Why Geomembrane Impermeable Materials Suitable for Tailings Disposal
When tailings are piled up, they are prone to flow and collapse, causing vegetation damage and injury accidents, especially in the rainy season when they are prone to collapse and landslides. The dam body of the tailings pond is relatively high, and there are hidden dangers of insecurity.
The composition of tailings and residual dressing reagents are seriously damaging to the ecological environment, especially the tailings containing heavy metals, in which sulfides produce acidic water to further leach heavy metals, and their loss will cause harm to the entire ecological environment.
At present, the treatment method of tailings is generally used as the filling material of the underground mining goaf, that is, water sand filling material or cement filling aggregate; or some directly cover the tailings accumulation field with soil to plant crops or plant trees. afforestation. In fact, the most economical treatment method of tailings is tailings sand making and raw materials for construction materials.
