1. ABERTURA ACIONADA POR PAINPOINT

Gerenciar uma operação de processamento de ouro requer equilíbrio no rendimento, recuperação, e custos operacionais. Traditional comminution methods often fall short, creating significant bottlenecks. Você está enfrentando esses desafios persistentes?

Alto consumo de energia & Custo: Conventional ball mills and crushers are energyintensive, with power costs consuming a disproportionate share of your operating budget.
Mercury Amalgamation Dependency: Inefficient liberation of gold from ore drives reliance on hazardous mercury amalgamation in the concentration stage, posing severe environmental and health liabilities.
Excessive Water Usage & Gestão de Rejeitos: Wet milling processes demand large volumes of water and create slurry tailings that are costly to contain and remediate.
Operational Downtime for Maintenance: Mudanças freqüentes de revestimento, falhas de rolamento, and unplanned stops in continuous systems directly impact tonnage processed and profitability.
Low Recovery Rates from Complex Ores: Inadequate particle size reduction fails to fully liberate fine gold particles locked within host rock, leaving revenue in the tailings.

What if your crushing and grinding circuit could address these issues simultaneously, reducing both operational expense and environmental footprint?

2. VISÃO GERAL DO PRODUTO: ECOFRIENDLY MODULAR STAMP MILL

The EcoFriendly Modular Stamp Mill is a modern reinterpretation of the classic gravityimpact crushing principle, engineered for selective milling of goldbearing quartz veins and hard rock ores. It is designed as a drycrushing or minimalwater addition system to facilitate mercuryfree gold recovery.

Fluxo de Trabalho Operacional:
1. Preparação de alimentação: Minério bruto ou britado primário (<50milímetros) is fed into a sealed hopper.
2. GravityImpact Milling: Camdriven heavyduty stamps (martelos) repeatedly drop onto the ore bed contained within a hardened steel mortar box, pulverizing material through controlled impact.
3. Classificação & Reciclagem: Crushed material passes through a replaceable screen grate at the mortar box exit. Oversize material is recycled; correctly sized material discharges for concentration.
4. Dry Processing Pathway: The milled, dry product is conveyed directly to downstream electrostatic, airgravity, or dry magnetic separators.

Escopo de aplicação & Limitações:
Ideal para: Small to midscale operations (150 TPD), vein mining, plantas piloto, remote sites with limited water access, and regions with strict environmental regulations prohibiting mercury or cyanide.
Best Suited Ore Types: Freemilling gold in quartz, minérios associados ao sulfureto (postroasting), and other brittle materials.
Limitações: Not optimal for highclay content ores (causa embalagem), very hightonnage operations (>100 TPD), or where ultrafine grinding (<100 malha) is required as a standalone solution.
