Iron ore Wikipedia

Chilean magnetite iron ore deposits within the Atacama Desert have also formed alluvial accumulations of magnetite in streams leading from these volcanic formations. Some magnetite skarn and hydrothermal deposits have been worked in the past as highgrade iron ore deposits requiring little beneficiation.
