Major Mineral Classifications: Metallic, Non-Metallic & More
Types of Minerals is essential in chemistry and helps students understand various practical and theoretical applications related to minerals, geology, and nutrition. This topic is key for understanding earth science, resource management, and the chemical needs of living organisms.
What is Types of Minerals in Chemistry?
A mineral is a naturally occurring inorganic solid with a definite chemical composition and crystalline structure. The classification of minerals appears in chapters related to geochemistry, inorganic compounds, and environmental science, making it a foundational part of your chemistry syllabus. Knowing the types of minerals helps us identify resources and understand their uses in daily life.
Molecular Formula and Composition
Every mineral has a unique molecular composition. For example, sodium chloride (NaCl) is a mineral in the halide group, and calcium carbonate (CaCO3) belongs to the carbonate group. Minerals contain elements from the Periodic Table arranged in repeating structures. This helps students connect mineral chemistry to actual chemical formulas and bonding patterns.
Main Types of Minerals: Metallic & Non-Metallic
Minerals are mainly divided into metallic minerals and non-metallic minerals. This helps in resource identification and usage decisions. Understanding their differences is an important chemistry learning goal.
| Metallic Minerals | Non-Metallic Minerals |
|---|---|
| Contain metal elements (Fe, Al, Cu) | Do not contain metal elements |
| Shiny, lustrous, good conductors | Dull appearance, non-conductors |
| Examples: Hematite, Bauxite, Gold | Examples: Quartz, Diamond, Mica |
| Used for extracting metals | Used in industry, nutrition, jewelry, etc. |
7 Major Mineral Classifications
Minerals are further classified based on their chemical composition into seven main groups. This arrangement is helpful for both chemistry and earth science studies.
- Native elements (e.g., Gold, Copper)
- Silicates (e.g., Feldspar, Quartz)
- Oxides (e.g., Hematite, Magnetite)
- Sulfides (e.g., Pyrite, Galena)
- Carbonates (e.g., Calcite, Dolomite)
- Halides (e.g., Rock Salt, Fluorite)
- Phosphates (e.g., Apatite, Monazite)
Types of Minerals in Food/Nutrition
In biology, minerals are divided into major minerals (macrominerals) and trace minerals (microminerals). These are vital inorganic nutrients needed for body functions and are found in different foods.
| Major Minerals | Trace Minerals |
|---|---|
| Needed in large amounts | Needed in small (trace) amounts |
| Examples: Calcium, Sodium, Potassium, Magnesium, Phosphorus, Chloride, Sulfur | Examples: Iron, Zinc, Copper, Iodine, Selenium, Manganese, Fluoride, Chromium |
| Sources: Dairy, vegetables, fruits | Sources: Meat, seafood, nuts, whole grains |
Types of Minerals in Geography & Rocks
In geography, minerals are classified by how they form and their chemical makeup. For students, this means understanding which minerals are found in rocks, soil, and the Earth's crust.
- Igneous minerals (form from magma/lava)
- Sedimentary minerals (form from sediment processes)
- Metamorphic minerals (change by heat/pressure)
For example, granite is an igneous rock rich in silicate minerals, while limestone is a sedimentary rock made mainly from calcite (a carbonate mineral).
Types of Minerals Chart & Pictures
A classification chart helps students see the types of minerals at a glance. Visual aids and lists make it easier to remember which class a mineral belongs to.
| Mineral Type | Example Name | Chemical Formula | Key Use |
|---|---|---|---|
| Silicate | Quartz | SiO2 | Glass, electronics |
| Oxide | Hematite | Fe2O3 | Iron extraction |
| Carbonate | Calcite | CaCO3 | Cement, building |

Frequent Related Errors
- Mixing up rocks with minerals—they are not the same.
- Thinking metallic minerals must look metallic—some are not shiny!
- Forgetting that minerals in food/nutrition are different from geological minerals.
Uses of Types of Minerals in Real Life
Different types of minerals are used for construction, nutrition, industry, and technology. For example, hematite delivers iron for making steel, while quartz is essential in making glass and watches. Nutritional minerals like calcium and iron are used by our bodies to build bones and carry oxygen. Vedantu regularly covers these applications in its interactive classes for better concept clarity.
Relation with Other Chemistry Concepts
Types of minerals connect to concepts such as elements and compounds, properties of metals and nonmetals, and inorganic chemistry in general. This makes learning about minerals crucial for understanding matter, bonding, and environmental science basics.
Step-by-Step Reaction Example
- Extraction of iron from hematite:
1. Take hematite ore (Fe2O3) and coke (C) as raw materials.
2. Heat in a blast furnace with limestone.
3. The reaction: Fe2O3 + 3C → 2Fe + 3CO
4. Iron is separated for industrial use.
Lab or Experimental Tips
Remember mineral types by their appearance and simple tests. Metallic minerals are usually heavy and conductive. Vedantu educators suggest using streak tests and hardness tests for easy identification in school labs.
