What are Minerals

What are minerals? Where can we find minerals or how do they look? Minerals are present in food and on earth as well. The form of minerals is different in food and earth substances. Are you perplexed about minerals and curious to know more about them? Then, you have come to the right place. In this blog, we shall discuss some of the basics of minerals, their uses, and their type.

Minerals are inorganic solids that exist naturally and have a specific chemical composition and atomic structure. All of their physical properties are derived from this foundation. A rock, for example, is a body of undifferentiated mineral stuff or a combination of one or more minerals. Granite, basalt, limestone, and sandstone are all common rocks.

Physical Properties of Minerals

Minerals are easy to identify based on their physical properties. Minerals have unique physical characteristics. Here are the minerals physical properties:

  • Hardness means resistance to scratch
  • Tenacity means resistance to impact
  • Specific gravity means relative density
  • Cleavage is the tendency of some crystals to split along planes of the weakest atomic bonding
  • Magnetism
  • Electrical Conductivity
  • Acid Reactivity

Examples of Minerals

We have covered minerals and their physical properties will help you identify them better. Here are examples that will help you understand the concept in-depth. We are surrounded by minerals in many forms. Check out the examples of minerals:

  • Minerals include gold, diamonds, rock salt, and graphite used to form pencil lead
  • Sodium chloride is the mineral that makes up table salt because it occurs in crystals shaped like little cubes, it has an organized structure
  • Quartz, also known as silicon dioxide, is another common mineral. The hexagonal shape of its crystals is unique. Coal is a carbon-based material that was first captured by living beings through the process of photosynthesis
  • Limestone is a type of rock made up of only one mineral: calcium carbonate. Igneous, sedimentary, and metamorphic rocks can be separated into three types based on their origin on Earth

Classification Of Minerals

Minerals are divided into two categories: primary minerals and secondary minerals. Minerals created by the volcanic process, which involves the cooling of liquid materials called magma, have been classified as primary, whereas those formed by other processes have been classified as secondary. Primary minerals such as olivine, anorthite, and hornblende, had entirely decomposed, and the byproducts recombined to create secondary minerals.

Different Types of Minerals

The chemistry and crystal form of minerals are used to classify them. Metallic minerals and Non-metallic minerals are the two sorts of minerals:

Metallic Minerals

Metallic minerals have a lustrous appearance and a chemical composition that includes metals. These minerals have the potential to be used as a metal source and can be mined. Metallic minerals include the following: Metallic minerals include manganese, iron ore, and bauxite, which are classified as ferrous or non-ferrous. Non-ferrous minerals are those that do not contain iron, while ferrous minerals do.

Non-metallic Minerals

Minerals that have a non-metallic sheen or shine to them are known as non-metallic minerals. Their chemical composition does not contain any extractable metals. Non-metallic minerals include limestone, gypsum, and mica. For example, Bauxite ore is found largely in worn rocks. In some areas, bauxite deposits can be found in volcanic rocks.

Minerals in Food

Do you know our food items are rich in various vitamins and minerals? Here are some of the minerals found in food items:


When it comes to your bones, calcium is the most important macro mineral. This mineral contributes to the development of strong bones, allowing you to perform tasks such as standing up straight and scoring the game-winning goal. It also helps in the development of strong, healthy teeth, which are necessary for chewing delectable foods.

  • Milk, cheese, and yogurt are examples of dairy products
  • Leafy green vegetables, such as broccoli, tinned salmon, and sardines with bones


Iron is required by the body to transfer oxygen from the lungs to the rest of the body. To stay healthy and alive, your entire body requires oxygen. Iron helps in the synthesis of hemoglobin the component of red blood cells that transports oxygen throughout the body.

  • Meat
  • Beans
  • Tuna and salmon
  • Dried fruits like raisins
  • Eggs
  • Baked potato with skins

Potassium is necessary for the normal functioning of your muscles and nervous system.

  • Citrus fruits like oranges
  • Low-fat milk and yogurt
  • Bananas
  • Tomatoes
  • Potatoes and sweet potatoes with skins


Zinc is beneficial to your immune system, which is your body’s defence system against illnesses and infections. It also promotes cell growth and helps in the healing of wounds such as cuts.

  • Legumes, such as beans, split peas, and lentils
  • Nuts, such as cashews, almonds, and peanuts
  • Beef, pork, and dark meat chicken

Practice Questions

Here are some practice questions to test yourself and see how familiarized your are with the concept of minerals:

Q1. What are minerals?

Ans. Minerals are substances that occur naturally on the planet. They’re putting together rock blocks. Minerals are inorganic solids with a crystal structure that are generated naturally by geological processes. Mineralogy is the study of minerals.

Q2. What are the benefits of minerals?

Ans. Minerals, like vitamins, aid in the growth, development, and maintenance of your body. Minerals are used by the body for a variety of purposes, including the formation of strong bones and the nervous system development. Some minerals are also required for the production of hormones and the maintenance of a regular heartbeat.

Q3. What are four mineral science sources?

Ans. The elements oxygen, silicon, copper, iron, calcium, sodium, potassium, and magnesium make up about 99 percent of the minerals in the Earth’s crust. Quartz, feldspar, bauxite, cobalt, talc, and pyrite are all common minerals. 

Q4. Which mineral is the most common in the human body?

Ans. Calcium is an essential mineral in the human body, accounting for 1.5 to 2% of the total body weight. An adult human’s body has approximately 1,200 g of calcium, with bones accounting for nearly all of it.

Q5. Is salt considered a mineral?

Ans. Salt, often known as rock salt or halite in its natural form as a crystalline mineral, is a mineral consisting primarily of sodium chloride (NaCl), a chemical compound belonging to the wider class of salts. Seawater has a large amount of salt, which is the principal mineral element.
