1. PAINPOINT DRIVEN OPENING

Are you scaling your alluvial or placer gold operation and finding that your washing and recovery processes are the bottleneck? Operational managers and engineering contractors face significant challenges when upgrading to 500 TPH throughput. Common pain points include:
Inconsistent Recovery Rates: Variable feed material leads to gold losses, especially fine gold, directly impacting revenue. A 2% loss on a 500 TPH plant can equate to substantial annual value.
Excessive Downtime & Maintenance: Poorly constructed trommels and scrubbers require frequent liner changes and unplanned stops, crippling your availability targets and increasing labor costs.
High Water & Power Consumption: Inefficient design leads to unsustainable resource use, escalating operational expenses and complicating permits in watersensitive regions.
Difficulty Handling ClayBound Material: Sticky clay causes blinding and reduces screening efficiency, forcing throughput below design capacity and requiring costly pretreatment.
Complex Integration & Footprint: Modular components that don’t interface smoothly create installation delays, require excessive space, and increase civil works costs.

Is your current setup compromising your plant’s profitability through lost metal, high operating costs, and unreliable performance? The solution requires a system engineered for efficiency, durability, and maximum recovery at scale.

2. PRODUCT OVERVIEW

The Oem 500 TPH Gold Mining Washing Plant is a complete, modular processing system designed for highvolume alluvial and eluvial gold deposits. It integrates feeding, washing, scrubbing, screening, and gravity concentration into a continuous operation to efficiently liberate and recover gold from gravels, sands, and claybound ore.

Operational Workflow:
1. Feed & Primary Scrubbing: Runofmine material is fed into a heavyduty trommel scrubber where it is aggressively washed and disaggregated.
2. Sizing & Classification: The scrubbed material is screened; oversize (waste rock) is ejected via conveyor, while undersize (goldbearing sands/gravels) reports to the next stage.
3. Secondary Washing & Concentration: The undersize fraction is processed through sluices or jigs for primary gold recovery. Fine material may report to a dedicated fine recovery system (optional).
4. Tailings Management & Water Handling: Waste streams are managed via slurry pumps or conveyors; process water is typically sent to a settling pond or clarification system for recirculation.

Application Scope & Limitations:
Scope: Ideal for alluvial/placer deposits, riverine operations, and eluvial weathered deposits with high clay content. Suited for greenfield installations or expansion projects requiring robust, highcapacity processing.
Limitations: Not designed for hard rock (lode) ore requiring crushing or chemical leaching processes. Feed size is typically limited by trommel dimensions (e.g., <250mm). Performance is contingent on proper feed consistency and water supply.
