They are all minerals which contain iron.

Pyrite is typically a brassy yellow color and has a metallic luster, while chalcopyrite is a copper-yellow color and tarnishes to an iridescent blue or purple color. Additionally, pyrite has a hardness of 6-6.5 on the Mohs scale, whereas chalcopyrite has a hardness of 3.5-4.
The three minerals that are metals and can scratch glass are iron pyrite (pyrite), hematite, and magnetite. These minerals have a high hardness level, allowing them to scratch glass and show metallic luster.

The difference between the iron in magnetite and hematite is the charge. Hematite has all 3+ iron ( the iron when make the mineral loses 3 electrons) and magnetite has some 2+ iron (it only loses 2 electrons).
There are a wide variety of metallic resources. These include chalcopyrite, gold, hematite, molybdenite, native copper, as well as pyrite.
The primary mineral would be... hematite. Many other minerals could be present, to one degree or another, including magnetite, pyrite, quartz, etc.
Pyrite and magnetite are both metallic minerals that are heavy and have a metallic luster. They are often found in association with each other in certain types of rocks, such as igneous rocks and metamorphic rocks. Both minerals are known for their magnetic properties, with magnetite being strongly magnetic and pyrite being weakly magnetic.

They are extracted from the earth as ores. Some commercially valuable ore minerals are magnetite and hematite for iron production, Sphalerite for zinc production, and chalcopyrite (not to be confused with pyrite, it's pretty much useless) for copper. There are many other ore minerals out there, I've only listed a few.
Pyrite is typically a brassy yellow color and has a metallic luster, while chalcopyrite is a copper-yellow color and tarnishes to an iridescent blue or purple color. Additionally, pyrite has a hardness of 6-6.5 on the Mohs scale, whereas chalcopyrite has a hardness of 3.5-4.
galena, pyrite, and hematite all happen to be distinct in their metallic luster.
Pyrite, chalcopyrite, galena, and hematite are common rocks that exhibit metallic lusters. These minerals contain metals such as iron, copper, lead, and sulfur, giving them a shiny, metallic appearance.
