1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

étendre les opérations de récupération de l’or à 500 Tph présente des défis techniques et financiers distincts. Les directeurs d'usine et les entrepreneurs en ingénierie sont souvent confrontés:
Goulots d’étranglement du débit: Inefficient scrubbing and screening can cap processing capacity below 500 Tph, leaving valuable material unprocessed and limiting ROI on your deposit.
Hautes eaux & Consommation d'énergie: Traditional washing plants can require excessive water recirculation and highhorsepower drives, directly escalating operational costs and environmental footprint.
ClayBearing Material Handling: Sticky clays and agglomerates can blind screens, reduce classification efficiency, and cause significant downtime for manual cleaning.
Taux de récupération incohérents: Variable feed material can lead to gold losses in fines or to inadequate liberation of gold from gangue, impacting overall plant yield.
Usure rapide & Coûts d'entretien: The abrasive nature of alluvial or hard rock feed can lead to premature failure of critical components, resulting in unplanned stoppages and high parts replacement costs.

Is your operation achieving maximum payable gold recovery at a true 500tonperhour rate? Are you managing water and energy costs effectively while minimizing maintenance downtime?

2. APERÇU DU PRODUIT

UN 500 Tph Gold Mining Washing Plant is a highcapacity, système de traitement modulaire conçu pour le lavage primaire, dépistage, et concentration gravitaire des dépôts alluviaux ou éluviaux, or the preconcentration of hard rock mill feed. Its core function is to liberate gold particles from waste material (gang) and efficiently separate them by size and specific gravity.

Flux de travail opérationnel:
1. Alimentation & Lavage primaire: Runofmine (ROM) material is fed into a robust scrubber (trommel or rotary) where intense agitation breaks down clays, dissolves cemented aggregates, and liberates gold.
2. Dimensionnement & Classification: The scrubbed ore passes over vibrating screens or within the trommel itself to separate material into distinct size fractions (par ex., +10mm oversize waste, 10mm+2mm gravels, 2mm sands).
3. Concentration gravitationnelle: The goldbearing sand fraction is routed to a series of highcapacity gravity concentrators (tels que des concentrateurs centrifuges ou des écluses) to recover free gold particles.
4. Gestion des résidus & Recyclage de l'eau: Waste streams are conveyed away, while process water is sent to a settling system for clarification and recirculation.

Champ d'application & Limites:
This plant is engineered for largescale placer operations, alluvial projects, or as a primary wash plant for certain weathered deposits. Its effectiveness is highest on freemilling gold where liberation occurs through physical scrubbing. It is not a substitute for chemical leaching (CIL/CIP) plants required for refractory ores.
