  Tailing Processing Relieves the Double Pressures by YIFAN Crusher
  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 wastes 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 in it, it is also the major source of industrial solid waste which will do serious harm to environment and. 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.
  Nowadays, the development of secondary tailing beneficiation is pretty rapid. The crushing machine and grinding machine produced by Henan YIFAN, such as jaw crusher, impact crusher, cone crusher and sand maker, can be used for tailings grinding and secondary ore beneficiation which is able to separate the nonferrous metal and rare metal (vitriol, titanium, cobalt and scandium) from the ore tailing. Meanwhile, the research and application on building material turned from tailing or chats has undergone for 20 years. Chats and tailings can be used for ballast of highway or railway and...
