摘要

:在这项工作中，研究了电渗析（ED）和电解电渗析（EED）技术，以从铜锍矿物的火法冶金加工和低铜含量混合矿物的湿法冶金处理过程中产生的废物和废液中回收锑。这项工作的挑战在于应用电化学方法回收这些有价值的材料，并循环利用电解法后期分离阶段使用的高浓度酸溶液。对溶液进行了电化学表征，并在电化学电池中进行了锑和铋的电沉积。此外，还研究了在回收此类材料时采用膜工艺的问题。

Application of the Electro-Electrodialysis Technology in the Copper Mineral Processing Industry: Recovery of Antimony from Mining Tailings and Recycling of the Regenerated Solution Media

: In this work, electrodialysis (ED) and electro-electrodialysis (EED) were investigated as technologies for the recovery of Sb from wastes and efﬂuents generated during the pyrometallurgical processing of copper sulﬁde minerals and the hydrometallurgical treatment of low-copper-content mixed minerals. This work addresses the challenge of applying electrochemical methods for recovering these valuable materials and recycling highly concentrated acid solutions used in the latter separation stages of the electroreﬁning process. The electrochemical characterization of the solutions was conducted, and the electrodeposition of Sb and Bi was performed in electrochemical cells. Also, the implementation of membrane processes in the recovery of such materials was investigated.
