2015-1-1  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 self-supporting. However, he states that in later years where the mining had progressed to the dip, this ...

A method of upgrading relatively rich, fine-grained earthy hematite iron ores is provided. The iron ore, after suitable preparation, is reduced using a solid state reduction technique. As a result of the reduction process, the iron grains undergo size enhancement while the nonmetallic oxides are unreduced and remain as refractory oxide gangue.

2015-8-17  By sintering, the pelletisation of fine-grained, smeltable ores, iron ore in particular, to compact lumps by heating nearly to the melting or softening point is understood. Melting tendencies at the grain boundaries lead to a caking of the material. Before the sintering, the various substances are first mixed and, if desired, granulated.
