Has a long history of iron-ore production, dating back (~1100 ad) to the in total , iron-ore deposits in the labrador sector of the labrador trough have produced in excess of 2 billion tonnes of iron ore the iron-ore mines of western labrador are currently the largest such ores require minimal beneficiation and have very. Direct reduction, in which iron ores are reduced at temperatures below the metal's melting point, had its origin in such experiments as the wiberg-soderfors process introduced in sweden in 1952 and the hyl process introduced in mexico in 1957 few of these techniques survived, and those that did were extensively.
