NOUFERROUS METALLURGICAL EQUIPMENT

The article provides a systematic summary of the key technologies used for the centerline embankment method, which has been appliedin the construction and operation of three tailings facilities: Tailings Pond No.4 and No.5 of Dexing Copper Mine, and Yulangpei TSF of Pulang Copper Mine. These technologies include both those that have been used during construction and operation as well. The key technologies used during construction include: site selection, tailings classification system selection and tailings balance calculation. The key technologies during operation include: real-time control of the tailings used for centerline embankment, phase-wise use of machinery for embankment, continuous embankment with the coarse secondary tailings, and the multi-dimensional flood containment and discharge system used in rainy areas. The improvement and development of these key technologies have important guiding implications for the construction and operation of tailings facilities of the same kind, and can contribute to the promotion and application of the centerline embankment method in China.
