Commercial extraction of metals from minerals is usually practiced by dump leaching, heap leaching, tank leaching, or pressurized leaching. Dump leaching is performed by percolating a leaching solution through mined ore that contains low concentrations (low grade) of desired elements.
Metals can be extracted from ores by reduction the removal of oxygen or forming a metal element from a compound.
Oxidation and reduction have multiple meanings, not just to do with the addition and removal of oxygen. Encourage students to use key terms as often as possible.
