Taconite is a lowgrade iron ore. When the highgrade natural iron ore was plentiful, taconite was considered a waste rock and not used. But as the supply of highgrade natural ore decreased, industry began to view taconite as a resource.
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. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale.
Iron ore is the source of primary iron for the world''s iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. Almost all (98%) iron ore is used in steelmaking. Iron ore is mined in about 50 countries.

The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items. It is the mostused metal by both tonnage and purpose.
The business of mining iron ore is a high volume, low margin industry because of the low value of iron. The transport of iron ore by way of railway or freight requires a highly stable infrastructure for the mining production to be economically feasible. As a result, the mining of iron ore has remained in the control of a few major companies.
While Britain had good iron ore reserves, the iron produced was of low quality with plenty of impurities, limiting its use. There was plenty of demand but not much was produced as wrought iron, which had many of the impurities hammered out, took a long time to make, and was available in cheaper imports from Scandinavia.
