en.Wedoany.com Reported - In late May 2026, the Qinghai Provincial Department of Science and Technology announced the results of the second batch of newly initiated science and technology projects for 2026. Two projects submitted by units under the Qinghai Provincial Bureau of Geology and Mineral Exploration and Development were both selected, receiving approval as special projects under the Qinghai Provincial Key R&D and Transformation Plan. The selected projects are the "Research and Application of Intelligent Sorting and Efficient Mineralization to Improve Beneficiation Indicators of Low-Grade, Fine-Grained, Disseminated Arsenic-Bearing Gold Ores," submitted by the Sixth Geological Exploration Institute of Qinghai Province (Dulan Jinhui Mining Co., Ltd.), and the "Research on the Application of a Data- and Physics-Driven AI Prospecting Prediction Large Model in the Qaidam Basin and Its Periphery," submitted by the Third Geological Exploration Institute of Qinghai Province. The simultaneous approval of both projects marks a new breakthrough for the Qinghai Provincial Bureau of Geology and Mineral Resources in the fields of green mineral processing and intelligent prospecting.

The Sixth Geological Exploration Institute of Qinghai Province and Dulan Jinhui Mining Co., Ltd. operate under an "integrated institute-enterprise" model. Founded in 2006, Dulan Jinhui Mining Co., Ltd. is a state-owned gold mining enterprise established by the Qinghai Provincial Bureau of Geology and Mineral Resources to promote the "Wulonggou Model," which emphasizes "exploration serving development, and development feeding back exploration." It integrates exploration, mining, beneficiation, and comprehensive tailings utilization, and is the largest gold mining enterprise in Qinghai Province in terms of daily processing capacity. The ore type in the Wulonggou area, where the company is located, is fine-grained altered rock-type gold ore prone to argillization, with extremely fine gold dissemination, making it a typical refractory gold ore.

Led by Dulan Jinhui Mining Co., Ltd., in collaboration with the University of Science and Technology Beijing and Liaoning Longji Optoelectronics Technology Co., Ltd., the mineral processing project aims to overcome bottlenecks in the development and utilization of structurally altered, arsenic-bearing refractory gold ores on the Qinghai-Tibet Plateau. In the preliminary phase, the Sixth Geological Exploration Institute of Qinghai Province completed industrial trials in the Wulonggou area: using intelligent sorting equipment for ore sections such as Huanglonggou, Hongqigou, and Heishigou, a stable waste rejection rate of 20.85% to 32.82% was achieved, with concentrate enrichment ratios ranging from 1.21 to 1.72, and the feed ore grade effectively increased by 0.29 to 0.36 grams per ton. Building on this, the project will focus on low-grade gold ores and waste rock from four ore sections, aiming to break through core technologies in intelligent sorting and efficient mineralization to recover gold resources from waste rock and achieve efficient utilization of low-grade ores.

The AI prospecting project, jointly submitted by the Third Geological Exploration Institute of Qinghai Province and Hunan University of Science and Technology, focuses on pain points in mineral resource exploration in the Qaidam Basin and its periphery, such as "difficulty in detection, identification, and prediction." It deeply integrates geophysical data with artificial intelligence technology, aiming to establish a scalable technical system for intelligent prospecting prediction and target area optimization. The Third Geological Exploration Institute of Qinghai Province possesses strong capabilities in geophysical exploration technology and has established a provincial database of gravity, geomagnetic, and aeromagnetic survey data. The project's outcomes have good reproducibility and broad applicability, with the potential for large-scale application in major metallogenic belts on the Qinghai-Tibet Plateau and other metallogenic areas, providing intelligent technical support for mineral resource exploration.

The approval and implementation of these two projects will drive technological progress in green mineral processing and intelligent prospecting in Qinghai Province, providing scientific and technological support for the transformation and upgrading of the geological exploration industry.
