1. PAINPOINT DRIVEN OPENING

Are you managing a highvolume gold operation where consistent throughput and recovery rates are compromised by inefficient material scrubbing and classification? Operational bottlenecks at 500 TPH can translate to significant revenue loss. Consider these common challenges:
Inconsistent Feed & ClayBearing Material: Variable ore with high clay content can blind screens, reduce scrubbing efficiency, and lead to gold losses in the undersize fraction.
High Water & Power Consumption: Traditional washing plants often operate with fixed flow rates and nonoptimized pump systems, leading to unsustainable utility costs.
Excessive Downtime for Maintenance: Poorly designed trommels and scrubbers with inadequate wear protection require frequent liner changes and component repair, halting your primary production line.
Difficulty Meeting Environmental Compliance: Managing water recycling and tailings from a highcapacity plant is complex; inefficient solids removal overloads settling ponds and filtration systems.

How do you ensure your 500 TPH operation maximizes gold recovery while controlling operational expenditure and maintaining continuous runtime? The solution requires a purposeengineered washing plant designed for industrialscale efficiency.

2. PRODUCT OVERVIEW

The CE Marked 500 TPH Gold Mining Washing Plant is a complete, modular processing system engineered for the primary scrubbing, clay breakdown, size classification, and material preparation of alluvial or hard rock gold ores. It serves as the critical frontend to your recovery circuit, ensuring optimal feed material for downstream concentration units like centrifugal concentrators or sluice arrays.

Operational Workflow:
1. Feed & Primary Scrubbing: Runofmine ore is introduced into a robust trommel scrubber, where lifters aggressively break down clay conglomerates and soft oxides.
2. Size Classification: The rotating trommel screen separates material into two key streams: oversize (gravels/rocks) and undersize (sand, silt, and goldbearing fines).
3. Material Handling: Oversize material is conveyed to waste stockpile. The undersize slurry is efficiently distributed to subsequent recovery modules.
4. Optional Secondary Screening: A vibrating screen deck can further classify undersize material to optimize feed grade for specific recovery technologies.
5. Water Management: Effluent is channeled to a integrated settling/sump system for water recycling, minimizing fresh water requirements.

Application Scope & Limitations:
Scope: Ideal for alluvial/eluvial deposits, weathered saprolite zones, and placer operations requiring highvolume clay removal. Effective as a preconcentration plant for hard rock operations where ore requires liberation.
Limitations: Not a standalone recovery solution; requires downstream gold capture units. Performance is dependent on accurate feed characterization (clay content, moisture, rock size distribution).
