Title: HighCapacity, HighRecovery 500 TPH Gold Mining Washing Plant | Engineered for Maximum Uptime and ROI

1. PAINPOINT DRIVEN OPENING

Are you scaling up alluvial or eluvial gold operations but facing bottlenecks in your material handling and recovery circuit? In hightonnage scenarios, inefficient washing and scrubbing directly translate to lost revenue. Common challenges include:
Inconsistent Feed Handling: Variable clay content and oversized material can cause frequent blockages in scrubbers and screens, leading to unplanned downtime that costs thousands per hour.
Inefficient Liberation: Inadequate scrubbing fails to break down cemented agglomerates, trapping fine gold and reducing overall recovery rates.
High Water & Power Consumption: Legacy plants often use inefficient pump systems and lack water recycling integration, escalating operational costs in remote sites.
Maintenance Intensity: Poorly designed components with high wear rates require constant attention, diverting skilled labor from critical tasks.

Is your current setup capable of processing 500 tonnes per hour reliably while maximizing gold recovery and controlling operational expenses?

2. PRODUCT OVERVIEW

This 500 TPH Gold Mining Washing Plant is a complete, modular processing system designed for the primary washing, scrubbing, screening, and gravity concentration of alluvial and eluvial goldbearing ores. It is engineered to transform raw, unsorted feed into concentrated material for final gold extraction.

Operational Workflow:
1. Primary Feed & Scrubbing: Runofmine material is fed into a heavyduty scrubber for aggressive clay breakdown and ore liberation.
2. Sizing & Classification: The scrubbed output passes over vibrating screens to separate oversize waste (e.g., +75mm) and classify the valuable fraction.
3. Primary Concentration: The undersize screen material is routed through a series of highcapacity sluices or jigs for primary gravity gold recovery.
4. Tailings Management & Water Recycling: Waste streams are managed via cyclones or dewatering screens, with process water clarified and recirculated to minimize fresh water demand.

Application Scope & Limitations:
Ideal For: Largescale alluvial/eluvial deposits, riverine operations, and weathered saprolite materials with high clay content.
Not Suitable For: Hard rock (lode) ore processing requiring crushing or chemical leaching within this circuit.
