Method for preparing filtering material from copper tailings and application
The invention discloses a method for preparing a filtering material from copper tailings. The method comprises the following steps of: mixing pretreated copper tailings, water, a modifier and an adhesive to prepare a raw material with the water content of 10-30%; and performing injection molding and roasting on the raw material so as to obtain the filtering material. The energy-saving and environment-friendly filter material is prepared on the premise of solving the problems of low comprehensive utilization rate of metal tailings and the like, and is applied to filtration and dehydration of mine concentrates and solid-liquid separation in the industries of coal, fine chemical engineering, papermaking, pharmacy, chemical fibers, foods, environmental protection and the like, so that the resource utilization of the tailings is efficiently realized.
本发明公开了一种利用铜尾矿制备过滤材料的方法，即将预处理的铜尾矿、水、改性剂、粘合剂混合制成含水率为10%~30%的生料，再经过注模、焙烧，制得过滤材料，在解决金属尾矿综合利用率低等问题的前提下制备节能环保型过滤材料，并将其应用于矿山精矿的过滤脱水及煤炭、精细化工、造纸、制药、化纤、食品、环保等行业的固液分离，进而高效地实现尾矿资源化利用。
