    201511ensp;0183;ensp;Iron ore 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 selfsupporting. However, he states that in later years where the mining had progressed to the dip, this

    The majority of steel production is supported by iron ore sourced from highgrade hematite deposits, although a significant fraction comes from magnetite deposits. Compared to direct shipping hematite ores mined from the upper regolith, magnetite deposits require significant beneficiation, which typically involves grinding to a particle size where magnetite is liberated from its silicate matrix.

    Hydrogen can serve as a reducing agent and the most prominent application appears to to be iron ore reduction. A variety of direct reduction of iron ores without coke has been carefully studied for a long time. These use hydrogen, carbonmonoxide and carbon in a combination. The reason for the development is due to the following (1)
