Apr 25, 2017· Mining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil. Mining can also trigger the formation of sinkholes. The leakage of chemicals from mining sites can also have detrimental effects on the health of the population living at or around the mining site.
Nevertheless, iron ore production value is well up from its recent low in 2015, and despite recent downturns in iron ore price, WA has seen an average yearonyear increase since the start of the iron ore boom in 2002 of per cent in the quantity of iron ore sold and per cent in its value.
The effects of selecting an appropriate iron ore are relevant when the ore is reduced in a blast furnace. Although hematite possesses a higher ratio of oxygen (O/Fe = ) than does magnetite (O/Fe = ), hematite is more easily reducible than magnetite because magnetite is crystalline (is less reactive and displays a lower ability to reduce ...
