1. PAINPOINT DRIVEN OPENING

Scaling your gold recovery operation to 500 TPH introduces significant logistical and operational complexities. Are you facing these critical challenges?

High Capex & Shipping Delays: Procuring and shipping a largescale plant often involves multiple vendors, complex customs, and extended lead times, delaying your project's revenue phase.
OnSite Assembly Complexity: Modular plants that require extensive welding, alignment, and commissioning onsite lead to prolonged downtime, labor overruns, and safety risks.
Inconsistent Feed Handling: At 500 TPH, variations in clay content, particle size distribution, or oversize material can rapidly choke conventional scrubbers and screens, causing systemic failure and costly stoppages.
Suboptimal Recovery in Coarse Fractions: Inefficient scrubbing and screening can leave gold locked in conglomerates or behind undersized trommel screens, directly impacting your overall recovery rate and profitability.
Operational Inflexibility: Fixedconfiguration plants struggle to adapt to changing ore body characteristics or seasonal water availability, locking you into a single processing mode.

The central question for plant managers is: how do you deploy a reliable, highcapacity washing plant that minimizes shipping risk, accelerates commissioning, and maximizes recovery from variable feed?

2. PRODUCT OVERVIEW

The Bulk 500 Tph Gold Mining Washing Plant is a preassembled, modular processing system designed for the primary scrubbing, screening, and gravity concentration of alluvial or eluvial goldbearing material. Engineered for rapid deployment and highvolume throughput.

Operational Workflow:
1. Feed & PreScreening: Runofmine material is fed via apron feeder onto a primary vibrating grizzly to remove extreme oversize (+200mm).
2. Intensive Scrubbing: Material reports to a heavyduty rotary scrubber for aggressive attritioning to break down clays and cemented conglomerates.
3. Precise Size Separation: Discharged slurry is processed by a highcapacity trommel screen with multiple deck sections (e.g., +75mm waste rock exit; 75mm+10mm intermediate fraction; 10mm fines).
4. Concentration & Dewatering: The critical 10mm fraction is routed to a series of sluices or jigs for gold recovery. Coarse fractions can be further scanned or stockpiled.
5. Tailings Management: Effluent water and fines are directed to a settling pond or optional cyclone/water clarification module for recycling.

Application Scope & Limitations:
Scope: Ideal for largescale alluvial/eluvial deposits with high clay content requiring intensive liberation. Suitable for both fixed plant installations and semimobile mining campaigns.
Limitations: Not designed for hard rock (lode) ore processing. Performance is contingent on feed characteristics like clay plasticity and rock abrasiveness. Requires consistent water supply or closedloop system integration.
