Abstract

The invention discloses a copper tailing disposal method. The copper tailing disposal method comprises the steps that component detection is carried out on copper tailings, and the heavy metal contents of exploited barren rocks and milltailings are analyzed and determined separately; the percentage content m of exploited barren rocks obtained after the exploited barren rocks and the milltailings are mixed is calculated to enable the heavy metal content of the mixture of the exploited barren rocks and the milltailings to be within a safe range; particle size analysis is conducted on the tailings, breaking disposal is conducted on the exploited barren rocks, the broken exploited barren rocks are screened, and the percentage content n of exploited barren rocks obtained after the screened exploited barren rocks and the tailings are mixed is determined according to the particle size of the tailings; and the percentage content m is compared with the percentage content n, the maximum value ofthe percentage content m and the maximum value of the percentage content n are taken as the mixed content of the exploited barren rocks, and the exploited barren rocks and the milltailings are mixedand compacted. The pollution of the copper tailings to the environment is avoided, and meanwhile the reuse rate of resources is improved.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a method for treating copper tailings. Background technique [0002] In the process of copper polymetallic sulfide mining and dressing and smelting, the production process usually used is: mixed flotation - fine mixing and regrinding - copper and sulfur separation - floating tail magnetic separation process to recover copper, gold, silver, sulfur, iron and other valuables valence components. During the beneficiation process, a large amount of wastewater containing suspended solids and flotation agents is generated, which is collected in the tailings slurry. The tailings of the dressing plant are classified, the coarse sand is used for underground filling, the fine tailings are concentrated-high-efficiency pressure-filtered-filter cakes are stacked, and the overflow and filtrate generated are processed and reused for production. During the tailings treatment process, a large ...
