Problems solved by technology

However, due to waste rock piles and ore piles, the ores are of different sizes and are mostly angular. The plastic film is easily damaged and weathered, and it cannot prevent the groundwater from penetrating and invading the waste rock piles for a long time.

Embodiment 2

[0012] Embodiment 2 The alkaline waste water produced in the beneficiation process of non-ferrous metal mines is used for the sulfide-containing ore bodies, ore heaps, waste rock heaps, exposed slopes, and the surface of the mining operation surface to periodically immerse for a long time or Spraying, the time of each soaking or spraying in the dry season is 1-10 days, and then stop spraying for 2-20 days, which is a cycle; the time of each soaking or spraying in the rainy season is 1-30 days, Then stop spraying for 1-10 days, which is a cycle, and periodic cycle soaking or spraying will be carried out in both the dry season and the rainy season. The subsequent steps are the same as those in Embodiment 1, and will not be described in detail here.

[0013] For the characteristics of different non-ferrous metal mines, different acid wastewater quality, and different local climate conditions, topographic conditions and hydrogeological conditions, different soaking or spraying met...

Abstract

A process for radically treating the acidic sewage of non-ferrous metal mine includes spreading the alkaline ore tailings on the sulfide ore body, waste rock stack, mining surface and slope, periodically spraying the alkaline sewage (alkaline liquid, ore concentrate overflow liquid, and tailings overflow liquid) generated by dressing the non-ferrous metal ore, and collecting the osmotic liquid for reusing it for ore dressing.

Description

technical field [0001] A method for controlling the source of acidic wastewater in nonferrous metal mines, which belongs to the field of mine environmental protection technology, and especially reduces the generation of sulfide-containing ore bodies, ore heaps, waste rock heaps, exposed slopes, and mining operations in nonferrous metal mines from the source. Acid Wastewater Method. Background technique [0002] For sulfide-containing non-ferrous metal mines, especially in areas with a lot of rain, under the biocatalytic oxidation of thiophilic bacteria and other ore-leaching bacteria, oxygen in the air, water and sulfides act together to produce a large amount of sulfuric acid Roots and heavy metal ions in acidic wastewater, while acidic conditions are more conducive to the action of thiobacillus and other leaching bacteria and the dissolution of heavy metal ions. Thereby aggravating the production of acidic wastewater. If the acidic wastewater is not treated, it will caus...
