Roasting is the process of heating iron ore strongly in dry air for drying the ore and expelling humidity, It is used to increase the percentage of iron in the ore and for the oxidation of some impurities such as sulphur and phosphorus.. Roasting of iron is very important in the ore dressing process but this process

iron processing Iron making Britannica
The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way. A third group of iron-making techniques classed as smelting

THE BLAST FURNACE IRON PRODUCTION
2021-1-21 As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron. The stock level is constantly ‘topped up’. Molten iron ore is ‘tapped’ at the bottom of the blast

How iron is made material, manufacture, making, history,
Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements. On the surface, the future of iron production—especially in the United States—appears troubled. Reserves
