1. PAINPOINT DRIVEN OPENING

Scaling your gold recovery operation to 500 Tph presents distinct challenges that directly impact profitability. Are you experiencing:
High Operational Downtime: Frequent clogging in scrubbers or screens from claybound material, leading to costly hourly production losses.
Inconsistent Recovery Rates: Variable feed material causing gold losses in fines or inefficient separation, directly reducing revenue per ton processed.
Excessive Water & Power Consumption: Inefficient washing and screening loops consuming disproportionate resources, eroding margin in remote locations.
High Maintenance Burden: Constant wear on components from abrasive feeds and inadequate material handling, increasing spare parts costs and labor hours.
Scalability Limitations: A plant that cannot handle peak feed volumes or adapt to changing ore body characteristics, capping your operation’s potential.

The central question for plant managers is: how do you achieve reliable, highvolume throughput with predictable operating costs and maximized recovery? The answer lies in a purposeengineered 500 Tph gold mining washing plant.

2. PRODUCT OVERVIEW

This solution is a complete, modular gold mining washing plant engineered for alluvial and eluvial deposits. It is designed for primary scrubbing, clay breakdown, screening, and gravity concentration preconcentration at a nominal 500tonperhour throughput.

Operational Workflow:
1. Primary Feed & Scrubbing: Runofmine (ROM) material is fed into a robust scrubbing system designed to break down clay agglomerates and dissolve cemented materials.
2. Sizing & Classification: The scrubbed ore passes through vibrating screens to separate +2mm to +10mm (configurable) oversize (gravel/pebbles) from the valuable fine fraction.
3. Slurry Concentration & Gold Recovery: The undersize slurry, containing liberated gold, is routed to a series of highcapacity gravity concentrators (e.g., centrifugal concentrators) for primary gold recovery.
4. Tailings Management & Water Handling: Efficient dewatering of tailings and closedloop water recycling systems are integrated to minimize environmental footprint and water consumption.

Application Scope & Limitations:
Scope: Ideal for alluvial/placer deposits, eluvial weathered ore, and saprolitic claybound ores requiring intensive washing. Serves as the primary beneficiation step before further processing or direct smelting of concentrates.
Limitations: Not suitable for hard rock (lode) ore without prior crushing. Performance is contingent on accurate feed characterization regarding clay content, moisture, and particle size distribution.
