About 20 indium smelters and refineries in China's Shaoguan city, Guangdong province, have closed down after the provincial government ordered plants to install pollution control facilities, market participants told MB. Plants in Shaoguan, one of China's main indium production bases, have been closing for the past two months and now only two or three larger producers that have better pollution controls are left in Shaoguan, according to market sources. "With raw materials being so hard to source and pollution facilities being so costly, many of these smelters and refineries said that they might as well close shop," said a senior official from Shaoguan Smelter, one of the indium producers still working.
