of lead, copper, silver, antimony, iron and other metals[1-2]. On one hand, there are about several hundred thousands tons of arsenic cycling in the steps of mining, beneficiation and smelting each...[6-7]. Therefore, how to effectively dispose and use arsenic compounds is a hot potato for many smelting plants[8-10]. In 18th century, the Sweden chemist Scheele firstly discovered copper arsenite......
electrolysis of 13 d. The appearances of cathode copper obtained at 235 and 305 A/m2 are slippery and even, and the qualification rate is 100% according to the Chinese standard of high-pure cathode copper..., with the rapid development of copper smelting industry, the competition of raw material gets fiercer in China, which induces the increase of impurities in raw material. The impurities of Sb and Bi cannot......
