Manganese Ore In Bof Process

Dissolution behaviour of manganese ore in basic oxygen ...

In order to improve manganese yield during the reduction process of manganese ore in blowing practices employing less slag at BOF, the dissolution behaviour of manganese ore in slag has been studied in an experimental scale. The effect of temperature, slag composition, addition of CaF2, and pre-treatment of manganese ore was examined for the dissolution behaviour of manganese ore into BOF

PROPERTIES OF MANGANESE ORES AND THEIR CHANGE IN THE ...

In the process of calcination of manganese ores in air, MnO2 was reduced to Mn2O3 and Mn3O4, while during calcination in a reducing atmosphere manganese oxides were reduced to MnO and iron oxides to metallic iron. Formation of a liquid slag in ores at equilibrium was predicted for Wessels, Groote Eylandt and Gabonese ores at 1200°C in air and 1000-1200°C in a reducing atmosphere. No liquid slag was

Manganese - Wikipedia

A more progressive extraction process involves directly reducing manganese ore in a heap leach. This is done by percolating natural gas through the bottom of the heap; the natural gas provides the heat (needs to be at least 850 °C) and the reducing agent (carbon monoxide). This reduces all of the manganese ore to manganese oxide (MnO), which is a leachable form. The ore then travels through

Hydrometallurgical Processing of Manganese Ores: A Review

The production of manganese alloy from manganese ore is an energy intensive process and therefore, apart from manganese ore, power plays an important role in the production of ese alloy. There are basically two mangan processes for the manufacturing of the alloy using either one of high, medium or low grade ore, viz; Blast fur-nace and submerged electric arc furnace [SEAF]. When manganese ore

Thermodynamic properties of manganese oxide in BOF

It is necessary to understand the thermodynamic properties of MnO in steelmaking slags for the smelting reduction of Mn ore in BOF process. Studies of the manganese distribution between CaO-SiO 2-Fe t O-MnO slags and liquid silver in equilibrium with solid Fe in the temperature range of 1 623 to 1 723 K were carried out under a CO/CO 2 atmosphere. The Fe t O content in (32.4∼36.3)%CaO-(31.6 ...

19/09/2013  The industrial application of manganese ore in the conventional BOF process was researched and described by Brazilian and Chinese scientists [1, 2]. It was found that the final content of Mn in steel can be increased by 0.03–0.04 % using the addition of 10 kg of Mn ore per a ton of steel in the converter. Early charge of manganese ore and decreased volume of slag lead to the increase of
