hematite iron ore processing

Introduction. The production of iron from its ore involves a redox reaction carried out in a blast furnace. The furnace is filled at the top with the iron ore oxide most commonly hematite ((Fe_2O_3)) but can also magnetite ((Fe_3O_4)), carbon called coke and limestone ((CaCO_3)).

The Purification Of Iron From Its Ore

Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe 2 O 3 and is widespread in rocks and soils. Hematite forms in the shape of crystals through the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).

Extraction of Iron & Concentration of Ore

The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag. What happens in the Blast Furnace? The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal state.

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.

Purification Of Iron Ore In A Blast Furnace

The most common ore of iron is called haematite (iron(iii) oxide). Its formula is Fe 2 O 3. Haematite is added to the top of the furnace along with coke (i.e. carbon) and limestone. Three reactions take place during this extraction. Firstly, the carbon in the blast furnace burns with the hot air to form carbon dioxide. This reaction

Why is hematite used over magnetite? Magnetite has more ...

Iron is the 4th most abundant element in the Earth's crust and it exists mostly as an oxide because it is easily oxidized in air. Iron has 16 oxides and among these, hematite is the oldest known. Hematite is a red-brown solid that is extremely stable under ambient conditions. It is often the end-product of all other iron oxide transformations.
