Iron ore mining in Western Australia Wikipedia

Up until the mid-1960s, iron ore production in Western Australia, and Australia as a whole, was negligible, in the range of less than 10 million tons a year. By the mid-1970s, this figure had reached 100 million tonnes, with the majority coming from Western Australia.

Function Of Iron Learn About The Role Of Iron In Plants

Iron for plants can come from a number of sources. Ferric oxide is a chemical present in soil that gives dirt a distinctive red color, and plants can absorb iron from this chemical. Iron is also present in decomposing plant matter, so adding compost to your soil or even allowing dead leaves to collect on the surface can help to add iron to your plants' diet.

Blast furnace metallurgy Britannica

Blast furnace. The iron oxides in the ore are chemically reduced to molten iron by carbon and carbon monoxide from the coke. The slag formed consists of the limestone flux, ash from the coke, and substances formed by the reaction of impurities in the ore with the flux; it floats in a molten state on the top of the molten iron.
