Iron ore - Wikipedia

Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil ".

Laboratory Studies on Phosphorus Removal from Nigeria s ...

The iron ore, Plate 2.1, was collected from Agbaja, an indigenous community near Lokoja, Kogi State of Nigeria. Standard glass wares, heavy equipment, chemicals and disposables used in the phosphorus removal process were sourced locally. Plate 2.1 Agbaja iron ore 1kg of the iron ore was manually crushed in the laboratory using hammer and anvil to

Phosphorus Removal Capability of Aspergillus Terreus and ...

Comparative phosphorus removal capability of a microbial fungus-Aspergillus terreus and a bacterium-Bacillus subtilis from Nigeria’s Agbaja iron ore was investigated. Manual crushing and sieving of the iron ore in Shital Test Kits produced 5 stone size distributions namely:
