我所用硫脲亚硫酸钠电解和硫脲鼓氧两种新工艺,将镀金废元件中的金解析出来,以便再生利用,变废为宝。人所共知,金是一种贵重金属,除用于世界硬通货币和装饰品外,随着科学技术的发展,应用范围越来越广,如首饰、纺织、陶瓷和玻璃、航空宇宙、电子、仪表等工业都少不了它。金在地壳中克拉克值很低,原生金矿工业开采品位只需5克/吨即可开采,含量仅有5×10~(-5)％,而镀金废元件中金的含量达0.1～0.3％,品位高于2000～6000倍,
I use thiourea sulfite electrolysis and thiourea drum oxygen two new technologies, the gold-plated waste components in the analytical out for recycling, turning waste into treasure. As we all know, gold is a precious metal, in addition to the world hard currency and decorations, with the development of science and technology, more and more applications, such as jewelry, textiles, ceramics and glass, the aerospace, Electronics, instruments and other industries are indispensable to it. Gold in the crust of the Clarke value is very low, native gold mining industry grade only 5 g / tonne can be mined, the content of only 5 × 10 ~ (-5)%, while gold-plated waste components of gold content of 0.1 to 0.3 %, Grade higher than 2000 ~ 6000 times,
