Mine tailings of several comprehensive utilization methods, need to have their own conditions of application, it needs according to the physical and chemical properties of tailings and mineral components, select the appropriate use of the way, according to the development and construction of the mine needs, near the mine The need for building materials, and consider the Kuangshan transportation, electricity, materials, fuel and other supply conditions to determine a reasonable.crusher parts

For example, a mine underground to be filled, and the mine tailings are not easy to weathering hydrolysis, do not produce toxic and harmful gases, grain size of most of 0.037 mm or more, the tailings can be used as underground filling materials; Quartz is very high, the local demand for building materials, you can consider the use of tailings produced autoclaved silicate brick, tile, when the tailings of the quartz content is high, while harmful components (sulfur, iron, Etc.) content is very small, but also can be used as raw materials for glass; and if the mine produced when the tailings containing CaO higher, and MgO content is very low, it can be used as cement raw materials; Such as when the mine output of the tail extension is rich in A1203 and Si02, you can consider the raw materials used as refractory materials. In addition, for the complex tailings, when the tailings in the mineral composition and chemical composition in line with the requirements of raw materials for the production of cast stone products, can be used to try casting products, or dry burning ceramic. In short, the comprehensive utilization of tailings should be based on the specific conditions of the mine, a comprehensive consideration to determine.

In addition, the tailings will contain radioactive elements, if used for building brick materials applicable, will endanger human health, so the use of building materials used to recover the tailings contained in the trace of useful metals and rare metals and so on. To this end, in the use of tailings, the tailings should be the full analysis of chemical composition, particle size composition analysis, pharmaceutical and oil content analysis and so on.
