What are the different types of minerals explain them briefly?
What are the two main types of minerals? There are two types of minerals: macro minerals and trace minerals. Macro means “big” in Greek (and your body needs more macro minerals than trace minerals). The macro mineral group consists of calcium, arsenic, magnesium, sodium, potassium, chloride and sulphur.
A mineral is a natural substance with distinctive chemical and physical properties, composition, and atomic structure. The definition of an economic mineral is broader, and includes minerals, metals, rocks and hydrocarbons (solid and liquid) that are extracted from the earth by mining, quarrying and pumping.
| Mineral | Function |
|---|---|
| Phosphorus | Important for healthy bones and teeth; found in every cell; part of the system that maintains acid-base balance |
| Magnesium | Found in bones; needed for making protein, muscle contraction, nerve transmission, immune system health |
| Sulfur | Found in protein molecules |
On the basis of composition minerals are classified mainly as metallic and non-metallic minerals. Metallic minerals contain metal in raw form. Metals are hard substances that conduct heat and electricity and have a characteristic luster or shine. Iron ore, bauxite, manganese ore are some of the examples.
Differences in chemical composition and crystal structure distinguish the various species. Within a mineral species there may be variation in physical properties or minor amounts of impurities that are recognized by mineralogists or wider society as a mineral variety.
There are two kinds of minerals: macrominerals and trace minerals. You need larger amounts of macrominerals. They include calcium, phosphorus, magnesium, sodium, potassium, chloride and sulfur. You only need small amounts of trace minerals.
Minerals can be found throughout the world in the earth's crust but usually in such small amounts that they not worth extracting. Only with the help of certain geological processes are minerals concentrated into economically viable deposits. Mineral deposits can only be extracted where they are found.
Scientists can distinguish more than 4,000 different minerals but many are very rare. About 200 minerals make up the bulk of most rocks. The feldspar mineral family is the most abundant. Quartz, calcite, and clay minerals are also common.
In nature there are many minerals: around 2000 species are known. Some of them are very rare, while some others are very popular. But only around thirty of them compose the Earth's crust rocks. These minerals are made up of several chemical elements that distinguish them.
Minerals that contain iron are called ferrous minerals. Example of ferrous minerals is Chromites, Iron ore, and manganese. Minerals that do not contain iron are called non-ferrous minerals. Examples of nonferrous minerals are lead, silver, gold, and copper.
How are minerals classified briefly describe each type for Class 8?
Minerals are classified into two types: Metallic and non-metallic. Metallic Minerals: They are further sub-divided into ferrous and non-ferrous. Ferrous minerals: They contain iron. Examples are iron ore, manganese ore, chromite, pyrite, nickel, and cobalt.
Types of minerals: On the basis of composition, minerals are classified into metallic and non-metallic types. Metallic minerals contain metals in raw form. Metallic minerals are of two types: (a) Ferrous and (b) Non-ferrous. Non-metallic minerals do not contain metals.
Minerals are found in different types of rocks. Metallic minerals are usually found in igneous and metamorphic rocks that form large plateaus. Examples: iron ore is found in north Sweden, copper, and nickel in Canada. In igneous and metamorphic rocks in South Africa, iron, nickel, chromites, and platinum are found.
A mineral can be made of an element or a compound. Its chemical composition is different from other minerals. Each type of mineral has physical properties that differ from others. These properties include crystal structure, hardness, density, and color.
Minerals form when rocks are heated enough that atoms of different elements can move around and join into different molecules. Minerals are deposited from salty water solutions on Earth's surface and underground.
Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.
We need minerals to make cars, computers, appliances, concrete roads, houses, tractors, fertilizer, electrical transmission lines, and jewelry. Without mineral resources, industry would collapse and living standards would plummet.
Introduction. Minerals are grouped by their chemical composition. Silicates, oxides, sulfates, sulfides, carbonates, native elements, and halides are all major mineral groups.
Minerals are those elements on the earth and in foods that our bodies need to develop and function normally. Those essential for health include calcium, phosphorus, potassium, sodium, chloride, magnesium, iron, zinc, iodine, chromium, copper, fluoride, molybdenum, manganese, and selenium.
Uses of Minerals:
Some minerals which are usually hard are used as gems for making jewellery. Copper is used in almost everything from coins to pipes. Silicon is used in almost everything from coins to pipes. Silicon is used in the computer industry which is obtained from quartz.
What is mining explain its different types Class 8?
Mining: The process of taking out minerals buried under the rocks is called mining. There are two main methods of mining, viz. open-cast mining and shaft mining. Open Cast Mining: When minerals are taken out by removing the surface layer, the process is called open-cast mining.
Minerals are compounds naturally produced on Earth. They have a clear structure and chemical composition. There are more than 3000 known minerals.
Minerals include calcium, phosphorus, sodium, potassium, magnesium, manganese, sulfur, chloride, iron, iodine, fluoride, zinc, copper, selenium, chromium and cobalt (which is part of the vitamin B12/cobalamine).

Mineral is a naturally occurring inorganic solid with a definite chemical composition and a crystalline structure.
Answer: Minerals are naturally occurring substances which have certain physical properties and definite chemical composition. Minerals are very useful for mankind. Some minerals like coal, natural gas and petroleum are used as fuels.
