Экспериментально установлено, что в колоколообразных устройствах при температуре 1100 °С основная масса железа отвального шлака сульфидной плавки медных концентратов может быть восстановлена до металла продуктами газификации углерода. Последующее повышение температуры до 1200 °С позволяет увеличить извлечение железа. При косвенном восстановлении шлака при температуре выше температуры его плавления металлическое железо концентрируется, в основном, на внешней поверхности продукта восстановления, образуя крупные включения, которые легко извлекаются магнитной сепарацией. Наиболее целесообразно восстанавливать многослойную шихту из слоев шлака толщиной менее5 мми разделяющего их молотого угля. </p></abstract><trans-abstract xml:lang="en"><p>The authors discuss the investigation results of phase transformations in the slag of sulphuric cupreous melting during its reduction by the products of gasification of carbon at the temperatures 1100 and 1200 °С. It was experimentally found, that in belllike equipment at the temperature 1100 °С the most part of iron from dump slag of sulphuric melting of the cupreous concentrates may be reduced to metallic state by the products of carbon gasification. Subsequent rise of temperature up to1200 °Cenables to increase iron recovery. During the indirect reduction of the slag at the temperature above temperature of its melting, metallic iron concentrates mostly at the external surface of product of reduction, producing large inclusions, which may be easy extracted by magnetic separation. It’s mostly rational to reduce multilayer blend, consisting from slag layers with the thickness less than5 mmand separating them layers of grinded coal. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>шлак сульфидной медной плавки</kwd><kwd>фаялит</kwd><kwd>условия восстановления железа</kwd><kwd>фазовые превращения</kwd><kwd>извлечение железа из шлака</kwd><kwd>восстановление продуктами газификации углерода</kwd><kwd>влияние температуры</kwd><kwd>магнитная сепарация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>slag of sulphuric cupreous melting</kwd><kwd>fayalit</kwd><kwd>conditions of iron reduction process</kwd><kwd>phase transformations</kwd><kwd>recovery of iron from slag</kwd><kwd>reduction by the products of carbon gasification</kwd><kwd>temperature effect</kwd><kwd>magnetic separation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Gorai Bipra, Jana R.K., Premchand.
