with reduction behavior of iron ore sinter. Since the discovery of cohesive zone in quenched blast furnaces, many investigations have been explored to evalu-ate the behavior of sinter during reduction at high tempera-tures. Reduction behavior of sinter is determined namely by three factors, chemical composition, pore structure and mi-

The iron and manganese ores occur as distinct sedimentary layers alternating with iron and manganese-poor sedimentary layers - the whole mass is sometimes mined. Iron ores of this type are commonly termed the banded iron formation or simply abbreviated as BIF. All ore minerals in these deposits are oxides and hydroxides.

Current iron ore processing generates about 25% of very fine material called iron ore slimes. These slimes are being disposed into tailing ponds owing to their high alumina content (10–15% ...

Because the raw materials are carefully controlled to produce consistent crude iron, the range of slag chemical composition is fairly narrow for a specific ore and furnace operation. The hot air blast to the furnace burns the coke and maintains the very high temperatures that are needed to reduce the ore to iron.

quality of iron ore is chemical composition. The accurate classification of iron is of great significance to the acquisition of raw materials in the metallurgical industry.

Basalt is a very common dark-colored volcanic rock composed of calcic plagioclase (usually labradorite), clinopyroxene ( augite) and iron ore (titaniferous magnetite ). Basalt may also contain olivine, quartz, hornblende, nepheline, orthopyroxene, etc. Basalt is a volcanic equivalent of gabbro. Basalt is a fine-grained and dark-colored rock.

 · History . Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores.   The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.
