Iron Ore Mining Techniques Metal Extraction

2021-7-15  Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. This slag can be used in road making and as "slag cement" a final ground slag which can be used in cement, often mixed with Portland cement.

WHERE IS IRON ORE MINED?

2021-1-21  To be economically viable for mining, iron ore must contain at least 20% iron. Magnetite ore has the highest proportion of iron, at 65%. Haematite ore also has a high content of iron at 60%. All iron ore contains ferric oxide and it is from this that iron is extracted. Approximately two billion tonnes of iron ore are mined each year.
