영어 초록
Fundamental experiences have been studied for development of pre-treatment process of Sn by-prod-ucts such as solders. Dry and wet separation/recovery processes were considered by the differences of physicalproperties. The by-products, which are analyzed by solder metal and oxides. The metal and oxide were simplyseparated by dry ball-milling process for 12 hours, after that recovery metal powder might be reusable as lead orlead-free solders. In terms of wet separation process, samples were dissolved in HNO3+H2O2 and the precipita-tion were analyzed by SnO2. Overall efficiency of recovery might be increasing via developing simple pre-treat-ment process.
