The precipitation unit precipitates the rhenium ions in an ammonium rhenate form from the rhenium ion containing ammonia. The residual liquid treatment unit evaporate-crystallizes the residual solution after separating the precipitated ammonium rhenate into solid and liquid, and precipitates the rhenium ions in the ammonium rhenate form by re-dissolving the obtained crystal in ammonia.
