Heavy non-ferrous metals
ArticleName Selective extraction of copper during hydrocarbonylation of sulphate-chloride solutions of non-ferrous metals
ArticleAuthor Fedoseev I. V., Maksimov V. V.
The paper shows that combination of hydrocarbonylation process, leading to removing of ~95% of copper from solution, with finishing operation by the way of solution processing with copper powder allows to remove copper technologically completely from solutions, contained Fe, Ni, Co and other heavy non-ferrous metals. Copper extracted from solutions conform to M0 grade in its level of restricting impurities.
