NOUFERROUS METALLURGICAL EQUIPMENT

This study proposes a novel graded dehydration filling process for total tailings. The process involves the classification of total tailings into coarse and fine fractions, with the coarse fraction undergoing natural gravity sedimentation for dehydration and the fine fraction undergoing flocculated gravity sedimentation. To implement this process, specialized graded dehydration equipment has been developed. Compared to traditional total tailings dehydration methods, this graded dehydration process significantly enhances concentration efficiency, reduces energy consumption and dehydration costs, and minimizes environmental pollution. The process exhibits broad applicability, particularly for total tailings filling projects in non-coal metal mines, offering a new technical pathway for the sustainable development of mine filling technology.
