Fine-grained tailing grading and zoning high-concentration upstream type damming process and method based on property improvement
The invention belongs to the technical field of ground surface stockpiling of fine-grained tailings, and particularly relates to a fine-grained tailing grading and zoning high-concentration upstream type damming process and method based on property improvement. The damming process comprises a dressing plant, a full-tailing pulp pipeline, a slurry pump and a hydraulic cyclone classifier. Aiming at the characteristics that fine-grained full tailings are difficult to deposit and consolidate, poor in physical and mechanical properties and the like, the physical and mechanical properties of the warehousing tailings are improved by adopting a mode of combining an upstream dam filling method with a mature process and a high-concentration tailing discharging process with relatively good safety and environmental protection properties and adopting targeted improvement measures, the problems that fine tailings are difficult to deposit and consolidate, the evaporation rate is low, environmental damage is caused by tail water seepage, and the mechanical property of coarse tailings is difficult to improve are solved, and the grading high-concentration tailing stockpiling process based on property improvement has the advantages of being low in water content, good in mechanical property, high in dam body safety coefficient, rapid in evaporation and drying of fine-grained tailings, rapid in deposition and consolidation, good in environmental protection property, improving the ecology of the tailings and the like.
