galena, pyrite, and hematite all happen to be distinct in their metallic luster.
Slate is mainly composed of quartz and muscovite or illite, often along with biotite, chlorite, hematite, and pyrite and, less frequently, apatite, graphite, kaolin, magnetite, tourmaline, or zircon as well as feldspar.

some of our samples of pyrite are paramagnetic
Gold is an element.
They are all minerals which contain iron.
Hematite can appear gray in color, but will exhibit a reddish to rust-colored streak.
It can be scratched by a diamond, corundum, topaz, and quartz.
The primary mineral would be... hematite. Many other minerals could be present, to one degree or another, including magnetite, pyrite, quartz, etc.

There are a wide variety of metallic resources. These include chalcopyrite, gold, hematite, molybdenite, native copper, as well as pyrite.
Pyrite (fools gold) reacts with Oxygen to make Hematite (Fe2O3) and Sulpher dioxide (SO2) The reaction is oxidation of pyrite. 2FeS2 + 3.5O2 - - Fe2O3 + 2SO2
The term "iron ore" is quite general, and can be applied to a number of different minerals, like hematite, magnetite, goethite, or pyrite.
