Xi'an University of Architecture and Technology recently announced a significant breakthrough led by Professor Bu Xianzhong from the School of Resource Engineering. The research team successfully addressed complex development obstacles at Mongolia's Long lake Bayan Iron Mine through advanced technological enhancements. Previously burdened by processing difficulties due to its ore composition, the Long lake Bayan Iron Mine struggled with low concentrate yield and subpar total iron recovery rates. Professor Bu Xianzhong's team conducted an on-site assessment last May, gathering ore samples for detailed analysis in China. Leveraging mineralogical experiments, they devised an innovative process of "ultrafine grinding+high gradient magnetic separation," achieving a notable concentrate grade of 54% total iron.

The project, from the submission of construction drawings to implementation, took just over 5 months, showcasing the team's technical expertise and efficient collaboration between China and Mongolia.

Ding Xiaoshu, the chief engineer, highlighted the economic benefits post-renovation, with over 150,000 tons of iron concentrate powder added annually. The mine director Сандаг praised the team's technical roadmap, anticipating an annual income increase of 22.5 billion Tugrik and a reduction of 200,000 cubic meters in tailings storage.

This successful project not only brought substantial gains to enterprises but also showcased Xi'an University of Architecture and Technology's technological edge in the mining sector, offering a replicable "China's plan" for countries along the Belt and Road Initiative. The partnership with Mongolia University of Science and Technology further strengthens mining technology cooperation along the Belt and Road, fostering closer ties between China and Mongolia.
