Common methods of extracting the iron ore consist of blasting, drilling, or general excavating,,. Most iron ore is produced from open-pit mines. After the iron ore is out of the ground, it may be shipped to the iron and steel manufacturing plant. If the ore contains less than 60 percent iron, it is usually beneficiated to an iron .
Reduction with carbon []. Iron is extracted from its ore, haematite, by reduction with carbon. This takes place in a blast furnace (named after blasts of air [20% oxygen], heated to 1000 °C, which are blasted into the bottom of the furnace):
Sep 04, 2012· The extraction of Iron and its impact on the environment GENERAL OVERVIEW. ... Impacts on the environment due to the extraction of iron from haematite does not only start during the extraction of iron from the ore - it starts when the raw materials are being mined and transported. The following are problems which arise from these processes:
103 Extraction of metals | Accelerated Study Notes. 08/01/2012 · P1 Describe the use of carbon in the extraction of some metals from their ores In case of iron, the oxides are reduced by reaction with Carbon and/or Carbon Monoxide P2 Describe the essential reactions in the extraction of iron in the blast furnace Coke (Carbon), Haematite (Iron II Oxide), and Limestone (Calcium Carbonate) is needed
Extraction of Iron from Haematite. Step 1: The Iron ore is crushed and broken into smaller pieces, concentrated with gravity separation process (washed with water). Step 2: The raw materials are added into the top of the furnace : Iron ore (Haematite, Fe2O3), Coke (Carbon, C), Limestone (CaCO3)
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). Limestone (calcium carbonate) is added to the iron ore which reacts with the silica to form molten calcium silicate in the blast furnace.
EXTRACTION OF IRON INTRODUCTION Iron is extracted from its ore called HAEMATITE (Fe2O3). oxide PRINCIPLE OF EXTRACTION Extraction of iron is based on the reduction of HAEMATITE (Fe2O3) with carbon.. DETAILS OF EXTRACTION The process of the extraction of iron is carried out by the following steps: Concentration of ore Calcination or Roasting of ...
EXTRACTION OF IRON IN A BLAST FURNACE Iron is also below carbon in the reactivity series, so therefore carbon can be used to reduce it (note: reduction can also mean to remove the oxygen from a compound). This is done in a blast furnace.

Extraction of Iron: Iron is extracted from its chief ore Haematite Fe 2 O 3.The various steps involved in the process are as follows: 1. Crushing: The ores are crushed in jaw crusher and powdered in ball mills. 2. Concentration: The crushed ore is washed with steam or cold water to remove clay and sand. The washed ore is then concentrated by electromagnetic separation process.
Hematite, also spelled haematite, heavy and relatively hard oxide mineral, ferric oxide (Fe 2 O 3), that constitutes the most important iron ore because of its high iron content (70 percent) and its abundance. Its name is derived from the Greek word for "blood," in allusion to its red colour. Many of the various forms of hematite have separate names. The steel-gray crystals and coarse ...
