Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue". The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out ...
The making of cast iron begins with a combination of raw materials. Iron is rarely found in its pure form. Only meteorites contain pure iron. The iron in use for centuries is found in the combination of iron and other elements. These combinations are known as iron oxides. Mining pulls most of the iron from iron ores ...
This has eventuated because of the nature of the ore mined locally and used in the process. Early pioneering experiments failed to successfully smelt iron from New Zealand's west coast ironsand deposits because the magnetite ore (Fe 3 O 4 ), as it is known, is locked in with minerals such as titania and silica.
A blast furnace is a special type of furnace for smelting iron from ore.Blast furnaces are very large. They can be up to 60 metres (200 ft) tall and 15 metres (49 ft) in diameter.The blast furnace is the biggest chemical reactor..

2017/01/20· Mining iron ore begins at ground level. Taconite is identified by diamond drilling core samples on a grid hundreds of feet into the earth. Taconite rock comprises about 28 percent iron; the rest is sand or silica. These
2017/03/07· Iron Smelting is the process of making iron ore into iron. The smelters heat up the iron ore to melting point using charcoal as fuel. They then cast the heated iron ore into ingots called pigs. The ingots were either reheated and cast
2017/10/10· Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off …
2019/06/05· Cast iron has already been mentioned above. This section deals with the types of iron and steel which are produced as a result of the steel-making process. Wrought iron: If all the carbon is removed from the iron to give high purity
2020/05/17· Iron making 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 …
The iron ore shown to the right was excavated from Skógar, a Viking-age iron-making site in Iceland. The larger piece is about 2cm (less than 1in) in the long dimension. Sometime about 1000 years ago, someone gathered this iron ...

Ancient iron production refers to iron working in times from prehistory to the early Middle Ages where knowledge of production processes is derived from archaeological investigation. Slag, the byproduct of iron-working processes such as smelting or smithing, is left at the iron-working site rather than being moved away with the product.
2019/06/13· Bloomery forges are the oldest form of smelting iron first used thousands of years ago. In early to mid 2019 a group of volunteers at The Crucible in Oakland, California did a series …
