Abstract

The invention belongs to the technical field of tailing pond treatment, and discloses a tailing pond selling method. The method comprises the following steps of step 1, preparing a filling material byutilizing mining waste rocks and mining tailings in a grading manner; step 2, dewatering the graded filling material; step 3, conducting slurry treatment of the graded filling material; step 4, filling. According to the method, replacement between waste rock mining and the tailing pond mining tailings is formed, specifically, the mining waste rocks are made into sandstone aggregates, and the mining tailings are used for filling a goaf formed by waste rock mining, so that benefit maximization of tailing pond selling treatment is achieved. Specifically, the mining tailings of the tailing pond are subjected to grading treatment, and coarse particle tailings are used as the sandstone aggregates to be sold after pollutants are deeply removed or innocent treatment is conducted. Oversize fine particle tailings are mixed with sandstone waste, and the goaf formed by mining the waste rocks is filled. Undersize fine particle tailings adjust the concentration of filling slurry, and can also be used as a preparation raw material of a novel cementing agent.

Description

technical field [0001] The invention belongs to the technical field of tailings pond processing, and in particular relates to a method for selling tailings ponds. Background technique [0002] The tailings pool is a place for storing metal and non-metal mines for ore sorting and then discharging the tailings. With the development of the economy, the social demand for mineral products has increased significantly, and the grade of available minerals has decreased day by day. The scale of development has increased accordingly, and the amount of tailings produced has continued to increase, making tailings stockpiles occupy a large area, serious environmental pollution, and many safety hazards have become increasingly prominent. [0003] There are nearly 8,000 tailings ponds in my country, ranking first in the world in total; among them, "head-top ponds" (tailings ponds with residents or important facilities within 1 km from the foot of the initial dam slope to the downstream tai...
