Abstract
Impurity removal from Cu-Zn (brass) alloy is an important issue for copper feedstock production. This study investigated brass alloy purification through the slag refining process using two kinds of agents, namely Cu2O and ZnO. The results showed that using ZnO as the slag to purify brass alloy for 1 h can remove impurities, such as Al, Pb, Fe, Ca, and Si, among which the removal efficiencies of Si reached to 60%. After the ZnO slag refining, the Zn loss ratio was only approximately 2%; thus, the brass alloy composition remained stable. The slag refining process using ZnO-contained slag did not only realize brass purification, but also maintained the brass composition stability.
