1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Managing a modern gold processing operation requires balancing throughput, taux de récupération, and stringent environmental responsibilities. Traditional comminution and concentration methods often fall short, creating significant operational hurdles. Êtes-vous confronté à ces défis?

Coûts opérationnels élevés & Temps d'arrêt: Conventional stamp mills and crushers are maintenanceintensive, with frequent liner changes and mechanical failures leading to unplanned stoppages. Each hour of downtime directly impacts your bottom line.
Libération d’or inefficace & Récupération: Older milling technology may not achieve optimal particle size, leaving valuable gold locked within host rock and reducing overall plant recovery rates.
Consommation excessive d'eau & Gestion des résidus: Waterintensive processes create large volumes of slurry tailings, escalating water sourcing costs and increasing the complexity and liability of tailings dam management.
Réglementaire & Pression communautaire: Bruit, poussière, and chemical runoff from traditional operations can lead to permitting delays, community opposition, and difficulty meeting modern environmental, social, and governance (ESG) normes.
Intensité énergétique: Inefficient grinding mechanisms consume excessive power per ton of ore processed, faire de l’énergie l’un de vos coûts variables les plus importants.

If these issues affect your profitability and operational license, an engineered ecofriendly stamp mill solution warrants serious consideration.

2. APERÇU DU PRODUIT

Notre EcoFriendly Modular Stamp Mill Plant is a reengineered gravity concentration system designed for primary and secondary crushing of goldbearing quartz ore. It integrates modern materials science and process control to deliver efficient gold liberation with a minimized environmental footprint.

Flux de travail opérationnel:
1. Alimentation contrôlée: Sized ore is conveyed into an integrated feed hopper with a regulated gate for consistent flow.
2. Impact Liberation: Heavyduty, tungstencarbidetipped stamps drop in a controlled sequence onto ore beds within sealed mortar boxes, fracturing rock along grain boundaries.
3. WaterEfficient Slurry Formation: A closedcircuit water system introduces minimal moisture to create a transportable slurry within the mill.
4. Integrated Concentration: Liberated heavy gold particles are immediately captured via integrated shaking tables or centrifugal concentrators within the same modular unit.
5. Dry Stack Tailings Option: Processed tailings can be directed toward a filter press system (facultatif), significantly reducing water content for safer, more stable drystack storage.

Champ d'application & Limites:
Idéal pour: Roche dure (filon) gold deposits, particularly freemilling ores; small to mediumscale operations (5200 DPT); regions with water scarcity or strict environmental regulations; sites seeking modular, movable plants.
Limites: Not suitable for highclay or deeply weathered oxide ores that cause packing; less effective for refractory ores requiring chemical treatment; maximum feed size is typically limited to 2 pouces.
