Nov 102017 1. Introduction. Hematite (-Fe 2 O 3) is widely distributed in various rocks and is one of the most common and abundant iron oxide minerals in soil (Zhang2007).Howeverit cannot be used in iron and steel industry without preliminary beneficiation due to its low grade. Many researchers have investigated the separation of iron minerals from gangue minerals by froth flotation process (Luo et
Iron is extracted from its orehaematite in a blast furnace. The ore is led into the top of the furnace along with coke and limestone. The limestone decomposes in the hot furnaceforming calcium oxide. This reacts with the sandy impurities (silicon dioxide) to form a slag.

Jan 042016 That makes the iron extraction process much less costly and time consuming. In additionhematite ore only goes through one stage of screening and crushingwhile magnetite ore has an additional round of processing. Types of iron ore: Magnetite. With the chemical formula Fe3O4magnetite ore has much lower iron content than hematite ore.
The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.
