2010-1-1  1.. IntroductionIndium is an important metal used in electrical industries extensively (Alfantazi and Moskalyk, 2003).Sphalerite present in sulfide ores is the main mineral source for the zinc and indium production (Pavia, 2001).The typically traditional process for extracting indium from In–Zn concentrates includes the following steps.
