how is iron made is the question.hey its me.again.need MORE help with science homeworkugh!!so as i said beforeif u have any answers plzs tell me fast.thanks a bunch xoxoxoxoxoxo
Iron IS made. It's just made by nuclear fusion that requires very high pressure and temperature (this is the case in/on the Sun and in the Earth's core). Man would rather purify iron that was made by the Sun and Earth and bound to other elements to become a mineral because purification (probably) requires less energy than bringing about fusion. The trick question answer is cute and right in a way. Nefertiri E answered the question in a nice, practical way.
Iron isn't made, it's mined and then refined. Iron ore is dug out of the ground. It's mixed up with other things (mostly different combinations of iron and oxygen). To get rid of the other chemicals, the iron ore is heated to an extremely high temperature. Carbon (coal) is added. The carbon binds to the oxygen and eventually creates carbon dioxide gas (the same gas people expel when they breathe out). This gas is expelled, leaving behind the iron. When some of the oxygen and carbon are left, then the product is called pig iron. Pig iron contains about 4 % carbon. Pure or nearly pure iron is called wrought iron -- it's very strong, but it's heavy, hard to melt or mold, can grow brittle, and it rusts like crazy. This is a bad thing if you're using it to make, say, the hull of a ship. Today, most iron is blended with a small amount of other metals to make steel. It's easier to mold into useful items, is a little lighter, and and is more resistant to rust.
