1. PAINPOINT DRIVEN OPENING

Scaling gold recovery operations to 500 Tph presents distinct challenges that directly impact profitability. Plant managers and engineering contractors often face:
High Operational Downtime: Frequent clogging in scrubbers and screens from sticky clay or oversize material halts entire processing lines, costing thousands per hour in lost production.
Inconsistent Recovery Rates: Variable feed material can overwhelm static washing systems, leading to goldbearing fines bypassing recovery circuits and reporting to tailings.
Excessive Water & Power Consumption: Inefficient pump systems and material handling in highcapacity plants create unsustainable utility costs, eroding project margins.
Rapid Component Wear: Abrasive feed at this volume degrades standard liners, screens, and piping, resulting in high maintenance costs and unpredictable replacement schedules.
Complex Commissioning & Integration: Sourcing a plant from multiple vendors leads to coordination failures, design gaps, and prolonged timetooperation.

Are you managing these risks? The solution lies in a singlecontract, engineered system designed for reliability at scale.

2. PRODUCT OVERVIEW

This product is a complete, skidmounted or modular 500 Tph Gold Mining Washing Plant. It is engineered as a turnkey solution for alluvial and eluvial deposits, designed to process raw feed material into concentrated ore ready for final gold recovery (e.g., via gravity concentrators or direct cyanidation).

Operational Workflow:
1. Primary Feed & Scrubbing: Runofmine (ROM) material is fed into a robust trommel or scrubber for disaggregation and initial washing.
2. Sizing & Waste Removal: Oversize rocks (+75mm) are ejected via conveyors. Midsize gravels are typically routed to secondary crushing or waste stockpiles.
3. Critical Clay & Fines Processing: The sub75mm fraction passes through vibrating screens with highpressure spray bars to break down clay matrices.
4. Primary Concentration: The liberated sand and gold fraction reports to primary concentration units (e.g., jigs, spirals) for initial upgrade.
5. Tailings Management & Water Handling: Waste streams are managed via slurry pumps; process water is recirculated through a compact clarification system.

Application Scope & Limitations:
Scope: Ideal for alluvial/placer deposits, weathered eluvial materials, and old tailings reprocessing with moderate clay content.
Limitations: Not suitable for hard rock (lode) ore without prior crushing. Feed material size distribution must be evaluated; excessive boulders (>500mm) may require a prescalping circuit.
