摘要： PROBLEM TO BE SOLVED: To provide a dissolution method for easily and surely attaining both of: dissolving Zn contained in a Zn-containing generated substance close to the Zn-concentration of the Zn-dissolution capacity of an ammonium carbonate solution to be used; and avoiding an excessively dissolved state or an oversaturation state where Zn is dissolved to concentration equal to or higher than the Zn-dissolution capacity of the ammonium carbonate solution to be used, in a method for producing zinc carbonate by a dissolution method using ammonium carbonate. SOLUTION: Before performing a dissolution process for dissolving a Zn-containing generated substance into an ammonium carbonate solution, the content of easily soluble Zn in the Zn-containing generated substance is obtained by analyzing a sample solution obtained by dissolving the Zn-containing generated substance into an ammonium carbonate solution having a composition equal to that of the ammonium carbonate solution used in practical dissolution. Then, the blending ratio of the Zn-containing generated substance to the ammonium carbonate solution is determined based on the obtained content so that the blending amount of easily soluble Zn from the Zn-containing generated substance becomes 80-100 mass% of the Zn-dissolution capacity that is determined by the composition of the ammonium carbonate solution, and thereafter, the dissolution process is carried out.
