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 Cu2 O 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.

炉渣精炼法去除黄铜合金杂质

铜锌(黄铜)合金中杂质的去除是铜原料生产中的一个重要问题。本研究采用氧化铜和氧化锌两种助剂对铜合金进行渣精炼工艺提纯。结果表明，以ZnO为渣净化黄铜合金1 h，可以去除Al、Pb、Fe、Ca、Si等杂质，其中Si的去除率达到60%。ZnO渣精炼后，锌损失率仅为2%左右;因此，黄铜合金成分保持稳定。采用含锌炉渣精炼工艺，既实现了黄铜的提纯，又保持了黄铜成分的稳定。

期刊介绍： Metallurgical Research and Technology (MRT) is a peer-reviewed bi-monthly journal publishing original high-quality research papers in areas ranging from process metallurgy to metal product properties and applications of ferrous and non-ferrous metals and alloys, including light-metals. It covers also the materials involved in the metal processing as ores, refractories and slags. The journal is listed in the citation index Web of Science and has an Impact Factor. It is highly concerned by the technological innovation as a support of the metallurgical industry at a time when it has to tackle severe challenges like energy, raw materials, sustainability, environment... Strengthening and enhancing the dialogue between science and industry is at the heart of the scope of MRT. This is why it welcomes manuscripts focusing on industrial practice, as well as basic metallurgical knowledge or review articles.
