1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

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. Les points douloureux courants incluent:

High Clay and Fines Content: Agglomeration and blinding of traditional scrubbers and screens, leading to significant gold loss in fines, débit réduit, and constant maintenance.
Inefficacité de l’eau et de l’électricité: Ineffective washing and screening loops consuming excessive water (souvent 500+ m³/h) and highpower motors, driving up operational expenses.
Temps d'arrêt fréquents pour la 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. APERÇU DU PRODUIT

The Industrial 500 L'usine de lavage de l'or TPH est une installation modulaire, heavyduty processing system engineered for the primary scrubbing, décomposition de l'argile, dépistage, and gravity preconcentration of goldbearing alluvial, éluvial, or weathered hard rock ore at a nominal 500 tonnes métriques par heure.

Flux de travail opérationnel:
1. Alimentation principale & Lavage: Runofmine (ROM) le matériau est introduit dans un épurateur à trommel robuste ou un épurateur rotatif, where intense attrition breaks down clay matrices and liberates gold particles.
2. Dimensionnement & Classification: Le matériau lavé est tamisé; surdimensionné (typically +75mm) is rejected as waste or sent for crushing. The undersize reports to further washing screens or vibrating decks for precise classification.
3. Concentration primaire: Matériau fin (10mm to 2mm) is routed to primary gravity concentrators (par ex., concentrateurs centrifuges, écluses) to recover liberated gold, significantly reducing the volume of material for downstream processing.

Champ d'application & Limites:
Portée: 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.
Limites: Not a substitute for chemical processing (par ex., CIP/CIL) pour minerais réfractaires. Ultimate recovery depends on adequate liberation in the scrubbing stage. Performance is contingent on consistent feed control and appropriate water supply.
