Iron ore is a heterogeneous mixture.
Iron ore is a mixture.
Iron ore is a compound.
Pure iron has just iron in it. As an ore it is a mixture of other minerals and soil as well.
A solid may be an element (iron), a compound (iron oxide), a mixture (iron ore).
It is a mixture of an Iron compound and a rock substrate. Iron ores are usually rich in Iron Oxides (a compound) and minerals. Since the iron is not chemiically bonded to the mineral substrate it is a mixture.
concentration
Iron ore is not normally smelted, instead it is reduced in a blast furnace with a mixture of coke & limestone. The coke burns removing the oxygen from the iron ore and melting the resulting iron. The limestone neutralizes acidic sulfur compounds and acts as a flux.
Stainless steel mixture, element, ore or mineral is an ally of iron and carbon. The carbon is the primary alloying element.
An iron alloy (Explanation): Iron metal is a pure substance, so it cannot be a solution, so it's not that one. An iron ore is found in nature and is iron chemically combined with other substances, so it's not a mixture because mixtures aren't chemically combined. Iron rust is also chemically combined iron with oxygen, so it's not a mixure. Therefore, the iron alloy is the correct answer (btw, an alloy is where you heat the metal to a liquid and mix in other metals like zinc to make pennies and stuff)
iron ore
Iron is a compound iron nail is a iron ore which means that the iron nail is a mixture of metals such as copper and zinc added to make the nail stronger.
