1. PAINPOINT DRIVEN OPENING

Are you scaling your alluvial or hard rock gold operation and facing the critical bottlenecks of midtohighcapacity processing? Managing a 500 TPH feed rate exposes significant pain points that directly impact your bottom line. Inefficient gold recovery at this scale leads to substantial revenue loss with every ton processed. High water consumption creates both environmental compliance challenges and escalating operational costs. Frequent component wear in abrasive environments results in unplanned downtime and high maintenance expenses, while inconsistent feed material can cause process upsets and reduce overall plant availability. Are you struggling to balance throughput targets with recovery efficiency? Is your current washing and screening setup failing to deliver the consistent, reliable performance required for profitable 500 TPH operation? The solution requires a purposeengineered system designed for highvolume, highavailability processing.

2. PRODUCT OVERVIEW

This is a complete, OEMengineered 500 TPH Gold Mining Washing Plant, a modular processing system designed for the primary washing, scrubbing, screening, and gravity concentration of goldbearing alluvial or eluvial deposits. The plant is engineered to handle high clay content and weathered ore, liberating gold for efficient recovery.

Operational Workflow:
1. Primary Feed & Scrubbing: Runofmine (ROM) material is fed into a robust scrubber or trommel, where intense agitation breaks down clay matrices and dissolves contaminants.
2. Sizing & Classification: The disaggregated material reports to vibrating screens, separating +2mm to +10mm (configurable) oversize (waste) from valuable undersize.
3. Slurry Concentration & Gold Recovery: The undersize slurry is routed to a series of concentrators, such as centrifugal concentrators or sluices, where highgrade gravity concentrate is produced.
4. Tailings Management & Water Handling: Waste tailings are conveyed to a designated area, while process water is typically sent to a settling pond or clarification system for recycling.

Application Scope: Ideal for largescale alluvial gold projects, riverine deposits, and weathered saprolite zones with moderate clay content.
Limitations: Not suitable for primary hard rock processing requiring crushing circuits or for ultrafine (sub100 micron) gold recovery without additional downstream circuit integration (e.g., flotation or cyanidation).
