· The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes …

· The most important ore veins of the metamorphic-hydrothermal siderite-sulfidic mineralization were the Hrubá and Zlatá veins, which were 16 and 24 km long, respectively, making them the longest ore vein structures in the Spišsko-Gemerské Rudohorie Mts. (Grecula et al. 1995). The veins are characterized by continuous mineralization over a ...

· The Kremikovci deposit of siderite ore is localized at 15 km NE from Sofia town (Bulgaria). The running characteristics of siderite ores are investigated by complex methods of research. The siderite ore mineral composition dominates by siderite, barite and quartz. Microscopic polished sections have been studied to assess the size of liberation.

· Abstract This paper shows that the existing siderite ore preparation techniques do not allow achieving high blast-furnace smelting levels as compared with using black iron ore concentrates with a high iron content. To make blast-furnace smelting more efficient, it is necessary to use the metallized product made by regenerative siderite ore roasting. The …

It was determined that the current method of the Bakalsk mining department siderite ore preparation for blast-furnace smelting does not allow production of concentrate meeting the state-of-the-art metallurgy requirements. The most perspective method is reducing firing when a metallized product with higher iron content is obtained. It was demonstrated that …
