1. PAINPOINT DRIVEN OPENING

Are you facing escalating operational costs and unpredictable recovery rates in your highvolume gold mining operation? Managing a 500 TPH throughput presents distinct challenges that directly impact your bottom line. Common pain points include:

High Water Consumption & Tailings Management: Traditional washing plants can use over 1,500 cubic meters of water per hour, creating massive settling pond requirements and environmental compliance costs.
Frequent Downtime for Maintenance: Standard scrubbers and trommels with thin shells or inferior bearings require frequent stoppages for liner replacement and mechanical repairs, costing hundreds of production hours annually.
Inefficient Fines Recovery: Significant gold loss in the 1mm fraction due to inadequate scrubbing action or poor sluice/screen configuration represents a direct revenue leak.
High Operational Manning: Plants requiring constant manual adjustment of water flow, feed rates, and monitoring of multiple failure points increase labor costs and operational risk.
Difficulty Handling Variable Feed Material: Claybound ore or changes in feedstock density can choke standard systems, leading to prolonged cleanup cycles and reduced average throughput.

Is your current setup delivering the consistent, costperton efficiency required for profitable 500 TPH gold mining? The solution lies not just in capacity, but in intelligent, robust engineering designed for continuous heavyduty operation.

2. PRODUCT OVERVIEW

The OEM 500 TPH Gold Mining Washing Plant is a complete, modular processing system engineered for the primary washing, scrubbing, screening, and gravity concentration of alluvial or eluvial goldbearing material. It is designed to handle high clay content and produce a concentrated slurry for downstream extraction.

Operational Workflow:
1. Primary Feed & Scrubbing: Runofmine (ROM) material is fed into a heavyduty doublescreen scrubbing trommel, where intense attrition breaks down clay agglomerates and liberates gold.
2. Sizing Separation: The trommel performs precise separation into multiple size fractions (e.g., +30mm waste rock, 30mm+5mm gravels for secondary scrubbing/concentration, 5mm slurry).
3. Fines Concentration: The critical 5mm slurry containing fine gold reports to a series of cascading sluices or enhanced gravity concentrators within the circuit to maximize recovery.
4. Waste Handling: Oversize waste is conveyed to a separate stockpile, while tailings are managed via an integrated dewatering system to reduce water loss and pond footprint.

Application Scope & Limitations:
Scope: Ideal for largescale alluvial/eluvial deposits, riverine operations, and old tailings reprocessing projects requiring highvolume clay breaking and gold liberation.
Limitations: Not suitable for hard rock (lode) ore processing without prior crushing. Feed size is typically limited to 250mm. Optimal performance requires a consistent feed rate managed by upstream equipment.
