《电解退金新工艺》是我所近年来研究的新成果,已于一九八二年十二月通过了技术鉴定。电子工业生产的电子元件,成品率低,废品量大。这些废电子元件有相当量的镀金废件。对这种镀金废元件金的回收,现行的工艺是陈旧落后的,如氰化法、酸蚀法、碘化法、逆王水法、铅熔法、电解法,存在着剧毒,环境污染等问题。本所研究的硫脲电解退金新工艺克
The new technology of electrolytic gold refinishing is a new achievement I have studied in recent years and passed the technical appraisal in December 1982. Electronic components produced in the electronics industry have low yield and large quantities of scrap. These waste electronic components have a considerable amount of gold-plated scrap. The recovery of gold-plated waste gold components, the current process is outdated, such as cyanide, acid etching, iodination, inverse Wang water method, lead melting method, electrolysis, there is a toxic, environmental pollution and other issues .
