A Green Anodic Electrolysis Strategy for Recovering Copper and Selenium From Cuprous Selenide
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Selenium, a rare strategic metal, is essential for advanced technologies and biological systems. Cuprous selenide (Cu2Se), a selenium‐rich compound found in copper anode slime and a promising thermoelectric material, holds great potential for recovery.

Shuitu Baochi Xuebao, 2006 棕壤对铜的吸附特性以及土壤条件对吸附的影响进行了研究，结果表明，棕壤对铜的吸附随溶液中铜的平衡浓度增加而增加，但在高浓度时增幅渐缓，与处于相同地区的褐土相比棕壤的吸附相对较弱，其吸附可用Langmiur、Frundlich、Temkin及米氏方程进行描述。土壤酸度增强，棕壤对铜的吸附降低，用H^＋浓度对Frundlich方程进行修饰，能更好地描述铜的吸附状况。此外，离子强度、陪伴离子对吸附都有影响，随离子强度增加及高价陪伴离子比例的上升吸附减弱。
