1. PAINPOINT DRIVEN OPENING

Are you scaling up your alluvial or eluvial gold operation and finding that your washing and recovery setup is the bottleneck? Operational inefficiencies in highcapacity material scrubbing and gold liberation directly impact your bottom line. Common challenges with 500 TPH throughput 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 in lost production.
Inefficient Liberation & Recovery: Inadequate scrubbing fails to break down cemented agglomerates, trapping fine gold and sending payable material to your tailings. Industry estimates suggest losses of 515% are not uncommon in underperforming plants.
High Operational Costs: Excessive water consumption, high wear part replacement frequency on inferior components, and the need for a large crew to manage multiple smaller units erode profit margins.
Complex Integration: Piecing together equipment from different manufacturers for screening, scrubbing, and gravity separation creates control complexities and maintenance headaches.

Is your current plant configuration maximizing recovery at a 500tonperhour rate? Are you managing water and power consumption effectively? A purposeengineered 500 TPH gold mining washing plant is designed to address these exact operational and financial pressures.

2. PRODUCT OVERVIEW

A 500 TPH gold mining washing plant is an integrated processing system designed for the continuous scrubbing, classification, and gravity concentration of alluvial or weathered eluvial deposits. Its primary function is to liberate gold from claybound or cemented gravels and concentrate it into a manageable product for final extraction.

Operational Workflow:
1. Primary Scrubbing & Size Reduction: Runofmine feed is introduced into a heavyduty rotary scrubber, where intense attrition breaks down clays and soft conglomerates.
2. Primary Screening & Waste Removal: The scrubbed material passes over a vibrating screen. Oversize rocks (+75mm) are rejected as waste, while undersize material proceeds.
3. Secondary Screening & Classification: A second screening stage separates the valuable gravel fraction (e.g., 75mm +2mm) for further concentration.
4. Gravity Concentration: The target fraction is routed through a series of highcapacity gravity concentrators (such as centrifugal concentrators or sluices) to recover liberated gold particles.
5. Tailings Management & Water Recycling: Fine waste (2mm) reports to a settling pond or dewatering system, with clarified water recirculated to significantly reduce fresh water demand.

Application Scope & Limitations:
This plant is optimal for unconsolidated deposits with significant clay content requiring intensive agitation. It is less suitable for hardrock primary ore processing or environments with extreme space constraints where modularity is paramount over fixed installation efficiency.
