1. PAINPOINT DRIVEN OPENING

Are you facing escalating operational costs and unpredictable recovery rates in your highvolume gold mining operation? Managing a 500tonperhour feed presents distinct challenges that directly impact profitability. Common pain points include:

High Clay and Fines Content: Agglomeration and blinding of traditional scrubbers and screens, leading to significant gold loss in fines, reduced throughput, and constant maintenance.
Water and Power Inefficiency: Ineffective washing and screening loops consuming excessive water (often 500+ m³/hr) and highpower motors, driving up operational expenses.
Frequent Downtime for Maintenance: Abrasive feed materials causing rapid wear on components, resulting in unplanned shutdowns that cost tens of thousands per hour in lost production.
Inconsistent Feed Grade Handling: The inability of a static plant design to efficiently process variable ore hardness and clay content, forcing a compromise on either recovery or throughput.

Is your current setup struggling to maintain 500 TPH with high availability while ensuring optimal gold recovery from complex, alluvial or weathered deposits? The solution requires a purposebuilt washing plant designed for scale and resilience.

2. PRODUCT OVERVIEW

The Industrial 500 TPH Gold Mining Washing Plant is a modular, heavyduty processing system engineered for the primary scrubbing, clay breakdown, screening, and gravity preconcentration of goldbearing alluvial, eluvial, or weathered hard rock ore at a nominal 500 metric tons per hour.

Operational Workflow:
1. Primary Feed & Scrubbing: Runofmine (ROM) material is fed into a robust trommel scrubber or rotary scrubber, where intense attrition breaks down clay matrices and liberates gold particles.
2. Sizing & Classification: The scrubbed material is screened; oversize (typically +75mm) is rejected as waste or sent for crushing. The undersize reports to further washing screens or vibrating decks for precise classification.
3. Primary Concentration: Fine material (10mm to 2mm) is routed to primary gravity concentrators (e.g., centrifugal concentrators, sluices) to recover liberated gold, significantly reducing the volume of material for downstream processing.

Application Scope & Limitations:
Scope: Ideal for surface mining operations targeting freemilling gold in deposits with high clay content, sticky soils, or requiring aggressive attrition. Suited for both fixed plant installations and semimobile configurations.
Limitations: Not a substitute for chemical processing (e.g., CIP/CIL) for refractory ores. Ultimate recovery depends on adequate liberation in the scrubbing stage. Performance is contingent on consistent feed control and appropriate water supply.
