Iron Ore Extraction Blast Furnace

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.

How do we extract iron from its mineral ores? How do we convert it into steel? The raw materials needed i.e. limestone, coke, air and iron ore and the chemistry of the blast furnace are fully described.

Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities.

The process of the extraction of iron is carried out by the following steps: Concentration of ore Calcination or Roasting of ore Reduction of ore

This page looks at the use of the Blast Furnace in the extraction of iron from iron ore, and the conversion of the raw iron from the furnace into various kinds of steel.

Blast furnace: Blast furnace, a vertical shaft furnace that produces liquid metals by the reaction of a flow of air introduced under pressure into the bottom of the furnace with a mixture of metallic ore, coke, and flux fed into the top.

Extraction of Metals. Extraction of Iron.. Iron is extracted from its ore in the blast furnace.. The main iron ore is called haematite. Haematite is iron(III) oxide - Fe 2 O 3. The iron ore contains impurities, mainly silica (silicon dioxide).

then reacts with the iron ore to form carbon dioxide and pure iron. Separating the iron from the slag 2 The melted iron sinks to the bottom of the furnace.

How to extract iron from its ore The method Three substances are needed to enable to extraction of iron from its ore. The combined mixture is called the charge: Iron ore, haematite - often contains sand with iron oxide, Fe2O3.

1. Introduction to the extraction of metals. What methods can be used in extracting metals from mineral ores? The Earth's crust contains many different rocks.. Rocks are a mixture of minerals and from some we can make useful substances.

Mining of Iron Ores. Iron ore is a type of mineral and rock from which metallic iron is extracted economically. This ore is normally rich in iron oxides and vary in color from dark grey, bright yellow and deep purple to rusty red.

3. The three raw materials added to the top of the blast furnace are a) Iron ore, coke and slag

and has replaced charcoal as a reducing agent. Up to the close of 1902, Michigan had produced 4,178,218 tons of charcoal pig iron. Of this 1,882,274

As already mentioned only a few most unreactive metals occur in nature in free state. Most of the metals occur in nature in oxidized form as their compounds.

The process. The concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate and air or oxygen in a furnace or series of furnaces.
