Due to the mass exploitation and utilization of mineral resources, available resources are dwindling, causing lower raw ore mining taste and higher demand of the Ore Beneficiation in the subsequent processing, such as smelting. At the same time, the environment protection consciousness of human strengthens day by day. All the reality pushes dressing equipment in the direction of larger sizes, higher quality, higher efficiency and lower energy consumption.
China has rich mineral resources, but a lot of tailings have to be discharged from beneficiation flowsheet due to the quite low grade of most mineral resources. According to statistics, since 2000, the annual tailing production of China mines has been up to more than 600 million tons. According to this calculation, the total pile volume of current tailings is about 80 million tons. These tailings not only occupy the large area land and pollute the environment of mining and peripheral area which forms security risk but large capital has been spent on tailing warehouse maintenance every year. Consequently, the comprehensive tailings utilization and emission reduction work, which can turn waste into treasure and harm into good, relieve the double pressure of resource and environment.
Tailings are the waste discharged from the ore grinding and dressing process on the precondition of certain economy technology. Regarded as a compound silicate mineral material due to the certain metal and nonmetal mineral, it is also the major source of industrial solid waste which will do serious harm to environment and in it. So it can be considered as a latent secondary resource with fine granularity and large volume. In other words, tailings have double characters, namely secondary resource and environmental contamination. The advancement of science and technology, the scientific infiltration between disciplines and mutual fusion among various industries, the endless emergence of new structures and new materials, new technology and new processing techniques and the widely use of electromechanical integration and automatic control technology promote innovation in the mineral processing equipment.
