Abstract:
The present disclosure provides an apparatus and a method for recovery of valuable metals. The apparatus includes an electrolytic chlorine producing bath, a dissolution bath disposed at a rear side of the electrolytic chlorine producing bath to perform leaching of a valuable metal content, a gas supplier connected to the dissolution bath to supply a carrier gas, a collection bath disposed at the rear side of the dissolution bath to collect a volatile material, a separation bath separating and purifying a leaching reactant generated in the dissolution bath, and chlorine and sodium hydroxide recirculation lines connecting the electrolytic chlorine producing bath, the dissolution bath and the separation bath. The apparatus permits recovery of valuable metals according to characteristics of the valuable metal, and the chlorine and sodium hydroxide recirculation lines of the apparatus provides optimized recovery rate and efficiency, thereby realizing economic feasibility.
