Overview of the treatment and utilization of waste residue

Gold mining will emit large amounts of waste rock, waste rock in order to influence environmental governance, to take on the waste rock segmentation process, used as a building stone, road stone or stone filling.

The tailings discharged from the gold production process account for more than 90% of the original ore. The concept of tailings is relative. The tailings often contain some useful ingredients that can be recovered under higher technical levels, such as sending cyanide leaching slag to a chemical plant as a raw material for sulfuric acid or recovering gold from tailings. South Gold Mine, Jiapigou Gold Mine). The tailings contain a large amount of chemicals, some of which are harmful to the human body, livestock, farmland, etc. If the tailings containing heavy metal ions and chemicals are discharged into the rivers, lakes, or rivers in the form of pulp, it will cause nearby waters, soil, and even groundwater. The pollution of resources brings a series of serious problems. Therefore, some mines mix tailings and cement into cementing materials and input them into the underground gob area. Some mines crush the soil on the tailings pond, planting trees and planting trees, and developing orchard. For the treatment of tailings, there is basically a tailings pond in gold mines.
