Transformation of Selenium-Containing Phases in Copper Anode Slimes ...

2017年7月10日  The transformation of selenium-containing phases in copper anode slimes during the leaching process was investigated based on the Eh–pH diagram, leaching efficiencies of metals, and characterization of the residues produced during leaching. The leaching efficiency of selenium increases slowly to 17.7% in the first 50 min and then 2023年9月1日  Copper anode slimes often contain impurities, with varying levels of barium (Ba) depending on the ore source and refining process. Barium is commonly found in copper ores as barite, which can be removed during leaching. The refining process also removes impurities, including barium, which may end up in anode slime. ...From waste to wealth: Unlocking the value of copper anode slimes ...2017年8月12日  Based on the Eh–pH diagram for the Se–H 2 O system, a new method is proposed for leaching selenium from copper anode slimes using a nitric acid–sulfuric acid mixture.

Anode slimes - Palabora

Anode slimes is a by-product of the electro-refining process and consists of the insoluble impurities from the anode that fall to the bottom of the refining cell. The anode slimes are recovered from the refining cells, dried in an oven and processed by a metals by-product plant. The principle insoluble impurities are Silver (Ag), Arsenic (As ...4 天之前  王晖,wanghui,中南大学王晖，博士生导师王晖,Wang Hui 王晖，男，汉族，1968 年 2 月生，安徽太湖人，工学博士，中南大学教授，博士生导师，二次资源与环境污染控制研究所所长。 主要从事资源加工、环境化工等领域的研究与教学工作。主持和参加国家科技 ...中南大学 王晖
