The production of iron from its ore involves an oxidationreduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron must be first ...

Iron ore sintering is one of the key steps in the ironmaking process, where granulated pellets are transformed into sinter in the sintering machine, providing an ideal raw material for ironmaking blast furnace. Drum granulation in the sintering process plays an essential role in determining the final sintering performance.

Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, through to deep purple, rusty red and bright yellow.

Mucking was host to a small iron smelting industry because of its workable deposits of iron ore. [4] Spongy iron blooms were produced and had their impurities worked out by a process known as 'Mucking'. [5] It is not known if this process is connected to the village name or a coincidence. Modern Mucking

Mucking of the ore is done with a scooptram, immediately after the blast of a row. For this reason, the majority of the mucking is done remotely. The ore is brought from the stope to an orepass located in the access drift. To limit dilution caused by mucking on rock fill, a line is painted on the walls. This method is simple and gives the ...
