1. PYNPUNT GEDREWE OPENING

Are you scaling up your alluvial or eluvial gold operation and facing the critical bottlenecks of highvolume material processing? 'n Standaard 500 TPH gold mining washing plant is a significant capital investment, yet many operations struggle with hidden costs that erode profitability. Algemene uitdagings sluit in:
High Downtime for Maintenance: Frequent clogging in scrubbers or screens halts the entire processing line, duisende per uur in verlore produksie kos.
Inkonsekwente herstelkoerse: Variable feed material can overwhelm traditional trommels and sluices, leading to fine gold loss that directly impacts revenue.
Excessive Water & Kragverbruik: Inefficient pump systems and plant design lead to unsustainable operational expenses, especially in remote sites.
Rapid Component Wear: Abrasive clays and gravel degrade standard liners and screens quickly, increasing part replacement frequency and labor costs.
Difficulty in Achieving SteadyState Operation: Balancing feed rate, scrubbing efficiency, and gold concentration across a 500 TPH system is complex, often resulting in suboptimal throughput.

How do you ensure your major equipment investment delivers not just capacity, but reliable, costeffective ounces? The solution lies in an engineered approach focused on durability, recovery optimization, en totale koste van eienaarskap.

2. PRODUK OORSIG

Hierdie 500 TPH mobile or modular gold mining washing plant is a complete gravity separation system designed for highvolume placer, alluvial, and eluvial deposits. It integrates robust scrubbing, precise classification, and efficient concentration into a continuous process flow.

Operasionele werkvloei:
1. Primary Feed & Scrubbing: Runofmine material is fed via hopper or conveyor into a heavyduty rotating scrubber, thoroughly breaking down clay agglomerates and liberating gold.
2. Material Classification: The discharged slurry is processed by a vibrating screen deck to separate oversize waste rock (+10mm to +75mm depending on deposit) from the valuable fines.
3. Fine Material Concentration: The undersize slurry containing gold reports to a series of enhanced gravity concentrators (such as centrifugal concentrators or pulsating sluices) for primary recovery.
4. Uitskotbestuur & Water Handling: Waste streams are directed to a settling system or dewatering unit for water reclamation, critical for environmental compliance and reducing fresh water intake.

Toepassingsomvang & Beperkings:
Ideaal vir: Largescale alluvial operations, riverine deposits, weathered eluvial zones with high clay content, and gravel pit reconcentration projects.
Beperkings: Not suitable for hard rock (lode) mining without prior crushing. Optimal performance requires adequate water supply (though recirculation systems minimize this). Feed material size typically limited to less than 250mm.
