Kinë 500 Fabrika e larjes së minierave të arit TPH: HighCapacity Alluvial Gold Recovery Solution
Operational Challenges in LargeScale Gold Recovery
Your operation faces three persistent bottlenecks: declining recovery rates below 85% due to claybound feed material, tejkalimi i kohës joproduktive të paplanifikuar 120 hours annually from screen blinding and pump failures, and escalating water consumption above 4,000 m³ per day for 500 Rrjedha e TPH. Each percentage point lost in recovery represents approximately $15,000–$25,000 in unrecovered gold value per month at current market prices. Equipment wear from abrasive quartz and lateritic clays forces complete liner replacements every 800–1,200 operating hours, adding $180,000–$250,000 in annual maintenance costs.
Can your current washing plant handle feed moisture content exceeding 18% without sacrificing throughput? Are you losing fine gold particles below 75 microns to overflow discharge? Does your existing setup require twostage crushing before washing, adding $0.40–$0.60 per ton in preprocessing costs?
Pasqyrë e produktit: Integrated Washing and Recovery System
The China 500 TPH Gold Mining Washing Fabrika është një modular, skidmounted system combining rotary trommel scrubbing, highpressure spray washing, and multistage gravity concentration. Designed for alluvial, eluvial, and weathered hardrock deposits, this plant processes runofmine feed with clay content up to 40% and particle sizes up to 600 mm.
Rrjedha e punës operative:
1. Përgatitja e ushqimit: Runofmine material enters a vibrating grizzly feeder (bar spacing 50–80 mm) të skalpit të tepërt >150 mm, which discharges to a reject conveyor.
2. Trommel Scrubbing: Feed enters a 2.4 m diameter × 8.0 m long rotary trommel with internal lifters and highpressure spray bars (12–16 bar, 8 grykë për metër linear). Retention time adjustable 45–90 seconds via variable frequency drive (VFD).
3. Screening and Classification: Trommel screen sections (two decks: 10 mm and 2 hapje mm) separate +10 mm oversize (refuzoj), 2–10 mm middlings (secondary crushing optional), dhe 2 mm llum.
4. Përqendrimi i gravitetit: 2 mm slurry feeds a bank of 8–12 centrifugal concentrators (30 TPH secili) with automatic discharge cycles. Concentrate undergoes final upgrading via shaking tables or mercuryfree intensive cyanidation.
5. Menaxhimi i Ujit: Closedloop system with thickener (20 m diametër) and filter press recovers 85–90% of process water. Makeup water requirement: 400–600 m³/day.
Fusha e Aplikimit: Alluvial gold deposits, minierat e shtratit të lumit, old tailings reprocessing, weathered gold ores. Kufizimet: Not suitable for primary hardrock ores requiring crushing below 10 mm; maximum feed clay content 45% pa kushte paraprake.

FAQ
P: Can this plant handle feed with clay content exceeding 45%?
A: The standard configuration is optimized for up to 45% balta. For higher clay content (deri në 60%), we recommend adding a preconditioning drum or increasing trommel retention time via VFD adjustment. Field data shows recovery rates decline by 3–5% for each 5% increase in clay above 45%. A sitespecific test is recommended before ordering.
P: What is the expected gold recovery rate for fine particles (50–75 microns)?
A: For the 50–75 micron fraction, recovery typically ranges from 65–78% depending on gold morphology and clay content. Our centrifugal concentrators achieve 72–78% recovery for liberated gold in this size range. For particles below 50 mikronë, recovery drops to 40–55%; we recommend adding a flotation or intensive cyanidation circuit for optimal recovery.
P: How long does installation and commissioning take?
A: Përgatitja e vendit (themelet e betonit, furnizimi me ujë) requires 10–14 days. Equipment assembly and wiring: 7–10 days with a 4person crew. Commissioning and operator training: 3–5 days. Total timeline from delivery to full production: 20–28 days. We provide one commissioning engineer onsite for 10 ditë.
P: What is the power requirement and can it run on generator power?
A: Total installed power is 380 kW. Në 80% faktori i ngarkesës, actual consumption is 300–310 kW. For generator operation, we recommend a 500 kVA diesel generator (minimale 450 kVA). The VFD system includes softstart capability, reducing peak demand by 35%. Fuel consumption at full load: approximately 85–95 liters/hour.
P: What warranty and aftersales support do you offer?
A: Garancia standarde: 24 muaj ose 8,000 orët e punës (cilado që të vijë e para) for manufacturing defects. Vishni pjesë (astar, ekranet, spray nozzles) janë të përjashtuar. Aftersales support includes 24/7 diagnostifikimi në distancë, a regional parts warehouse (stocking 200+ critical components), and guaranteed 48hour dispatch for emergency parts.
P: Can this plant be expanded to 750 TPH in the future?
A: po. The modular design allows capacity expansion by adding a second trommel module in parallel or upgrading to a 2.8 m diameter trommel. Estimated cost for 750 TPH upgrade: $320,000–$420,000. The existing thickener and filter press can handle up to 650 TPH; above that, additional water treatment capacity is required.
P: Cilat janë kërkesat e pajtueshmërisë mjedisore?
A: The closedloop water system meets most international standards (IFC, World Bank) for zero liquid discharge. Sterilet (tepër i madh +10 mm) are drystacked; 2 mm tailings from concentrators are thickened to 55–65% solids for dry stacking or pond disposal. Noise levels meet OSHA requirements with standard enclosures. We provide environmental compliance documentation for permitting.
