Application of andradite as As (III) adsorbing material

The invention discloses application of andradite as an As (III) adsorption material, andradite has excellent adsorption performance on As (III) in a solution, can effectively adsorb and solidify dissolved arsenic and widen the application range of andradite, and andradite is obtained by magnetic separation, grinding and activation of nonferrous metal tailings, so that the development and utilization rate of tailings resources is increased, and the application range of andradite is widened. The pressure of mineral resources and the environment is relieved, high-value utilization of the tailings is realized, and the method has very important significance on environmental protection of mining areas. 本发明公开了一种钙铁榴石作为As(III)吸附材料的应用，钙铁榴石对溶液中As(III)具有优异的吸附性能，能够有效吸附固化溶解态砷，拓宽了钙铁榴石的应用范围，且钙铁榴石是从有色金属尾矿磁选分离和研磨活化得到，提高了尾矿资源开发利用率，缓解了矿产资源和环境压力，实现了尾矿高值化利用对矿区环境保护具有很重要的意义。
