摘要

In order to obtain metallic agglomerated particles having a substantially spherical shape and stable particle diameters, the present invention comprises a circulation means for causing a flow of a solution containing metal to pass through a treatment unit and an external circulation path, substantially continuously extracting part of the solution in the treatment unit to the outside, and returning the flow of the solution to the treatment unit after passing through the external circulation path. The flow rate in the external circulation path is 1 m/sec or more, and an undiluted solution that contains at least some of reactants to be newly added is poured into the external circulation path.
