An enrichment technology for reduced siderite ore has been developed for the production of concentrate that may be used in steel smelting. The technology includes dry and wet magnetic separation. Conditioned briquets may be produced from reduced siderite-ore concentrate and used in arc furnaces as a partial or complete replacement for scrap or hot metal. © 2011 Allerton Press, Inc.

A pyrometallurgical enrichment technology for siderite ore has been developed. By means of an inexpensive and environmentally benign technology for X-ray separation, a high-quality enriched product may be obtained. Analysis of options for producing reduced ore permits the identification of a thermal-reduction technology that is the most promising and is also relatively inexpensive. Once implemented, this approach will permit the processing of siderite ore at a rate of 2. 5 million t/yr and the production of sponge iron in quantities of around 0. 5 million t/yr after modernization of the mining and enrichment system within OAO Bakal'skoe Rudoupravlenie, without the need for the preliminary manufacture of oxidized pellets or the construction of expensive smelters. © 2010 Allerton Press, Inc.

The reduction of zinc and iron oxides from blast-furnace slurry and gas-purification dust at steel furnaces by heating with carbon is studied in physicochemical terms. Kinetic analysis reveals the optimal parameters of furnace reduction. Initial data are obtained for the development of a reduction technology for zinc and iron oxides. © 2013 Allerton Press, Inc.
