Which of the following is a metallic mineral resource?

Explanation:
Metallic mineral resources are minerals that contain metal in a form that can be mined to produce metal. Hematite is an iron oxide ore, Fe2O3, and is a major source of iron used in steelmaking, so it fits this definition as a metallic mineral resource. Gypsum, halite, and sand are non-metallic minerals: gypsum is used for plaster and cement, halite for rock salt, and sand mainly as a construction material or in glassmaking, but none provide metals directly. So hematite best satisfies the idea of a metallic mineral resource.
