some of our samples of pyrite are paramagnetic
Chalcopyrite, hematite, magnetite, and pyrite are all types of minerals that can be found in the Earth's crust. They are commonly used in various industrial applications, such as in the production of metals and as gemstones. Additionally, these minerals are all sulfide or oxide compounds containing different combinations of iron, copper, and sulfur.

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.

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.
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.

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.
Copper: Mined primarily as chalcopyrite, an important source of copper. Gold: Extracted from gold ores such as quartz and pyrite. Iron: Mainly obtained from hematite and magnetite ores. Zinc: Usually found in sphalerite, a zinc sulfide mineral. Aluminum: Mainly sourced from bauxite ore, a mixture of hydrated aluminum oxides.
