METHOD FOR RECYCLING INDIUM

摘要

PURPOSE: An indium recovering method is provided to collect the indium with high purity and to reduce a processing time by omitting additional purification processes. CONSTITUTION: An indium recovering method comprises next steps. Indium inclusion is melted by hydrochloric acid in order to manufacture indium solution(S1). Alkali is added in the indium solution and to make the Ph of the indium solution Ph 2.5~3.5(S2). The neutralized indium solution is matured(S3). The sulfurizing agent is added in the matured indium solution to make the Ph of the matured indium solution Ph 2~3. The sulfide is eliminated(S4).
