İşleme Yöntemi

  • Integration of a new birincil konik kırıcı to handle increased throughput.
  • Existing two-stage crushing circuit (Jaw + Cone Crusher) optimized and retrofitted to form a robust üç aşamalı kırma sistemi, öğütme için 12 mm altı tutarlı besleme boyutu sağlamak.
  • Installation of new, high-efficiency 200 m³ flotasyon hücreleri to form an expanded circuit.
  • Implementation of a “1-stage Rougher, 3-stage Cleaner, 2-stage Scavenger” configuration for superior selectivity and recovery.
  • Introduction of an advanced otomatik reaktif dozajlama sistemi to optimize collector and depressant usage, particularly for controlling arsenic.
  • DCentralized PLC/DCS kontrol sistemi integrated with the existing plant control room.
  • Addition of çevrimiçi parçacık boyutu analiz cihazları (PSD) and pH/ORP sensörleri for real-time process optimization, ensuring stable operation at the expanded capacity.
  • Addition of a second Φ5.0m x 8.5m Taneli Değirmen operating in parallel with the existing unit.
  • Formation of a closed-circuit grinding system with hidrosiklonlar to achieve a target grind size of 80% passing 75µm, essential for liberating fine gold locked in sulfides.
  • New yüksek oranda kalınlaştırıcı for flotation concentrate dewatering.
  • Installation of a filtre pressi for the concentrate to produce a low-moisture filter cake, reducing transportation costs.
  • Mevcut atık depolama tesisine, artan hacmi işlemek üzere tasarlanmış, geliştirilmiş atık pompalama sistemi ve boru hattı.
  • Kapasite Atılımı: Successfully increased processing capacity by 800.000 t/yıl2 milyon ton/yıl hedefine ulaşmak.
  • Kurtarma Artışı: Through finer grinding and optimized flotation, the overall gold recovery rate was significantly enhanced by 6.5%.
  • Kanıtlanmış EPC Yetenekleri: Demonstrated strong capability in brownfield project execution, seamlessly integrating new systems with existing infrastructure with minimal disruption to ongoing production.
  • Refrakter Cevhere Uygun Hale Getirilmiş: The flowsheet is specifically designed to tackle the challenges of refractory sulfide gold ores prevalent in the region.
  • Ekolojik Verimlilik Üzerine Vurgu: The expansion prioritized water recycling from the thickener overflow and dry tailing stacking where applicable, aligning with stringent environmental policies in Xinjiang.
