1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Gérez-vous des opérations de récupération d’or alourdies par un débit incohérent, consommation élevée de réactifs, and excessive downtime for liner changes? The limitations of conventional crushing and grinding circuits directly impact your bottom line. Considérez ces défis:
Recovery Inefficiency: Coarse gold can be lost in traditional ball mill circuits, leading to a measurable decrease in overall yield.
Coûts opérationnels élevés: Frequent maintenance cycles for complex grinding systems result in significant labor costs and production halts.
Problèmes d'évolutivité: Modular or remote operations struggle with the footprint and infrastructure demands of standard milling setups.
Process Complexity: Integrating effective gravity recovery within a continuous flow sheet often requires additional, costly equipment.

What if a proven, robust technology could consolidate crushing and primary grinding while enhancing gravity recoverable gold (GRG) capture at the head of your circuit?

2. APERÇU DU PRODUIT: Industrial Stamp Mill for Gold Ore Processing

An industrial stamp mill is a mechanical crusher designed for the coarse liberation of gold from hard rock ore. It utilizes heavy, verticallylifted stamps that are repeatedly dropped onto ore fed into a mortar box, fracturing material through direct impact. This method is particularly effective for freemilling ores where gold is unlocked at a coarse size.

Flux de travail opérationnel:
1. Présentation du flux: Minerai brut ou minerai concassé primaire (<50mm) is fed into the stamp mill’s mortar box.
2. Concassage par impact: Timbres levés mécaniquement (5001000+ kg chacun) chute dans une séquence contrôlée, pulvériser le minerai contre une matrice durcie.
3. Formation de boue & Décharge: De l'eau est introduite pour créer une bouillie, which flows over an amalgamation plate (if used) and is discharged for further classification or secondary processing.

Champ d'application & Limites:
Idéal pour: Minerais d'or en broyage libre, usines pilotes, opérations à petite et moyenne échelle (150 DPT), retraitement de sites historiques, and operations prioritizing robust, lowtech reliability with high GRG recovery.
Limites: Not suitable for refractory ores requiring fine grinding for chemical liberation. Higher energy per ton compared to some modern circuits for fine grinding. Requires consistent feed size control.
