国内电解精炼法制备高纯金综述

摘要

介绍了高纯金的研究意义及电解精炼法制备高纯金的基本原理.从电解电源、阴极板的设计、电解环境、电解工艺、标准状况及主要生产厂家等方面,综述了国内电解精炼法制备高纯金的生产研究现状,并提出了制备满足新国标要求的5N高纯金的研究方向.%The significance and the basic principle of high-purity gold prepared by electro-refining were introduced. The domestic production status of high-purity gold by electro-refining were reviewed from the aspects of electrolysis power, cathode plate design, electrolysis environment, electrolysis process, standard condition and main manufactures. In the meantime, the research prospect of developing 5N high-purity gold process was also forecasted.
