1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

L'augmentation des coûts opérationnels et les temps d'arrêt imprévisibles érodent les marges de votre projet d'exploitation aurifère? Commercial operators consistently face critical challenges that directly impact profitability:

Dépenses opérationnelles élevées: Excessive fuel consumption, remplacement fréquent des composants, and high water usage in processing create unsustainable cost structures.
Temps d'arrêt imprévus: Equipment failure in remote locations leads to significant production halts, with repair logistics costing thousands per hour in lost recovery.
Faibles taux de récupération & Variabilité des notes: Inefficient separation results in valuable fine gold loss to tailings, while inflexible equipment struggles with changing ore body characteristics.
Intensité du travail & Pénuries de compétences: Reliance on complex, manuallyadjusted systems increases labor costs and introduces human error, a critical issue in regions with scarce skilled technicians.
Environnemental & Pression réglementaire: Inefficient water recycling and chemical use increase operational costs and regulatory compliance risks.

Is your operation equipped to lower your cost per ton, maximize recovery from complex ores, and ensure reliable uptime in demanding environments? The right equipment portfolio is a strategic investment, not just a capital purchase.

2. APERÇU DU PRODUIT: MODULAR GRAVITY CONCENTRATION & PROCESSING PLANTS

This product line encompasses modular, highcapacity gravity concentration systems designed for alluvial (placer) et du hard rock (filon) primary and secondary gold recovery. Engineered for the commercialscale operation, these plants optimize the physical separation of gold from gangue material based on specific gravity differentials.

Flux de travail opérationnel:
1. Préparation des aliments: Raw material is screened and classified to ensure optimal feed size for downstream concentration.
2. Concentration primaire: HighG force centrifugal concentrators continuously separate heavy minerals (or) from lighter materials.
3. Middlings & Manutention des résidus: Efficient slurry routing ensures maximum recovery while minimizing water consumption.
4. Concentrate Upgrading: The produced heavy mineral concentrate is easily discharged for further upgrading via shaking tables or selective batch concentrators.
5. Gestion de l'eau: Integrated water recirculation systems are standard, drastically reducing fresh water intake and settling pond requirements.

Champ d'application: Ideal for processing alluvial deposits, matériaux éluviaux, and milled hard rock ores where free gold is present. Serves as a primary recovery unit or a scavenger for ball mill/grinding circuit discharges.

Limites: Not a chemical leaching system. Recovery efficiency is inherently tied to the liberation size of the gold particles. For refractory ores where gold is locked within sulfide minerals, this system functions as a preconcentration stage ahead of leaching circuits.
