1. PAINPOINT DRIVEN OPENING

Scaling gold recovery operations to 500 Tph presents distinct engineering and financial challenges. Inefficiencies at this volume magnify losses and erode profit margins. Are you facing these operational hurdles?

Throughput Bottlenecks: Can your existing washing and scrubbing plant maintain consistent 500 Tph feed without frequent blockages or process overloading, leading to unscheduled downtime and lost production?
Inconsistent Recovery Rates: Are you experiencing gold losses in fines or to tailings due to inadequate scrubbing, poor clay/soft ore breakdown, or insufficient retention time in your trommel or scrubber section?
Excessive Operating Costs: Are your water consumption, power draw per ton processed, and wear part replacement costs becoming prohibitive at a 500 Tph scale, directly impacting your cost per ounce?
High Maintenance Demands: Does your plant require constant mechanical attention, with failures in bearings, drives, or screen sections causing costly operational delays?
Site Deployment Complexity: Is the installation and commissioning of a highcapacity plant causing significant project delays, with concerns over foundation requirements and modular integration?

A robust 500 Tph gold mining washing plant is engineered specifically to resolve these scalerelated issues.

2. PRODUCT OVERVIEW

A 500 Tph gold mining washing plant is a heavyduty, integrated processing system designed for alluvial or eluvial gold deposits. Its primary function is to break down cemented clays, scrub gravels, and liberate gold particles for subsequent concentration via sluices, jigs, or centrifugal concentrators.

Operational Workflow:
1. Primary Feed & Scalping: Runofmine (ROM) material is fed via apron feeder or conveyor into a robust scalping screen to remove oversized rocks (+75mm/100mm).
2. Intensive Scrubbing & Washing: The subscalped material enters a largediameter rotary scrubber or log washer. Highimpact paddles or lifters provide attrition to break down clays and soft conglomerates.
3. Particle Size Separation: The scrubbed slurry discharges onto a vibrating screen or trommel screen deck(s), typically with highpressure water spray bars. Target fractions (e.g., 10mm to +2mm) are separated for gold recovery.
4. Gold Concentration: The screened ore fraction containing liberated gold reports to the chosen recovery system (e.g., sluice banks, jig plants).
5. Waste Handling & Water Management: Oversize waste rock is conveyed to stockpile. Fines slurry is managed via sumps and pumps; water can be recirculated from settling ponds.

Application Scope & Limitations:
Scope: Ideal for largescale alluvial/eluvial projects, riverine deposits, and weathered conglomerates where claybound gold is present. Suited for greenfield installations or major upgrades.
Limitations: Not designed for hard rock (lode) ore processing. Performance is highly dependent on feed material consistency (clay content, moisture, rock size distribution). Requires significant water supply and settlement area.
