1. PAINPOINT DRIVEN OPENING

Are you scaling up alluvial or placer gold operations but finding that traditional washing and recovery methods are creating bottlenecks? Operational inefficiencies at high throughputs directly impact your bottom line. Consider these common challenges:
Inconsistent Recovery Rates at Scale: Lower recovery percentages on fine gold and nuggets when processing 500 Tph of material can mean thousands of dollars in lost revenue per day.
Excessive Downtime for Maintenance: Poorly designed plants with abrasive wear points require frequent shutdowns, halting your entire production line.
High Water and Power Consumption: Inefficient scrubbing and screening processes lead to unsustainable utility costs, especially in remote sites.
Difficulty Handling ClayBound Material: Sticky clay can blind screens and reduce classification efficiency, drastically cutting effective capacity.
Rapid Capital Depreciation: Equipment that cannot withstand 24/7 mining cycles suffers from premature failure, demanding earlier replacement.

Is your current setup equipped to deliver consistent, costeffective tonnage while maximizing gold recovery? The solution requires a plant engineered specifically for highvolume, continuous operation.

2. PRODUCT OVERVIEW

The 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 deposits. It transforms raw, excavated feed into concentrated heavy mineral sands ready for final gold extraction.

Operational Workflow:
1. Primary Feed & Scrubbing: Runofmine material is introduced into a robust scrubber for aggressive agitation, breaking down clay conglomerates and dissolving dirt from rocks and gold.
2. Sizing & Classification: The discharged slurry passes over vibrating screens to separate +2mm to +10mm (configurable) oversize (gravels) from the valuable fines fraction.
3. Slurry Distribution & Gravity Concentration: The undersize slurry, containing liberated gold, is evenly distributed to a bank of highcapacity centrifugal concentrators for primary gold recovery.
4. Tailings Management & Water Handling: Waste tailings are conveyed away, while process water is channeled to a settling/recycling system to minimize fresh water intake.

Application Scope & Limitations:
Scope: Ideal for largescale placer/alluvial gold operations, river dredging projects, and ancient riverbed deposits. Effective on a range of materials from sandy gravels to moderately claybound ore.
Limitations: Not suitable for hard rock (lode) ore requiring crushing or chemical (cyanide) processing. Feed material size is typically limited to under 250mm.

6. APPLICATION SCENARIOS

LargeScale Alluvial Mine Expansion

Challenge A West African mining company needed to increase processing capacity from 200 Tph to 700 Tph but faced space constraints and high water costs.
Solution Implementation of two modular 500 Tph Gold Mining Washing Plants configured in parallel with a shared water recycling system.
Results Achieved combined throughput of over 1000 Tph within the existing site footprint. The closedloop water system cut freshwater procurement costs by 60%, paying back the investment within 14 months.

ReTreatment of Old Tailings Dams

Challenge An operation in South America sought to recover residual gold from historical tailings but found existing equipment recovered only coarse gold inefficiently.
Solution A single 500 Tph plant was configured with an extended scrubber section and specialized screen decks tailored to the fine, degraded material profile.
Results The plant achieved 96% recovery on the sub100 micron gold fraction that previous equipment missed, turning a liability into a profitable operation with minimal waste handling required.
