Patent number: 10982299Abstract: A method for comprehensively processing noble lead provided and utilizes two instances of vacuum distillation to realize an open circuit of arsenic, lead, antimony and bismuth and the high-efficiency enrichment of precious metals of gold and silver, and can obtain elemental arsenic, a lead-bismuth-antimony alloy, a silver alloy and a copper alloy, respectively. The lead-bismuth-antimony alloy, the silver alloy and the copper alloy are processed by oxidation refining, electrorefining and chlorination refining to obtain refined lead, refined antimony, antimony trioxide, electrolytic silver and electrolytic copper, and to realize gold enrichment. The entire process has advantages of high metal direct yield, low energy consumption, short flow chart, simple equipment, etc., and vacuum distillation belongs to a physical process in which the alloy can be separated only by means of the difference in saturated vapor pressure between the metals, without generation of wastewater, waste gas and waste residue.Type: GrantFiled: March 19, 2019Date of Patent: April 20, 2021Assignees: Kunming University of Science and Technology, Kunming Dingbang Technology Co., Ltd.Inventors: Bin Yang, Dachun Liu, Wenlong Jiang, Guozheng Zha, Baoqiang Xu, Weiping Dai, Yifu Li, Qingchun Yu, Xiumin Chen, Hongwei Yang, Yang Tian, Yong Deng, Fei Wang, Heng Xiong, Jia Yang, Tao Qu, Lingxin Kong
