1. PAINPOINT DRIVEN OPENING

Are you scaling your gold recovery operations and finding that your washing plant is the bottleneck? Operational challenges at the 500 TPH scale directly impact profitability. Common issues include:
Inconsistent Feed Handling: Fluctuations in feed grade and particle size distribution can overwhelm static systems, leading to gold loss in fines or blockages in scrubbers.
Excessive Water & Power Consumption: Inefficient screening and sluicing designs at high throughputs result in unsustainable utility costs, eroding margins.
High Maintenance Downtime: Poorly constructed trommels, screens, and slurry pumps require frequent, unplanned stoppages for repair and liner replacement.
Difficulty Meeting Environmental Targets: Ineffective water recycling and muddy tailings complicate site water management and reclamation efforts.

Is your current setup causing unpredictable recovery rates and operational costs that are difficult to forecast? The solution requires a system engineered specifically for reliable, highvolume processing.

2. PRODUCT OVERVIEW

A 500 TPH Gold Mining Washing Plant is a complete modular processing system designed for alluvial or eluvial deposits. Its primary function is to scrub, classify, and concentrate raw material to produce a heavy mineral concentrate for further gold extraction. The operational workflow is a continuous process:
1. Primary Feed & Scrubbing: Runofmine material is fed into a robust scrubbing section (typically a trommel or scrubber) to break down clayey matrices and liberate gold particles.
2. Particle Size Classification: The scrubbed output passes over vibrating screens or trommel panels to separate oversize waste rock (+10mm to +75mm, depending on deposit) from the valuable fine fraction.
3. Gravity Concentration: The undersize slurry reports to a series of highcapacity gravity concentrators (e.g., centrifugal concentrators, sluices) to separate heavy minerals, including gold, from lighter gangue material.
4. Tailings Management & Water Recycling: Waste tailings are conveyed to a settling area, while process water is clarified and recirculated to minimize fresh water intake.

Application Scope & Limitations: This plant type is optimal for freemilling alluvial/placer deposits with minimal clay content. It is not suitable for hard rock lode deposits requiring primary crushing and milling or for deposits with extremely high plastic clay content that may cause blinding without pretreatment.
