| titleOfInvention | A kind of high efficiency separation and the method for noble metal in recovery discarded circuit board |
| abstract | The invention belongs to metals resources recycle and reuse technology, a kind of high efficiency separation and the method for noble metal in recovery discarded circuit board, it is achieved the problem such as economic benefit and environmental benefit win-win in Disposal of Electronic Wastes.Initially with mechanical treatment technology, waste printed circuit board being ground into granule, then these granules are separated into metal and non-metallic material under high-pressure electrostatic effect, successively build Fe Cu high-temperature liquid-phase piece-rate system and Cu Pb relative low temperature liquid-phase separating system；In recycling waste printed circuit board, metalliferous material constituent element carries out selectivity Distribution dynamics in liquid-phase separating system, makes base metal, non-ferrous metal high efficiency separation, in almost all of concentration of precious metal to rich Cu phase；Then in conjunction with hydrometallurgical technology, from a small amount of rich Cu material concentrating noble metal, separate and extract noble metal, thus substantially reduce metal multicomponent separation and the consumption of chemical reagent in removal process, reduce the electron wastes harm to ecological environment. |
