Abstract

Language:

Specifications on impurity levels in metals are becoming more stringent, prompting a need for improved refining technologies. This study explores electrochemical refining as a means to selectively remove noble elements like copper from active host metals such as lead, iron, and aluminium using solid electrolytes. Despite several studies on solid electrolytes in concentration sensors, their application in metal refining remains limited, particularly regarding the removal of noble elements. The behavior of these electrolytes under the extreme conditions of molten metal refining is not well understood. This paper investigates the potential of solid electrolytes in the removal of copper from iron and assesses the suitability and selection criteria of these materials for future industrial applications. In particular, the stability of Cusicon, a copper superionic conductor, is evaluated through experimental results, demonstrating its potential for enhancing metal refining processes. This research aims to offer insights into innovative refining techniques that could address the challenges posed by increasingly strict impurity specifications.
