It is oxygen that is chemically combined with the iron to form iron(III) oxide. That iron oxide, which is Fe2O3, is what is in hematite, and that's what we want to recover and process. A link can be found below.
Iron. It is iron (III) oxide Fe2O3 (with the '2' and '3' small and subscript)
Hematite is a mineral. This is from wikipedia: A mineral is a naturally occurring solid with a definite chemical composition and a specific crystalline structure. A rock is an aggregate of one or more minerals. Have a look at this page in wiki about hematite: http://en.wikipedia.org/wiki/Haematite
not soluble in water but in ethanol or other alcohols.
Either a single atom of the element, if there is no subscript number in the formula, or the number of atoms of the element commonly joined to each other in a polyatomic but mono-elemental molecule of the element if the formula does include a subscript number.
Carbon can form four bonds with different elements and/or other carbon elements.
yes it can
There are a variety of iron ores such as the minerals limonite, hematite, magnetite, that are rich in the element iron and mined extensively for the production of iron and steel.. These minerals, in addition to iron, contain other elements.

A relatively new process, magnetation, will aid in the separation of hematite from other rock. Used in the waste tailing of iron ore mining, the magnets attract the hematite for use.
yes.
not soluble in water but in ethanol or other alcohols.
There are very many elements which will do that.
Yes it is and in other places around the world.
Australia is the largest producer of hematite, with significant deposits found in the Pilbara region of Western Australia. Other major producers include Brazil and China.
The primary mineral would be... hematite. Many other minerals could be present, to one degree or another, including magnetite, pyrite, quartz, etc.

yes it the main ore in iron.there are other ores too.
