![[VIDEO] HowTo: Turn Iron Ore into Steel | Mining Digital](/rnudpye/120.jpg)
The first stage of turning iron ore into steel is the processing. The rock is first grounded up with the ore being extracted using magnetic rollers. The finegrained ore is then processed into coarsegrained clumps, which is used in the blast furnace. According to ArcelorMittal, one of the largest steel and mining companies, a mixture of iron ...

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.

The net import of iron ore was billion tons, and the iron content of imported iron ore was 660 million tons. Iron ore from Australia, Brazil, and other places was the main body of China's iron metal import trade, accounting for more than 90% of total iron metal imports. This is because most of China's iron ores are lean and deeply buried.
