1. PAINPOINT DRIVEN OPENING

Are you scaling your alluvial or placer gold operation and hitting critical bottlenecks? A 500 TPH throughput target exposes systemic inefficiencies that directly erode profit margins. Common challenges include:

Inconsistent Recovery Rates: Variable feed material leads to gold losses in fines or to tailings, with each percentage point lost representing significant annual revenue forfeiture.
Excessive Downtime & Maintenance: Poorly designed washing plants with inadequate material handling cause frequent clogging, component wear, and unplanned stoppages, crippling your availability metrics.
High Operational Costs: Inefficient water usage, excessive fuel consumption for power, and large crew requirements for manual oversight drive your cost per ton unsustainably high.
Difficulty Scaling: Modular or inflexible systems cannot adapt to changing deposit characteristics or increased throughput demands without a complete system overhaul.

Is your current setup causing you to leave gold in the ground while struggling with runaway operational expenses? The solution lies in a purposeengineered 500 Tph Gold Mining Washing Plant designed not just for volume, but for maximum recovery and operational economy.

2. PRODUCT OVERVIEW

This is a complete, skidmounted or modular 500 TonPerHour Gold Mining Washing Plant engineered for highvolume alluvial and eluvial deposits. It is a continuous processing system designed to scrub, classify, concentrate, and recover gold from unconsolidated material.

Operational Workflow:
1. Primary Feed & Scrubbing: Runofmine material is fed via hopper and conveyor into a robust scrubbing section (trommel or scrubber) to break down clays and agglomerates.
2. Particle Classification: The liberated material is precisely screened and classified into multiple size fractions (e.g., oversize, midsize, fines) using vibrating screens or trommel decks.
3. Gravity Concentration: Each targeted size fraction is routed through optimized gravity circuits—such as primary sluices, jigs, or centrifugal concentrators—to recover free gold.
4. Tailings Management & Water Handling: Waste material is efficiently conveyed away while process water is recirculated through a settling pond or clarification system to minimize fresh water demand.

Application Scope & Limitations:
Scope: Ideal for largescale alluvial/placer gold projects, riverine deposits, and weathered eluvial zones with high clay content requiring aggressive scrubbing.
Limitations: Not suitable for hard rock (lode) mining without primary crushing. Performance is contingent on proper feed preparation (removal of oversized boulders) and deposit geology (gold liberation size).

6. APPLICATION SCENARIOS

LargeScale Alluvial Operation in West Africa

Challenge: A major operator faced falling recovery rates (<90%) and high water trucking costs due to an inefficient opencircuit washing plant processing highly variable clayrich gravels.
Solution: Implementation of our modular 500 Tph Gold Mining Washing Plant featuring the advanced scrubbing circuit and closedloop water management system.
Results: Achieved consistent recovery of >94%. Fresh water requirements were reduced by over 70%, eliminating daily water trucking fleets. Plant availability increased from 82% to over 91%.

Eluvial Deposit Development in South America

Challenge: Developing a mountainous eluvial deposit required a plant that could be transported in sections via winding roads and handle highly abrasive weathered ore without excessive liner wear.
Solution: A skidmounted version of the plant was supplied with heavyduty material handling specifications throughout.
Results: The plant was assembled onsite in under five weeks. Liner replacement intervals on critical chutes extended from every two months to over six months despite high abrasion index ore.
