1. PAINPOINT DRIVEN OPENING

Are you facing escalating operational costs and unpredictable recovery rates in your highvolume gold 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 methods can require millions of liters daily, creating significant sourcing and environmental management costs.
Inconsistent Recovery with ClayBound Material: Sticky clays can cause screen blinding and gold loss, leading to a measurable drop in overall plant yield.
Excessive Downtime for Maintenance: Poorly designed or underbuilt washing systems require frequent stoppages for screen cleaning, component wear replacement, and clog removal.
High Operational Labor Intensity: Systems requiring constant manual intervention to manage feed consistency or clear blockages drive up labor costs and introduce human error.
Suboptimal Separation Efficiency: Inadequate scrubbing and screening results in gold reporting to tails or insufficient liberation of paydirt, leaving revenue in the ground.

Is your current setup maximizing recovery per ton processed? Are you effectively balancing throughput with operational expense? The solution requires a purposebuilt system engineered for efficiency at scale.

2. PRODUCT OVERVIEW

The 500 TPH Gold Mining Washing Plant is a modular, heavyduty processing system designed for the primary washing, scrubbing, screening, and gravity concentration of alluvial and eluvial deposits. It is engineered to handle high clay content and break up cemented gravels to liberate gold effectively before downstream cyanidation or other recovery processes.

Operational Workflow:
1. Primary Feed & Scrubbing: Runofmine (ROM) material is fed into a robust log washer or rotary scrubber, where intense agitation breaks down clays and soft conglomerates.
2. Primary Screening & Size Classification: The scrubbed output passes over a vibrating screen deck, separating oversize waste rock (+75mm) from the valuable smaller fraction.
3. Secondary Washing & Desliming: The undersize material may be routed to a secondary rinsing screen or hydrocyclone bank to remove fine silts and clays (0.5mm) that can hinder recovery.
4. Concentration (Optional Integration): The cleaned +0.5mm fraction can be directly fed into integrated gravity concentrators (e.g., centrifugal concentrators, sluices) for coarse gold recovery.

Application Scope & Limitations:
Scope: Ideal for alluvial/placer deposits, eluvial materials, and weathered conglomerates with high clay content. Suited for greenfield installations or plant upgrades requiring a dedicated preconcentration wash plant.
Limitations: Not designed for hard rock (lode) ore processing without prior crushing. Performance is contingent on feed material characteristics; extreme boulder size (>1m) may require a prescalping grizzly.
