| description | The invention discloses a method of comprehensively recycling copper and iron minerals in metal tailings. The method includes three steps: a first step is a tailing preprocessing process, a second step is a fine-grained tailing first-copper-last-iron process and a third step is a coarse-grained tailing first-iron-last-copper process. According to the method, the tailing preprocessing process includes a screening slag removing process, a slurry mixing stirring process, a tailing classification process and the like, most large-block waste rock and organic impurities in the tailings can be removed, so that the component of the tailings is more single, the amount of sodium silicate during slurry mixing stirring is less, and the sorting efficiency of the minerals can be improved, so that the sorting effect of the mineral particle size is better. The fine-grained tailing first-copper-last-iron process is adopted, the tailing grinding can be reduced, the sorting effect of fine-grained copperis better, the content of |
