1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

étendre les opérations de récupération de l’or à 500 Tph présente des défis distincts qui ont un impact direct sur la rentabilité. Vitesses d'alimentation incohérentes, consommation d'eau élevée, and excessive downtime for maintenance can erode margins. Êtes-vous confronté à ces problèmes?
Goulots d’étranglement du débit: Can your washing and scrubbing plant maintain a consistent 500 Tph feed without becoming a processing bottleneck, leading to pileup and lost production time?
Coûts opérationnels élevés: Are you managing escalating costs from water procurement, recycling system complexity, and highenergy consumption in your material handling and separation processes?
Pertes de récupération: Is inefficient scrubbing or claybound material causing precious gold fines to be lost to tailings, directly reducing your overall yield?
Temps d'arrêt imprévus: Are frequent mechanical failures in scrubbers, écrans, or pumps causing unpredictable stoppages, making production targets unreliable?

Un robuste 500 Tph gold mining washing plant is engineered to address these exact operational challenges.

2. APERÇU DU PRODUIT

This product is a highcapacity, modular washing plant designed for alluvial and eluvial gold deposits. Its primary function is to liberate gold from claybound gravels and efficiently separate valuable material from waste through scrubbing, dépistage, and gravity concentration.

Flux de travail opérationnel:
1. Alimentation principale & Lavage: Runofmine (ROM) material is fed into a heavyduty trommel or scrubber, where intense agitation breaks down clays and cemented aggregates.
2. Dimensionnement & Classification: The disaggregated material passes over vibrating screens, separating +2mm to +10mm (spécifique au site) surdimensionné (stériles) from the valuable undersize fraction.
3. Concentration & Récupération: The undersize slurry is routed to primary gravity concentrators (par ex., écluses, gabarits) for initial gold recovery. Tailings may pass through secondary scavenging units.
4. Gestion de l'eau & Résidus: Process water is clarified in a settling system for recirculation, minimizing fresh water intake. Waste streams are managed for responsible disposal.

Champ d'application & Limites:
Portée: Ideal for largescale alluvial/eluvial operations, placer deposits, and weathered conglomerates where clay removal is essential prior to cyanidation or further processing.
Limites: Not suitable for hard rock lode deposits without prior crushing. Performance is highly dependent on feed material characteristics (teneur en argile, plasticity, rock size).
