Upanuzi wa Kiwanda cha Kukunja Dhahabu cha Milioni 2 t/a katika Xinjiang, Uchina

Uboreshaji wa Kupondaponda na Kichujio:

• Integration of a new kiberiti kikuu cha kuzunguka to handle increased throughput.
• Existing two-stage crushing circuit (Jaw + Cone Crusher) optimized and retrofitted to form a robust mfumo wa kusagia hatua tatu, kuhakikisha ukubwa wa nishati wa 12mm chini kwa ajili ya kusaga.

Mzunguko Ulioboreshwa wa Kuongezea Uzito:

• Installation of new, high-efficiency 200 m³ seli za flotasheni 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 mfumo wa kupima viambato moja kwa moja to optimize collector and depressant usage, particularly for controlling arsenic.

Udhibiti wa Mchakato na Ukarabati

• DCentralized Mfumo wa udhibiti wa PLC/DCS integrated with the existing plant control room.
• Addition of vifaa vya mtandaoni vya kuchambua ukubwa wa chembe (PSD) and vifaa vya pH/ORP for real-time process optimization, ensuring stable operation at the expanded capacity.

Upanuzi wa Mzunguko wa Kusaga:

• Addition of a second Φ5.0m x 8.5m Kinu cha Mpira operating in parallel with the existing unit.
• Formation of a closed-circuit grinding system with hidrokiloni to achieve a target grind size of 80% passing 75µm, essential for liberating fine gold locked in sulfides.

Kuzingatia & Ushughulikiaji wa Taka:

• New thickener yenye kiwango cha juu for flotation concentrate dewatering.
• Installation of a filter press in Kiswahili is "kipresha chujio." for the concentrate to produce a low-moisture filter cake, reducing transportation costs.
• Imesasishwa mfumo wa kupumpa taka na bomba kwa ajili ya kituo cha kuhifadhi taka kilichopo, iliyoundwa kushughulikia kiwango kilichoongezeka.

Mukaanzo wa Maina na Matokeo ya Kupanua:

• Kiwango cha Uwezo: Successfully increased processing capacity by 800,000 t/a, kufikia lengo la tani milioni 2 kwa mwaka.
• Kuimarisha Uponyaji: Through finer grinding and optimized flotation, the overall gold recovery rate was significantly enhanced by 6.5%.
• Uwezo wa EPC ulio thibitishwa: Demonstrated strong capability in brownfield project execution, seamlessly integrating new systems with existing infrastructure with minimal disruption to ongoing production.
• Iliyotungidzwa kwa Madini Ya Kukaidi: The flowsheet is specifically designed to tackle the challenges of refractory sulfide gold ores prevalent in the region.
• Mkazo kwenye Ufanisi wa Ikolojia: The expansion prioritized water recycling from the thickener overflow and dry tailing stacking where applicable, aligning with stringent environmental policies in Xinjiang.
