Study Notes
Mineral Basics
- A mineral is a naturally occurring inorganic solid substance with a specific chemical composition and structure.
Distribution of Minerals
- Metallic minerals are generally found in igneous and metamorphic rocks.
- Non-metallic minerals are commonly found in sedimentary rocks.
Properties of Minerals
- Iron exists in the form of hematite (Fe2O3) or magnetite (Fe3O4).
- Iron ore is primarily composed of iron oxides, with hematite being the main component.
Mineral Resources
- Minerals are considered non-renewable resources because they take thousands of years to form and once extracted, they cannot be replaced in a short period of time.
