Iron ore is the IMPURE mineral rock that contains Haematite (Iron (III) Oxide).
copper,bauxite,ironore,tin,etc
because usa home consumption is very high thats why it has to import iron ore
In Iron ore processing Mines, when Ironore fines are magnetically separated , and subjected to chemical treatment etc; fine gold is found to occur along with other metals. This is confirmed by both spectroscopic and other methods. This indirectly answers the question that gold in combination with IRON is magnetic ;
Agreed with anonymous. However, do NOT confuse with Iron(III)oxide; archaically, ferric oxide. Iron is if two different oxidation states indicated by the Roman Numerals (II) & (III). Iron(III)oxide is also known as ferric oxide,, and is the mineral, ironore, used in Blast furnaces to make iron metal. There is also Fe3O4 (Iron(VI)oxide, known as magnetite. This is the 'lodestone' used by ancient navigators to find 'north'. As a length of it always hung in the North/South direction.
