In the sand washing production line , the ore dressing operation is very important. With the increase in environmental protection in recent years and the tight supply situation of domestic mineral resources, we have to use the tailings that were once overlooked. The tailings are ignored because the residue cannot be further sorted. However, with the development in recent years, we have found that tailings are not completely useless waste, and often contain other ingredients that can be used for other purposes. The processing technology and development and utilization can effectively “turn waste into treasure”, which not only eases the resources and environmental pressure but also realizes the comprehensive utilization of tailings! The tailings zero discharge system is a specialized treatment system specially developed for the tailings dry discharge and tailings slurry zero discharge in the mine beneficiation industry. Compared with the traditional tailings treatment method, what ar
