Publication number: 20100275730Abstract: A method is disclosed for recycling precious metal from used printed circuit boards. The used printed circuit boards are roasted with plasma at 800 degrees Celsius for less than 10 minutes, thus producing exhaust and residue that contains the precious metal. The exhaust is treated with an exhaust-treatment system before it is released to the atmosphere. The residue is ground and turned into scraps of a diameter smaller than 2 mm. The scraps are subjected to magnetic separation, thus separating ferromagnetic scraps from non-ferromagnetic scraps. The ferromagnetic scraps are refined. The non-ferromagnetic scraps are screened, thus separating tiny non-ferromagnetic scraps from big non-ferromagnetic scraps. The tiny non-ferromagnetic scraps contain silver and gold. The big non-ferromagnetic scraps contain copper.Type: ApplicationFiled: January 7, 2008Publication date: November 4, 2010Applicant: ATOMIC ENERGY COUNCIL - INSTITUTE OF NUCLEAR ENERGY RESEARCHInventors: Wen-Cheng Lee, Ching-Hwa Lee, Ching-Liang Chen, Fu-Jen Yeh, Hei-Yi Chen, Yun-Hua Chen
