СПОСОБ ЭЛЕКТРОЛИТИЧЕСКОГО ПОЛУЧЕНИЯ АЛЮМИНИЯ ВЫСОКОЙ ЧИСТОТЫ С ИСПОЛЬЗОВАНИЕМ ИНЕРТНЫХ АНОДОВ

摘要

A method of producing commercial purity aluminum in an electrolytic reduction cell comprising inert anodes is disclosed. The method produces aluminum having acceptable levels of Fe, Cu and Ni impurities. The inert anodes used in the process preferably comprise a cermet material comprising ceramic oxide phase portions and metal phase portions.
