ZK SEPARATION Decanters Application in Tailing Management
The ZK centrifuge is used to dehydrate the tailings sludge to form dehydrated tailings and then store them, ensuring the long-term safety of the tailings pond. At the same time, it also meets the environmental protection standards, and effectively alleviates the difficulty of water use in mining operations. Because, in the dehydration treatment of tailings, our centrifuges can remove the water in the tailings to the greatest extent, and can effectively recover the waste water, and then it can be recycled in ore processing operations. At the same time, our equipment is designed with anti-wear protection for the tailings sludge treatment, which will greatly extend the effective working time of the ZK centrifuge. In addition, our centrifuges can also be used for waste processing in the beneficiation process.
