Basically its alumina followed by various other oxides,,,however you find in theory that Al2O3 is one of the prime component of slag obtained used for many other purposes in other industries........hope dis helpd;-)

What is a waste product from iron ore?
slag
How Is Iron Ore Purified using Carbon?
Iron ore, carbon (also called 'coke') and limestone are heated in a blast furnace. The carbon reacts with oxygen blasted into the furnace from the bottom to form carbon monoxide. Carbon monoxide then reduces the the iron ore to molten iron and becomes carbon dioxide in the process. The limestone in the furnace melts the impurities and decomposes to calcium oxide (quicklime). Quicklime and impurities mix together to form 'slag'. The slag floats on top of the molten iron so that the iron can be drained off at the bottom.
How is oxygen removed from iron ore?
Iron ore is mixed with coke (almost pure carbon from coal) and roasted at high temperatures. The carbon reacts with the oxygen to produce carbon dioxide leaving the elemental iron.
Is iron and iron ore the same?
no they are not the same because iron is a metal that is obtained from its ore called iron ore
What is the ore of iron called as?
Iron ore.
Is wasted product from iron ore?
slag
What is a waste product from iron ore?

How do you remove iron from iron ore?
Iron ore comes as a mixture of Ferric and Ferrous Oxide (forms of iron oxide). At the smelter it is mixed with coke and limestone. The coke is the reducing compound. The limestone or some other substance is the flux. Coke is made from heating coal to a high temperature. The coke becomes almost pure carbon. The mixture is placed into a large brick lined open top furnace. It is set on fire. The oxygen from iron is transferred to the coke. It turns into Carbon dioxide. The iron oxide turns into iron. The limestone mixed with the impurities in the iron ore becomes slag. From time to time a door in the side is opened up to let out liquid iron and slag. The liquid iron is sent to the next process where it may be turned into steel. The slag becomes like glass.
Are iron and iron ore the same thing?
No; iron ore is mixed with copper and smelted; the ore needs to be refined to extract pure iron. You cannot make a tool out of ore, but rather with pure iron.
What is a slag heep?
A slag heap is a hill/mountain of waste matter from underground mining such as coal and iron ore. Slag heaps are a part of an industrial landscape less evident in modern times
How is iron removed from the earth's crust?
Iron ore is removed with dynamite and lots of heavy equipment. It starts as iron ore and is mixed with coke (carbon). This is a displacement reaction which means that the iron is separated from the ore and you have iron on its own.
What happens to the element in iron ore when the ore is mixed with carbon and heated?
Iron ores most often contain iron combined with oxygen. The carbon comes from a material called coke, which is made from coal. When heated, the carbon reacts with oxygen in the ore, leaving the purified iron metal behind.

What happend to the elements in iron ore when the ore is mixed with carbon and heated?
It becomes stronger then before
What is the method for purifying iron?
After iron ore is mined it is crushed into a powder then injected into a blast furnace. Under the extreme temperatures the ore melts and since iron is more dense than the impurities, it sinks to the bottom. This leaves a film of "slag" (impurities) on top. The slag is then skimmed off so only the metal remains.
How is iron refined?
Iron is refined by a blast furnace. A furnace is filled with iron ore, coke (which is charcoal made from coal) and limestone. Huge amounts of air are blasted into the furnace, the calcium from the limestone combines with silicates (which are minerals containing silicon and oxygen) to form slag (which is run off ore from the furnace). A layer of liquid iron collects under the slag, at the bottom of the furnace. The liquid iron is periodically let out to cool. Charlie
