1. PAINPOINT DRIVEN OPENING

Are you scaling your alluvial or hard rock gold operation and finding your recovery process is the bottleneck? Managing a 500 TPH feed rate presents distinct challenges that directly impact profitability. Common operational hurdles include:
Inconsistent Recovery Rates: Inefficient scrubbing and screening of claybound materials can lead to significant gold losses in the fines, directly reducing revenue.
Excessive Downtime & Maintenance: Poorly constructed trommels and scrubbers require frequent liner changes and repairs, halting your entire processing line for costly, unplanned maintenance.
High Water & Power Consumption: Inefficient pump systems and drive mechanisms inflate operational expenses, eroding margins in waterscarce or remote sites.
Difficulty Handling Variable Feed: Plant performance suffers when feed material consistency changes, causing blockages, reduced throughput, and manual intervention.

Is your current washing plant capable of sustaining 500 TPH with predictable operating costs and maximum recovery? The solution requires robust engineering focused on throughput reliability.

2. PRODUCT OVERVIEW

The 500 Tph Gold Mining Washing Plant is a heavyduty, modular processing system designed for highvolume alluvial and eluvial deposits. Its primary function is to liberate gold from clay, gravel, and ore through aggressive scrubbing, precise size classification, and efficient concentration.

Operational Workflow:
1. Primary Feed & Scrubbing: Runofmine material is fed into a robust trommel scrubber, where lifters and highpressure water jets break down clays and agglomerates.
2. Size Classification: The trommel screen separates material into oversize (waste), midsize (for secondary scrubbing or direct concentration), and undersize (slimes).
3. Secondary Processing & Concentration: Correctly sized ore reports to vibrating decks or jigs for primary gravity concentration, while midsize material may undergo further attrition in a scrubber barrel.
4. Tailings Management & Water Handling: Efficient slurry pumps transfer tailings, while water recirculation systems are integrated to minimize fresh water consumption.

Application Scope: Ideal for largescale placer mining operations, alluvial gold projects, and eluvial deposits with high clay content. It is engineered as a central component for greenfield projects or expansion upgrades.

Limitations: This plant is not designed for primary hard rock crushing or fine chemical leaching processes. Optimal performance requires adequate feed preparation (size reduction) and a consistent water supply.
