Mine tailings discharge of dry sense of ore into the concentrator via crushing, grinding and sorting, after homework, useful minerals in the ore sorted into one or more of the concentrate product. Places pulp tailings discharged in the state. Fine mineral was smaller, non-ferrous metals concentrator fine mineral rate is generally only 10-20%; a large number of tailings yield is generally 80% to 90%; even bigger. If a daily processing of small ball mill liner 100t of the concentrator, tailings daily emissions of up to 80 ~ 90t or more; high-grade ore, fine mineral rate, the tailings is low. If not properly handle a large number of tailings, great harm. Concentrator tailings discharged water often contains a lot of chemical and hazardous substances. Its source is added during beneficiation and ore flotation reagents metal element, a common cyanide, xanthate, black medicine, pine oil, copper ion, lead ion, zinc ion, and in some cases may have arsenic, phenol mercury. Tailings water can not reach these harmful substances emission standards, the human body, animals, fish and farmland are harmful. In the current level of technology, some precious metals, rare metals can not be recycled, but with science and technology to improve the mill tailings useful components can be re-exploited. Tailings comprehensive utilization of resources at home and abroad have been many instances, such as copper, Hubei Province recorded Mine Tailings rich in gold, silver, copper, iron and other useful components, in recent years, with the development of mineral processing technology in 1985, the Mine use of weak magnetic - intensity magnetic separation technology for Tailings, the recovery of tens of thousands each year t of iron ore from the tailings, the number value for the yuan, is now being further regrinding tailings re-election, so that tailings Gold, silver, copper, iron and other useful minerals to be fully recycled, so much economic progress in mine.

A simple understanding of the two with the ball mill method called two with the ball method, it is to use the size of the two different specifications, and both the diameter difference between the larger ball for grading. On the theory that a large gap between the ball from small balls to fill in order to fully enhance the bulk density of the ball. Thus, one can improve the impact strength and impact of the number of the first positions, in line with features that bin grinding media, on the other hand, higher bulk density can be able to get some material abrasive. In two match balls, big balls main function is the material for impact crusher. First, the role of small ball filling the gap between the big ball, increasing the bulk density of the grinding media to control the flow of materials ceramic ball, grinding capacity increase; the second is the role of energy transfer from the large ball impact energy transfer to the material; Third The gap in the coarse particulate material squeezed out and placed in a large ball of the impact zone. In the multi-stage with the ball in for the ball impact, impact times, the ability to control material flow requirements are based primarily on average ball diameter, that is subject to a variety of specifications ball in. In the two-stage with the ball, the ball's impact, the impact of the number of times the diameter of the large ball mill parts decisions, and the ability to control the flow rate of the material is mainly determined by the diameter of the ball loadings affected large ball diameter is small , thus easing the impact, frequency and control the impact of conflict between material flow capability. In contrast, the two-stage method is relatively simple with the ball, when determining grading parameters considered easy to do. From production changes, along with the material hardness and grain size increases, conflicts with the ball in the performance of multi-level impact and material flow control ball between the more prominent, and therefore production fell more obvious. In the two with the ball in this conflict does not exist, because it can be big, small balls to satisfy the material to impact and flow control capability requirements, and therefore production did not change significantly, reflecting the superiority of two with the ball .
