Iron ore - Wikipedia

  

2019-10-15  Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite. Iron-ore mining methods vary by the type of ore being mined.

Metallurgic Processes Boundless

Metal ores are formed in the process of ore genesis, and they are extracted through mining. Extractive metallurgy is the pract of removing valuable metals from an ore and refining the extracted raw metals into a purer form. Hydrometallurgy uses aqueous solutions to extract metals from ores ( leaching ).
