processing, use of a smelting to turn the into a form from which products can be fashioned.Included in this article also is a discussion of the mining and of its preparation for smelting. Fe is a relatively dense metal with a silvery white appearance and distinctive magnetic properties. It constitutes 5 percent by weight of the Earth’s crust, and it is the

· was won by drilling and blasting .As mining technology generally developed, so did drilling techniques and the explosives used. Smith 1990 reported that the Cleveland deposit was associated with a very strong stone roof rock known as “dogger” allowing mine drivages to be self-supporting. However, he states that in later years where the mining had progressed to the dip, this

· Perhaps the best illustration of this slow progress has been the history of the process, promoted by its proprietor as “the world’s first commercial direct smelting process for making iron straight from the ore” Rio Tinto, 2014. Its history goes back to the development of bottom-blown oxygen converters and combined steelmaking by Klöckner Werke in the early 1970s
