Mining is the oldest industry in our country, but also is the basic industry of national economy, involving agriculture, light industry, chemical industry, metallurgy, machinery fields, construction, energy, transportation, national defense and people's daily lives, and It has penetrated into the high-tech industries such as aerospace and information. It can be seen that mining has an irreplaceable important role in the development of China's economy. However, while vigorously developing mineral resources, a large amount of ore dressing wastewater will be produced, which will cause damage and pollution of the ecological environment and bring about a series of negative effects. The wastewater discharged from the ore dressing and ore dressing process is called ore dressing wastewater. In non-ferrous metal beneficiation, the treatment of lt ore flotation method is 4~7m, the water is 20~26m, the floating magnetic connection is 23~27m, and the heavy float is 20~30m, which removes the water used for recycling. Part of the amount of water consumed is accompanied by tailings flowing out of the concentrator in the form of tailings pulp. Especially in the flotation process, in order to effectively select the useful components, it is necessary to add a large amount of flotation reagents in different operations, mainly collectors , foaming agents, organic and inorganic activators, inhibitors, dispersion At the same time, some metal ions, suspended solids, decomposition products of organic and inorganic chemicals, etc., remain in the beneficiation waste solution to form a beneficiation wastewater containing a large amount of harmful substances. The direct discharge of the ore dressing wastewater will cause serious pollution to the environment, which makes the sewage discharged from mines and ore dressing in China reach 12 to 150 million tons per year, accounting for about 30% of the non-ferrous metal industrial wastewater. How to prevent the pollution of ore dressing wastewater to water bodies and farmland is one of the hot issues that people are currently paying attention to.
