The usual characterization of the intrinsic quality of iron ore fines and lumps in the metallurgical industries has been based only on chemical analysis and granulometry. A lot of typological categories of iron ores and different ore blends can be used in the industrial processes of agglomeration and reduction.

INCREASING portions of the iron ores extracted from the mines are submitted to agglomeration - processes such as sintering and pelletising prior to their smelting in the blast furnace. These processes have been developed in order to agglomerate iron-containing fines such as the portion of fine ore, fine grained concentrates obtained …

The Chapter covers a brief description on the iron-making processes and their correlations with the quality parameters of ferruginous burden materials: iron ore in lump form and agglomerates in the form of sinter and pellets. The integrated blast furnace and oxygen steel-making route happens to be a dominant process for steel production worldwide.

· In this study, a process to separate manganese and iron from manganiferous iron ores by reductive acid leaching followed by magnetic separation was conceived and experimentally tested. In the leaching process, sulfuric acid was used as lixiviant and oxalic acid was used as reductant. The experimental results showed that the manganese and …

Solar thermal processing of iron ores The process of steel making from iron ores involves three main pyrometallurgical stages: (1) agglomeration processes of iron ore fines such as pelletisation and sintering, (2) reduction of iron ores to produce solid or liquid iron and (3) purification of iron and alloy addition to produce steel.

· The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. However, most of these ores do not respond well to the conventional …
