Method for recovering lead carbonate from lead sulfate-containing mineral

A method for recovering lead carbonate from lead sulfate-containing mineral comprises the following steps: adding calcium hydroxide and an activating agent into the lead sulfate-containing mineral, slurrying in an aqueous solution, filtering to obtain filter residues, adding acetic acid and an acetate solution into the filter residues, and dissolving lead oxide into lead acetate to enter the solution; and finally, adding a precipitant carbon dioxide into the lead acetate solution, and precipitating to obtain the product lead carbonate. According to the invention, low-cost calcium hydroxide and a conversion activator are adopted to convert lead sulfate which is difficult to treat into lead oxide which is easy to treat; acetic acid and acetate are used for leaching lead oxide in the conversion slag, and selective lead leaching is achieved. According to the method, the conversion rate of the lead sulfate is more than 95%, the direct recovery rate of the lead is more than 95%, and the high-purity lead carbonate i
