Details >Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron oxide. The oxygen must be removed from the iron oxide to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions.
Details >Process. In the blast furnace process, the first step on the way towards heavy plate, pig is produced from . The composition of the and additions is accurately adjusted to the final products of AG der Dillinger Hüttenwerke and Saarstahl AG.
Details >The of ores involves three stages – concentration, calcination and reduction. Haematite is concentrated by hydraulic washing or gravity separation, while magnetite is concentrated by magnetic separation. The concentrated is then subjected to calcination. Calcination:
