1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are you managing gold processing operations where high capital expenditure, stringent environmental compliance, and unpredictable operating costs are eroding your project margins? The challenge of extracting maximum value from ore while controlling both upfront and longterm expenses is a constant pressure. Considérez ces obstacles opérationnels courants:
High Initial Investment & Long Payback Periods: Traditionnel, largescale milling circuits require significant capital, making them prohibitive for small to midtier deposits or exploratory phases.
Regulatory & Environmental Compliance Risks: Noncompliant equipment can lead to site shutdowns, amendes, and reputational damage, particularly concerning hazardous substances (RoHS, REACH).
Operational Inefficiency with Variable Ore Grades: Inflexible systems struggle to maintain optimal recovery rates when feed quality fluctuates, leaving profit in the tailings.
Temps d'arrêt excessif pour la maintenance: Complex assemblies with nonstandard parts lead to prolonged stoppages, directly costing you in lost production.
High Energy Consumption per Ton Processed: Inefficient crushing and grinding mechanics translate directly into unsustainable power costs.

Is there a solution that balances affordable entry cost with robust, compliant performance? One that offers simplicity without sacrificing recoveries?

2. APERÇU DU PRODUIT

The ROHS Compliant Stamp Mill represents a modern reinterpretation of a proven gravity concentration principle, engineered for today’s responsible and costconscious gold mining operations. This equipment is designed for primary crushing and grinding of goldbearing quartz rock and other ores, liberating gold for subsequent recovery via gravity methods like sluices or shaking tables.

Flux de travail opérationnel:
1. Alimentation: Ore is manually or mechanically fed into a sturdy feed hopper.
2. Écrasement & Affûtage: Camdriven stamps (heavy iron or steel shoes) are lifted and dropped onto the ore bed within a mortar box, repeatedly fracturing the material.
3. Pulvérisation & Laver: A continuous flow of water flushes the finely crushed slurry over an amalgamation plate (si configuré) and/or onto downstream concentration equipment.
4. Concentration: The goldrich slurry is channeled to gravity separation devices to capture freemilling gold.

Champ d'application & Limites:
Idéal pour: Smallscale mining operations, usines pilotes, processing highgrade vein material, artisanal and smallscale mining (ASM) formalization projects, and remote sites with limited infrastructure.
Limites: Not suitable for largescale, opérations à fort tonnage (>50 TPD typically). Efficiency decreases with complex ores requiring fine grinding below ~100 mesh or those with low freemilling gold content. It is a specialized tool within a processing circuit.
