Theoretical research and technical support can be provided for various mine enterprises forproducing tailings, such as colored, black, noble metals, rare metals, gold and the like.

Description

technical field [0001] The invention relates to the technical field of paste filling tailings thickening, in particular to a rheometer-based tailings dehydration performance detection device and a use method. Background technique [0002] Paste filling mining technology is the most cutting-edge filling mining technology at present. It has the advantages of environmental protection, economy, safety and high efficiency. It is one of the hot research technologies in the field of mining at home and abroad in recent years. After years of research and practice, this technology has been successfully applied to many metal mines in my country. [0003] Tailings thickening is an important process of paste filling. Generally, the tailings of the dressing plant are directly pumped into the deep cone thickener for a stage of dehydration. During the entire dehydration process, the most critical is the dehydration concentration and the internal rake torque of the thickener. Because the t...
