1. PAINPOINT DRIVEN OPENING

Are you managing a largescale gold operation where consistent throughput and recovery are compromised by inefficient material handling and separation? Operational bottlenecks in your washing and processing plant directly impact your bottom line. Consider these common challenges:
Inconsistent Feed & Throughput: Variable clay content or oversize material can choke traditional scrubbers, leading to unplanned downtime and failure to meet the 500 TPH design capacity, costing thousands per hour in lost production.
Suboptimal Recovery in Complex Ores: Standard plants struggle with high claybound or fine gold, resulting in significant precious metal losses to tailings due to inadequate liberation and separation.
Excessive Water & Power Consumption: Inefficient pump systems, screening, and sluicing circuits lead to unsustainable operational costs and complicate water management in waterscarce regions.
High Maintenance & Component Wear: Abrasive feed material accelerates wear on liners, trommel screens, and pump impellers, increasing part replacement frequency and maintenance labor costs.
Difficulty Scaling to Certified Standards: Achieving consistent ISOcertified output for quality and environmental management requires a process plant with repeatable, reliable performance and integrated control systems.

Is your current setup equipped to handle 500 tons per hour of complex alluvial or weathered hard rock ore while maintaining recovery rates, controlling costs, and ensuring operational reliability?

2. PRODUCT OVERVIEW

The ISO Certified 500 TPH Gold Mining Washing Plant is a complete, modular processing system engineered for highvolume alluvial, eluvial, and weathered hard rock gold deposits. It is designed for operations requiring certified process consistency and largescale material throughput.

Operational Workflow:
1. Primary Feed & Scrubbing: Runofmine (ROM) material is fed into a robust scrubbing module (trommel or drum scrubber) for aggressive attritioning to break down clays and conglomerates.
2. Sizing & Waste Rejection: Washed material is precisely screened to remove oversize waste rock (+75mm typical). The undersize reports to the primary concentration circuit.
3. Primary Concentration: Highcapacity centrifugal concentrators or jigs efficiently recover coarse and fine gold from the screened slurry, achieving primary recovery rates exceeding 95%.
4. Tailings Management & Water Recycling: The gangue (tailings) is dewatered via cyclones or linear screens. Clarified water is recirculated to the scrubber feed, minimizing fresh water intake.
5. Security & Refining (Optional): A secure room houses concentrator bowls for final cleaning, with optional downstream smelting or intensive leaching modules for direct doré production.

Application Scope: Ideal for largescale placer operations, alluvial concessions, and surface deposits with high clay content. Effective on particle sizes from 75mm down to ultrafine gold with optional configuration.

Limitations: Not designed for primary hard rock crushing/grinding of unweathered sulphide ores. Requires a consistent feed of liberated or liberatable gold. Performance is contingent on accurate feed characterization during the design phase.
