[Problem] To provide a heavy metal separation system which, at low cost, uses magnetic powder to efficiently separate and recover heavy metals from objects being treated. [Solution] In these heavy metal separation systems 100, 200, heavy metal components contained in objects being treated are adsorbed onto magnetic powder, and the heavy metal components are transferred to an acid bath 40 together with the magnetic powder by a magnet part 60. The state of adsorption between the magnetic powder and heavy metal components is undone by an acidic solution in the acid bath 40, and the magnetic powder is discharged to a magnetic powder recovery unit 70. In the magnetic powder recovery unit 70, the heavy metal components and the magnetic powder are separated. Through the functional operation thereof, heavy metal components can be efficiently separated and recovered at low cost from objects being treated, such as incineration ash. 本发明提供种重金属分离系统，其可使用磁性粉而低成本且高效率地将处理对象物中的重金属分离回收。该重金属分离系统100、200将处理对象物中的重金属成分吸附于磁性粉，通过磁石部60
