The quality of the product, the iron concentrate, varies widely from low for direct relatively shipping ores (55-69 wt.% Fe) to very high for operations producing pellets and other special products (65-70 wt.% Fe). Iron ore mines and their processing plants traditionally use chemical analysis in grade and product quality control.

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 ...

2021-2-21 Iron ore mining often focuses on looking for hematite deposits known as red iron ore, and magnetite, as they have naturally weak magnetic fields that aid in their purification. Hematite, however, responds better to the flotation process in iron ore beneficiation than magnetite, so it is the preferred type of ore.
