According to the latest statistics of the report on the conservation and comprehensive utilization of China's mineral resources (2015) released by the China Academy of land and resources economics,The accumulated stockpile of tailings and waste rocks in China is close to 60 billion tons, of which 43.8 billion tons are piled up, 75% of which are coal gangue and waste rocks produced by iron and copper mining. 14.6 billion tons of tailings are piled up, 83% of which are formed by iron ore, copper ore and gold ore mining, with great potential for comprehensive utilization.
How to use the current key issues. Tailings are the "waste" discharged by mining enterprises under certain technical and economic conditions, but most of them contain various non-ferrous, black, rare earth and non-metallic minerals, which are valuable secondary resources. When the technical and economic conditions permit, it is necessary to develop it again. but before technological and economic conditions permit,How should we use these tailings?
First of all, we should try our best to do a good job in the comprehensive recovery and utilization of useful components of tailings resources, and adopt advanced technology and reasonable technology to re-select tailings to maximize the recovery of useful components in tailings, which can further reduce the number of tailings. Some concentrators are developing in the direction of no tailings.
2. Tailings are used as filling material for underground mining goaf, I .e. water sand filling material or cemented aggregate. Tailings are used as filling materials in goaf,The most ideal filling process is the whole tailings filling process.. In the production are used in the use of tailings in the coarse part of the goaf as filling. The tailings of the beneficiation (belt conveyor) plant are discharged and sent to the tailings preparation section for classification, and the coarse sand part is sent to the underground goaf, while the fine sand part is stored in the tailings pond. This tailings treatment method has been applied at home and abroad.
3, the use of tailings fired new building ceramsite, with the new ceramsite as the main raw material, it will be made into a new self-insulation wall building materials ceramsite brick or puffed block, the block has good insulation, light weight, high strength, sound insulation and moisture-proof and other advantages. It is suitable for the bearing structure and enclosure wall of industrial and civil buildings. It is an ideal new building material to realize the integration of structure, enclosure and thermal insulation. Its main technical indicators are in the leading position of innovation at home and abroad, which is very suitable for the current and future development trend of the construction industry. National building materials industry leaders and experts call it"New products that bring revolution to Chinese wall materials”。
4, with tailings to build roads, pavement materials, anti-skid materials, coastal farming, etc.; In the tailings accumulation field covering earth, planting crops or afforestation; The tailings pile is stored in a specially built tailings pond, which is the most widely used tailings treatment method in most concentrators.
Tailings filling is the most economical and environmentally friendly treatment method., or use tailings to burn new building ceramsite, and use the new ceramsite as the main raw material to make it into a new type of self-insulation wall building material ceramsite brick or puffed block. The new type of tailings self-insulation puffed block relies on its advantages of light weight, heat preservation, fire prevention, durability, earthquake resistance, sound absorption, waste utilization, easy prefabrication and easy transportation, will be in the implementation of the modernization of the construction industry and the wave of green building ushered in the opportunity of rapid development, to create a green city.
Yutai Heavy IndustryResponding nations quickly unfold tailingsFilling industrial pumpThe design of research and development. It is understood that Yutai Heavy Industry tailings filling industrial pump technology and complete sets of equipment have been applied in more than 70 metal mines, chemical mines and coal mining enterprises under different geological conditions at home and abroad, and its tailings filling system technology has reached the domestic leading and international advanced level. It can solve the problems of mine safety production, ecological environment, resource utilization rate, etc., and is conducive to the construction of a harmonious green mine in the mining area.
