Iron Ore Electrolysis
Actually the extraction of a metal from its its ore depends upon the selection of a proper reducing agentiron is a moderately active metal and its oxides can be reduced using carbon and not by using electrolysis on the basis of energy.
Very high zinc extraction rates (up to 99%) from low-grade ores (as low as only 5% zinc) can also be achieved using bacterial action. The bacteria used thrive at temperatures up to ca 320 K, and produce weak zinc solutions that are concentrated for electrolysis using solvent extraction.
