Innovative paths for germanium recycling enterprises to enhance competitiveness include: 1) Multi-source synergistic recycling technology (co-production from zinc slag/coal ash/fiber waste, increasing germanium enrichment efficiency by 5 times); 2) Selective organophosphonic acid extraction process (Ge recovery rate >99.5%, separation factor…
The core pathways for optimizing tin recovery processes using ultrasonic-assisted leaching technology include: 1) Cavitation effect enhancing interfacial reactions (micro-jet pressure >20MPa, leaching rate increased by 3 times); 2) Low-frequency high-power ultrasound (20kHz², leaching time shortened from 8h to 1.5h);…
The core pathways to achieve green and low-carbon germanium recycling include: 1) Pyrometallurgical process transformation (oxygen-enriched smelting reducing energy consumption by 30% + flue gas waste heat power generation); 2) Hydrometallurgical system optimization (low-concentration leaching reducing acid consumption by 40%…
