Abstract:This article introduces the new generation fully automatic electromagnetic gravity separation equipment LONGi Magnet Co., Ltd. It solved some problems in the production application of the older one which is successfully applied to improve Fe grade in copper tailings. In response to the difficulty of extracting iron from some copper mine tailings through the iron separation process, it is necessary to replace the flotation process. The research and development process, from laboratory data analysis to industrial solution customization, to data analysis during production, has demonstrated the superior performance and reliability of the new generation fully automatic magnetic flotation separation. The necessity of continuing fine sorting of magnetic gravity separation products has been verified. A new route has been opened up for improving the quality of copper tailings and iron products both domestically and internationally.
