A production plant was built in Huizhou, Guangdong, focusing on recycling spent precious-metal catalysts, cobalt-alloy scraps and residual ITO (indium-tin oxide) targets. Deploying core processes including chemical displacement, reduction, extraction and separation-purification, we achieved large-scale production of precious-metal feedstocks, indium ingots and cobalt powders, and established foundational capabilities in metallurgical-chemical operations and wet-chemical synthesis.
