Mine tailings treatment is a modern production method that realizes “no tail, no waste, no pollutionâ€, making the mine greener.
The tailings treatment is divided into three parts: one, tailings re-election, two, tailings backfilling, and third, tailings making raw materials. The tailings re-election is to re-select the tailings after sorting; the tailings backfilling is to concentrate and dewater the tailings for backfilling in the mine goaf, and the raw material for the tailings is to make the tailings dry for tailings. Among them, useful materials are used to make raw materials, such as fertilizers and building materials.
So what are the conditions for using these three tailings treatment methods?
Tailings re-election
Conditions of use: Generally suitable for small concentrate yield. Non-ferrous metal beneficiation plant fine mineral rate is generally only 10-20%; a large number of tailings, the yield is generally 80% to 90%; even more.
Advantages: It can improve the efficiency of sorting and reduce the waste of tailings resources. Maximize the recovery of useful components in tailings to further reduce the amount of tailings. Avoid tailings dam breaks.
Tailings backfill
Conditions of use: Suitable for large mines. After the ore is mined and sorted, the tailings waste is backfilled into the goaf.
Advantages: It helps to stabilize the mine, prevent surface subsidence, and is safe and environmentally friendly.
During mining, the stone pillars in the mine can be re-harvested to increase the ore recovery rate by more than 20%. Achieve tailless emissions.
Tailings production raw materials
Conditions of use: The raw materials for tailings production are only for mine applications below 500,000 tons. The chemical composition contained in the tailings discharged after ore dressing is very close to the materials required for construction and fertilizer, so it can be used as raw materials for production and improve the comprehensive utilization rate of tailings.
Advantages: Improve comprehensive utilization rate, reduce environmental pollution, and save a lot of land. In addition, it is in line with the state's policy of promoting the development of circular economy and reducing resource consumption.
The comprehensive utilization of tailings has many advantages, but it is also not necessary to blindly choose the tailings treatment method. It needs to be comprehensively considered according to the form of the mine and the type of ore.
