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 ...
There is no ore dust or direct ore exposure to the environment and a lower consumption of water is needed in the mining process (International Atomic Energy Agency [IAEA], 2005). However, the strong acids used to dissolve the ore body commonly dissolve metals in the host rock as well.
and silver are among the most wasteful metals, with more than 99 percent of ore extracted ending up as waste. By contrast, iron mining is less wasteful, with approximately 60 percent of the ore extracted processed as waste (Da Rosa, 1997; Sampat, 2003). Disposing of such large quantities of waste poses tremendous challenges for the mining
