This ore type requires extensive grinding to separate the iron from the silica and other impurities The fine particle size of the resulting iron ore concentrate is better suited to pelletising than sintering which is why almost all US iron ore is pelletised

How Is Iron Extracted From the Earth

Iron ores in the form of hematite ferrous oxide and magnetite are removed from the earth through mining The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore however because iron does not occur naturally it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore

Gold extraction Wikipedia

Gold extraction refers to the processes required to extract gold from its may require a combination of comminution mineral processing hydrometallurgical and pyrometallurgical processes to be performed on the Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing resulting in direct recovery of
