Eco-Friendly Stamp Mill Gold Mining Brochure
1. PAINPOINT driven اوپننگ
سون جي پروسيسنگ آپريشن کي منظم ڪرڻ جي ضرورت آهي توازن جي ذريعي, بحالي, ۽ آپريشنل خرچ. Traditional comminution methods often fall short, creating significant bottlenecks. ڇا توهان انهن مسلسل چئلينج کي منهن ڏئي رهيا آهيو?
اعلي توانائي واپرائڻ & لاڳت: 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 & ٽائلنگ جو انتظام: Wet milling processes demand large volumes of water and create slurry tailings that are costly to contain and remediate.
Operational Downtime for Maintenance: بار بار لائنر تبديليون, برداشت جي ناڪامي, 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. پيداوار جو جائزو: 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.
آپريشنل ڪم فلو:
1. کاڌ خوراڪ جي تياري: رنوفمين يا پرائمري پسيل معدنيات (<50ايم ايم) is fed into a sealed hopper.
2. GravityImpact Milling: Camdriven heavyduty stamps (هٿيار) repeatedly drop onto the ore bed contained within a hardened steel mortar box, pulverizing material through controlled impact.
3. درجه بندي & ريسائيڪلنگ: 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.
ايپليڪيشن جو دائرو & حدون:
لاء مثالي: ننڍي کان وچولي پيماني تي آپريشن (150 ٽي پي ڊي), vein mining, پائلٽ ٻوٽا, remote sites with limited water access, and regions with strict environmental regulations prohibiting mercury or cyanide.
Best Suited Ore Types: Freemilling gold in quartz, سلفيڊ سان لاڳاپيل معدنيات (postroasting), and other brittle materials.
حدون: Not optimal for highclay content ores (causes packing), very hightonnage operations (>100 ٽي پي ڊي), or where ultrafine grinding (<100 ميش) is required as a standalone solution.

6. درخواست جا منظر
هنرمند & ننڍي اسڪيل کان کني (اي ايس ايم) Formalization Project – West Africa
چيلنج: 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.
نتيجا: 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
چيلنج: 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.
نتيجا: 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.
