Yes, hematite can be formed by inorganic processes.
Magnetite belongs to the spinel group of minerals
Bauxite and hematite are called ores, since they both produce useful minerals.(Bauxite - Aluminum)(Hematite - Iron)
Yes, Hematite is a non silicate mineral. It is part of the Oxides group.
Not Radioactive
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

Yes, hematite is a mineral.
Hematite is an ore of iron.
Hematite intermixed with Goethite is also known as Rainbow Hematite and is wonderfully iridescent.
Hematite, also spelled as hæmatite, is the mineral form of Iron(III) oxide (Fe2O3), one of several iron oxides. Hematite crystallizes in the rhombohedral system, and it has the same crystal structure as ilmenite and as corundum. Hematite and ilmenite form a complete solid solution at temperatures above 950°C. Hematite is a mineral, colored black to steel or silver-gray, brown to reddish brown, or red. It is mined as the main ore of iron. Varieties include kidney ore, martite (pseudomorphs after magnetite), iron rose and specularite (specular hematite). While the forms of hematite vary, they all have a rust-red streak. Hematite is harder than pure iron, but much more brittle. Maghemite is a hematite- and magnetite-related oxide mineral.
Hematite is a mineral composed largely of iron. Hematite rosary beads would be beads made of hematite used for a rosary.
Hematite is a mineral of iron: Fe2O3.
Hematite has a dramatic red streak.
Hemitite has the properties of naturally occuring, inorganic, and crystal structure. Brick is man-made, and the chemical composition varies.
Hematite is an oxide of iron.
hematite is a mineral that is used for jewelry
