The chlorination of indium in the ground powder of liquid crystal displays and selective liquid extraction of volatile components were investigated in order to obtain fundamental data for developing an efficient recovery process of indium from secondary resources. The sample was heated at terminal temperatures ranging from 473-973 K in a chlorine stream with a fixed bed reactor. While indium volatilized by chlorination of the metallic form below 573 K, indium chloride accompanied the volatilization above 573 K according to the carbochlorination reaction of indium oxide in the ground powder. All indium contained in the powder was released by 973 K. Coexistent metals of chromium, iron and titanium in the powder were also released with indium during chlorination. Indium could be concentrated successfully by the temperature control in the cooling zone of the reactor and extraction of volatiles with diethyl ether.
