Hematite and magnetite are best described as:

Explanation:
Hematite and magnetite are iron oxides—minerals made from iron bonded with oxygen. This makes them among the most common iron ores used to extract iron for steel. Hematite has the formula Fe2O3 and magnetite Fe3O4, and neither is carbon-based, silicate, nor a copper mineral. So describing them as combinations of iron and oxygen that are the most common ores best fits what they are and why they’re important.
