Currently gold mine heap leach ore mostly open-pit mining, waste so rarely used to fill mined-out area, and needs to find another waste disposal site. The selection of the site is generally in the valley near the heap immersion site. The lowest point in the valley should not be too close to the groundwater level, and the surface permeability is required to be low. There are drainage ditches around to prevent flooding. Downstream of the waste slag yard, the dam is usually blocked, and the well is provided with a drain pipe to discharge rainwater from the site. Outside the dam, there is a sump and a drain. The waste slag of the gold ore cyanide heap is mainly the waste ore after leaching and the sediment of a very small amount of carbonate, and the two are mixed and stored together. Since cyanide is easily decomposed under sunlight, it is washed before being discharged, so there is not much residual cyanide in the residue. If the waste residue is stored, a certain amount of bleaching powder is added every certain thickness, for example, 1 to 3 m. Thus, the cyanide toxicity in the waste residue is generally not harmful to the environment, and the cyanide concentration of the water flowing out of the waste residue field can also reach the open water source. Standard. However, in order to ensure absolute safety, the outlet of the waste slag yard should generally be set up with a pool. The concentration of cyanide should be checked regularly. If it exceeds the standards for open water sources, it should be treated in time, otherwise it will not be allowed to be discharged. The waste slag yard should eventually be greened by vegetation.
