liberate gold-bearing ore.
2. Primary Concentration: The screened slurry passes through a primary concentration unit, such as a centrifugal concentrator or jig, to capture the majority of the coarse and medium gold.
3. Secondary Fine Recovery: A dedicated secondary system, often a sluice or additional concentrator, targets fine gold particles that bypass the primary stage.
4. Tailings Management: Efficiently processed waste material is stacked for site rehabilitation.

Application Scope & Limitations:
This equipment is optimal for unconsolidated deposits including riverbeds, flood plains, and bench deposits. It is less suited for hard-rock (lode) sources without primary crushing or for clay-bound materials lacking adequate pre-scrubbing. Particle size typically handles up to 100mm.
