| description | The invention belongs to the wet method metallurgy field, which is used for extracting metal from an aqueous solution, and concretely relates to a method for extracting metal in the aqueous solution. The method comprises the following steps: 1)immersing ore containing metal in a dissolve immersion pool; 2)filtering the aqueous solution for leaching ore, filtering the solid substance and then removing, keeping a metal-containing mother liquor; 3)controlling ore amount and dissolve immersion time, wherein the metal content in the mother liquor is more than 5g/liter; 4)arranging a copper electrode and an iron electrode in the electrolytic bath, separating the copper electrode and the iron electrode by a proton channel membrane , respectively dumping the bacteria liquid and the mother liquor; 5)turning on the power switches on the copper electrode and iron electrode, dumping bacteria liquid in the electrolytic bath at copper electrode side, realizing microbe charging, and performing self generating to realize electrolysis, and using a primary cell electrolytic method for extracting metal. The method breaks the limitation of current restriction due to internal resistance, and has the effects of high energy conversion efficiency and high electrolytic quality of primary cell. |
