Blast Furnace Charge (Raw Materials for Steel-making ...

Jan 11, 2013· 1. QUALITY OF CHARGE MATERIAL: A blast furnace charge consists of coke, ore or sinter, and limestone. These materials must be in lumps of a certain size (40-60 mm). Larger lumps prolong the process of reduction and fluxing. Smaller lumps block the flue-gas passages and prevent a uniform descent of melting materials in the furnace. 2. IRON ORES: Ore is a metal bearing mineral.

Extraction of Manganese -

Extraction of Manganese. Prior to the use of electric arc furnace, ferromanganese was produced in mini blast furnace. But the composition was not controlled properly in the blast furnace. High grade ferroalloys are produced by adjustment the composition in the blast furnace.

Blast-furnace. Operation of blast furnace. - Metallurgy.

The products of the blast furnace are pig iron (hot metal) and slag from the lower part of the furnace and flue dust and blast furnace gas from the top. Prepared raw materials for blast furnace namely sinter, iron ore lump, coke and additives like manganese ore, quartzite, limestone.

The Extraction of Iron - Chemistry LibreTexts

The air blown into the bottom of the furnace is heated using the hot waste gases from the top. Heat energy is valuable, and it is important not to waste any. The coke (essentially impure carbon) burns in the blast of hot air to form carbon dioxide - a strongly exothermic reaction. This reaction is the main source of heat in the furnace.


HOW A BLAST FURNACE WORKS Introduction The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.

Recover Manganese – Fluosilicic Acid Leaching

The effect of agitation rate on manganese extraction was studied using slag samples of minus 100 mesh size. A pulp density of 9.9 pct, an acid content of 0.94 g of H2SiF6 per gram of slag, a temperature of 95° C, and a leaching period of 5 h were used. Under these conditions, 693 pct of the manganese was extracted at an agitation rate of 160 rpm.

An efficient utilization of high chromium vanadium slag ...

Vanadium slag as the product after blast furnace ironmaking and vanadium oxidation in converter with vanadium-bearing titanomagnetite, is a main material for vanadium extraction [,, ]. With the large-scale utilization of the normal vanadium-bearing titanomagnetite with low chromium content, its reserves are decreasing every year.

Manganese - Wikipedia

Manganese is a chemical element with the symbol Mn and atomic number 25. It is not found as a free element in nature; it is often found in minerals in combination with iron. Manganese is a transition metal with important industrial alloy uses, particularly in stainless steels.

Hydrometallurgical Processing of Manganese Ores: A Review

extraction of manganese from ores and waste materials were discussed. Keywords ... Blast fur-nace and submerged electric arc furnace [SEAF]. When manganese ore is converted into manganese alloy, there is a loss of about 15% of manganese as slag. The remaining 85% of manganese alloy is further divided and used

Smelting manganese ore - Royster, Percy H.

Another object of invention is the provision of an improved blast furnace process of smelting low manganese-high silica ores (or metallurgical equivalents), which improved process involves the consumption of relatively small amounts of solid fuel (e. g., materially less fuel than ore, by weight).

Manganese processing |

Extraction and refining. Pure manganese is produced by hydrometallurgical and electrolytic processes, while ferromanganese and silicomanganese are produced by the smelting of ores in a blast furnace or, more commonly, in an electric furnace. The latter process, involving the reduction of manganese oxides by carbon, is actually a complex ...
