Platinum rare metallic oxide coated titanium anode/titanium electrode from Baoji Ruicheng Titanium Industry Co., Ltd. can recover copper from chloride wastewater (alkaline wastewater), sulphate wastewater (acid wastewater), as well as mixture thereof, with stable working process, corrosion resistance and long service life. The product anode has excellent conductivity performance, and is capable of effectively reducing over-potential and bath voltage. From aspect of environmental protection, etching process which is always concerned and will generate dangerous wastewater is turned into a clean process free from wastewater and pollution, thereby realizing the aims of high efficiency, energy conservation and low discharge
