Tianjin Meiteng Puts Five XRT Ore Sorters Into Operation for Tajik-China Mining

Why It Matters

The deployment cuts processing costs and stabilises production for a key regional miner, while proving Meiteng’s ability to deliver large‑scale, high‑efficiency sorting solutions abroad.

Key Takeaways

• Five XRT sorters now run at Tajik-China Mining
• Waste rejection rate reached 14.83% during trials
• Tailings Pb+Zn grade held at ~0.4%, cutting processing costs
• Meiteng assumed operation and maintenance of all XRT units
• Central Asia spare-parts hub supports Kazakhstan and Russia deployments

Pulse Analysis

The harsh climate of Tajikistan’s Sughd province—ranging from –35 °C to +40 °C—has long hampered traditional beneficiation methods, forcing miners to grind low‑grade ore at high cost. Sensor‑based sorting emerged as a promising alternative, yet early 2023 trials faltered due to instability. Meiteng’s XRT technology, a dry‑separation system that combines X‑ray transmission with advanced AI, finally delivered consistent performance, allowing Tajik‑China Mining to reject nearly 15% of waste material while preserving valuable lead‑zinc content in the concentrate.

By taking over operation and maintenance, Meiteng not only ensured continuous uptime but also provided a turnkey service model that addresses the region’s logistical challenges. The 0.4% tailings grade indicates a significant reduction in downstream processing load, translating into lower energy consumption and reduced wear on grinding mills. For Tajik‑China Mining, which supplies roughly half of Tajikistan’s metal output, the efficiency gains improve profit margins and bolster its position as Asia’s largest lead producer.

Meiteng’s success in Tajikistan dovetails with its broader expansion strategy across Central Asia. The company has already installed XRT and TGS® sorters in Kazakhstan and Russia, and it has established a regional spare‑parts warehouse and technical team to support rapid service response. As the global mining sector pivots toward greener, smarter operations, dry‑separation technologies like XRT offer a lower‑water, lower‑energy alternative to conventional wet processes. Meiteng’s partnerships with Fortune Global 500 firms and its STAR Market listing underscore its growing influence, positioning it as a key supplier of “China solutions” to the international mining community.
