1. فتحة مدفوعة بنقطة الألم

تتطلب إدارة عملية معالجة الذهب موازنة الإنتاجية, استعادة, والتكاليف التشغيلية. Traditional comminution methods often fall short, creating significant bottlenecks. هل تواجه هذه التحديات المستمرة?

استهلاك عالي للطاقة & يكلف: 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 & إدارة المخلفات: Wet milling processes demand large volumes of water and create slurry tailings that are costly to contain and remediate.
Operational Downtime for Maintenance: تغييرات متكررة في الخطوط الملاحية المنتظمة, تحمل الفشل, 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. نظرة عامة على المنتج: 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.

سير العمل التشغيلي:
1. تحضير الأعلاف: تشغيل منجم أو خام سحق الأولية (<50مم) is fed into a sealed hopper.
2. GravityImpact Milling: Camdriven heavyduty stamps (المطارق) repeatedly drop onto the ore bed contained within a hardened steel mortar box, pulverizing material through controlled impact.
3. تصنيف & إعادة التدوير: 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.

نطاق التطبيق & القيود:
مثالية ل: العمليات الصغيرة والمتوسطة الحجم (150 TPD), vein mining, النباتات التجريبية, المواقع النائية ذات الوصول المحدود للمياه, and regions with strict environmental regulations prohibiting mercury or cyanide.
Best Suited Ore Types: Freemilling gold in quartz, الخامات المرتبطة بالكبريتيد (postroasting), and other brittle materials.
القيود: Not optimal for highclay content ores (يسبب التعبئة), very hightonnage operations (>100 TPD), or where ultrafine grinding (<100 شبكة) is required as a standalone solution.

6. سيناريوهات التطبيق

الحرفي & التعدين على نطاق صغير (أسم) Formalization Project – West Africa

تحدي: A governmentsponsored project needed to replace hundreds of manual mortarandpestle and mercurydependent grinding sites with a scalable, cleaner technology that maintained simplicity but drastically reduced toxic emissions.
حل: Deployment of semimobile EFM5 stamp mill units at centralized processing hubs. Each unit served multiple mining cooperatives.
نتائج: Field data shows an average gold recovery increase of 22% due to improved liberation. Mercury use was eliminated at equipped hubs within six months.

Remote Hard Rock Exploration Camp – Canadian Shield

تحدي: An exploration company required onsite bulk sampling and pilot processing but had no access to water or grid power at the drill site. Transporting wet samples was prohibitively expensive.
حل: Installation of one EFM10 stamp mill powered by a hybrid solardiesel generator system coupled to a dry shaking table.
نتائج: The system processed over 500 tons of drill core reject material onsite, providing critical metallurgical data without water infrastructure. Power fuel costs were reduced by an estimated $15,000 during the campaign versus running a dieselpowered wet mill.
