Embodiment Construction
[0024] The technical characteristics of the present invention will be further elaborated below in conjunction with specific embodiments.
[0025] The invention is a method for extracting cobalt from tailings, comprising the following steps:
[0026] (1) After pulverizing the tailings to a maximum particle diameter of 1-2mm, adding the pulverized tailings powder to an inorganic acid solution for leaching, and adding alkali to remove excess inorganic acid impurities after the leaching reaction is terminated;
[0027] (2) The mixture obtained in step (1) is separated from solid to liquid, and all the separated liquid is taken out as mixed liquid I for subsequent use;
[0028] (3) Grind the solid tailings powder obtained from the solid-liquid separation in step (2) until the largest particle size is 0.8-1.6mm, add the pulverized tailings powder into the inorganic acid solution for leaching, and add alkali to remove excess inorganic after the leaching reaction is terminated acid i...
