Group 1 - The article highlights the growing importance of ruthenium oxide (RuO₂) in the recycling industry, particularly in Zibo, where overlooked industrial waste is becoming a new opportunity for precious metal recovery [1][2] - Ruthenium oxide is recognized for its high electrical conductivity and chemical stability, making it widely used in various industries such as electronic ceramics, titanium anode coatings, glass coloring agents, and military composite materials [4][5] - Zibo's industrial chain aligns well with the applications of ruthenium oxide, leading to significant amounts of ruthenium-containing waste entering recycling channels annually [5] Group 2 - Typical sources of ruthenium waste in Zibo include retired anode plates from electrode factories and residual materials from glass manufacturing and catalysts, with the metal value per ton often reaching tens of thousands of yuan [9] - The recovery process of ruthenium oxide involves precise analysis and specialized metallurgy techniques, including sample testing, chemical dissolution, reduction precipitation, and final product regeneration [9] - As of August 2025, the recovery prices for ruthenium oxide in Zibo vary based on the ruthenium content, with prices ranging from 80 to 150 yuan per gram depending on the material form and purity [9] Group 3 - Several industrial enterprises in Zibo are profiting from the ruthenium business, with examples including an electronic ceramics factory earning over 100,000 yuan quarterly from waste recovery and intermediaries making substantial profits by connecting electrode factories with recycling companies [10]

Group 1 - The recovery price of ruthenium oxide (RuO) typically ranges from 50 to 100 yuan per gram, influenced by purity, market demand, recovery processes, and environmental regulations [4][5] - Some recovery merchants offer prices around 90 yuan per gram, while others may quote lower prices, such as 80 yuan [4] Group 2 - Purity directly affects the recovery value of ruthenium oxide, with a minimum ruthenium content of 65% to 70% required for optimal pricing [5] - Market demand in the electronics and catalyst sectors significantly impacts the recovery price [5] - Different purification technologies can alter the final recovery costs and quotes [5] - Strict environmental regulations may increase recovery costs, thereby affecting the final price [5] Group 3 - When selecting a recovery merchant, it is essential to verify their qualifications and relevant licenses [8] - Assessing the technical capabilities of the recovery merchant, including advanced purification and testing equipment, is crucial [9] - Quality recovery merchants typically provide payment within 24 hours post-testing, while the industry average is 3-5 working days [10]
