Hematite vs Magnetite
Hematite's straightforward iron and oxygen recipe gives it one kind of behavior, while magnetite's mix of ferrous and ferric iron creates different magnetic properties. Though both are iron oxides, this subtle difference in chemistry leads to distinct appearances, behaviors, and uses for each mineral.
