Publication number: 20250075289Abstract: Provided is a method for preparing high-purity indium (In). The method for preparing the high-purity In includes: distilling refined In to obtain an In vapor-containing gas; and condensing the In vapor-containing gas to obtain the high-purity In; where the distilling is conducted at a temperature of 1,000° C. to 1,100° C. under a vacuum degree of 1.0×10?3 Pa to 5.0×10?2 Pa; and the condensing is conducted at a temperature of 700° C. to 900° C. under a vacuum degree of 1.0×10?3 Pa to 5.0×10?2 Pa. The In vapor-containing gas is obtained by controlling the temperature and vacuum degree of the distilling to evaporate In and impurities with a vapor pressure higher than the In. The temperature and vacuum degree of the condensing are adjusted to condense the In in the In vapor-containing gas.Type: ApplicationFiled: August 15, 2024Publication date: March 6, 2025Inventors: Lingxin KONG, Jian PANG, Bin YANG, Baoqiang XU, Wenlong JIANG, Junjie XU, Dachun LIU, Yang TIAN, Yong DENG

Publication number: 20240328022Abstract: This invention presents an electrochemical metallurgical technique for extracting metals and sulfur from metal sulfides, offering an adjustable composition and mechanical properties during electrode preparation. The metal sulfide anode, submerged in an electrolyte with a cathode made of materials like titanium, copper, stainless steel, lead, zinc, aluminum or graphite, undergoes electrolysis. This process oxidizes sulfur in the metal sulfide to the anode and releases metal ions into the electrolyte, where they're reduced at the cathode. The method yields metal at the cathode and sulfur at the anode, with minimal environmental impact, low investment, and straightforward process.Type: ApplicationFiled: June 14, 2024Publication date: October 3, 2024Inventors: Jia Yang, Kanwen Hou, baohong Wei, Jiancheng Qian, Baoqiang Xu, Bin Yang, Dachun Liu, Wenlong Jiang, Yong Deng, Yifu Li, Yang Tian, Heng Xiong, Fei Wang, Qingchun Yu, Hongwei Yang

Publication number: 20240287644Abstract: Provided is a recovery method for valuable metals in copper anode slime. By using the recovery method of the disclosure, selenium, copper, tellurium, arsenic, lead, bismuth, and precious metals gold and silver in the copper anode slime are recovered. The method adopts two-step vacuum carbothermal reduction to replace reduction smelting of anode slime and stepwise blowing of noble lead in the traditional pyrometallurgy, and avoids the emission of arsenic-containing soot in the traditional process. The recovered gold-rich residue contains almost no base metals such as lead, bismuth, antimony, and arsenic. After subjecting the gold-rich residue to leaching gold by chlorination and reduction, a gold powder could be obtained therefrom with a lower content of base metals than traditional processes. Therefore, the method greatly reduces the amount of produced slag, shortens the production cycle, and reduces the loss of precious metals in the slag.Type: ApplicationFiled: October 12, 2022Publication date: August 29, 2024Inventors: Bin YANG, Baoqiang XU, Wenlong JIANG, Juhai DENG, Dachun LIU, Yang TIAN, Yifu LI, Lingxin KONG, Jia YANG

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
