What are minerals?

Minerals are naturally occurring, inorganic substances that have a specific chemical composition and a specific crystal structure. They are found in the Earth's crust and are often extracted for use as raw materials in a variety of industries.

There are over 4,000 known minerals, and they can be classified into several different categories based on their chemical composition and other properties. Some common mineral groups include silicates, oxides, sulfides, carbonates, and halides.

Minerals are an important part of our lives, as they are used in a wide range of industries and applications. Some common uses of minerals include construction, electronics, jewelry, medicine, agriculture, energy production, transportation, manufacturing, personal care, and many others.

Minerals are also an important source of nutrients for both humans and animals. Many minerals, such as calcium, iron, and zinc, are essential for maintaining good health and are found in a variety of foods and supplements.

Minerals typically have chemical names that are based on their chemical composition and crystal structure. These names are usually derived from the International Mineralogical Association (IMA) approved list of mineral names. In addition to their chemical names, minerals may also have CAS (Chemical Abstracts Service) numbers, which are unique identifiers that are assigned to specific chemical substances by the American Chemical Society. CAS numbers are used to help identify and track chemicals and are often used in scientific and regulatory contexts.

For example, the mineral quartz has the chemical name silicon dioxide and the CAS number 14808-60-7. The mineral calcite has the chemical name calcium carbonate and the CAS number 471-34-1. The mineral pyrite has the chemical name iron sulfide and the CAS number 12096-62-7.

It's important to note that not all minerals have been assigned CAS numbers, as these numbers are typically only assigned to substances that are used in commercial applications or that are of significant scientific interest. However, most minerals do have chemical names that are based on their chemical composition and crystal structure.

Mining

There are several different methods of mining that are used to extract minerals from the Earth. Some of the most common methods include:

Open-pit mining:

Open-pit mining is a surface mining method in which an open pit is created to extract minerals that are located near the surface. This method is often used to extract minerals such as coal, copper, and iron ore.

Strip mining:

Strip mining is a surface mining method in which layers of soil and rock are removed to expose minerals that are located below the surface. This method is often used to extract minerals such as coal, phosphate, and limestone.

Underground mining:

Underground mining is a method of mining in which tunnels are dug underground to access minerals that are located below the surface. This method is used to extract minerals such as gold, silver, and diamonds.

Placer mining:

Placer mining is a method of mining in which alluvial deposits of minerals (such as gold, diamonds, and tin) are extracted from rivers, streams, and other bodies of water.

In-situ leaching:

In-situ leaching is a method of mining in which minerals are extracted from the ground by injecting a solution into the ore deposit and allowing the minerals to be dissolved and extracted. This method is often used to extract minerals such as uranium.

The specific method that is used will depend on the location and type of minerals being mined, as well as the equipment and resources available.

Chemicals used in mineral mining and their applications

There are many chemicals that are used in mineral mining and processing. The specific chemicals that are used will depend on the type of minerals being mined and the processing methods that are being used. Some common chemicals that are used in mineral mining and processing include:

Cyanide:

Classifications and grouping.

Minerals are typically classified according to their chemical composition and crystal structure. The chemical composition of a mineral refers to the specific elements that make up the mineral, such as silicon, oxygen, and aluminum in the case of quartz. The crystal structure of a mineral refers to the arrangement of atoms within the mineral's crystal lattice.

One way that minerals are classified is by their dominant chemical element. For example, minerals that are primarily composed of oxygen and silicon, such as quartz, are classified as silicates. Minerals that are primarily composed of a single element, such as gold or copper, are classified as native elements. Other common classes of minerals include carbonates, sulfates, and phosphates.

Finally, minerals can be classified based on their occurrence, such as whether they form in igneous, metamorphic, or sedimentary rocks, or whether they are found in a specific type of environment, such as in hydrothermal veins or in sedimentary deposits.

Here are a few examples:

Silicates:

· Quartz

· Feldspar

· Mica

· Epidote

· Hornblende

Native elements:

· Gold

· Copper

· Silver

· Diamond

· Graphite

Carbonates:

· Calcite

· Dolomite

· Magnesite

· Siderite

· Smithsonite

Sulfates:

· Gypsum

· Barite

· Anglesite

· Celestite

· Turquoise

Phosphates:

· Apatite

· Monazite

· Wavellite

· Turquoise

· Vivianite

Minerals can be grouped in a variety of ways, depending on the specific characteristics or properties that are being considered.

By chemical composition:

Minerals can be grouped based on the specific elements that they are composed of. For example, minerals that contain silicon and oxygen (such as quartz, feldspar, and mica) are known as silicates. Minerals that contain carbon (such as diamonds and graphite) are known as carbonates.

By crystal structure:

Minerals can be grouped based on the specific arrangement of atoms in their crystal structure. For example, minerals that have a cubic crystal structure (such as pyrite and galena) are known as cubic minerals. Minerals that have a hexagonal crystal structure (such as quartz and beryl) are known as hexagonal minerals.

By hardness:

Minerals can be grouped based on their relative hardness, which is a measure of their resistance to being scratched. The Mohs scale of mineral hardness is a commonly used system that ranks minerals on a scale from 1 (softest) to 10 (hardest). For example, talc is a soft mineral with a hardness of 1, while diamond is a hard mineral with a hardness of 10.

By color:

Minerals can also be grouped based on their color. For example, minerals that are red or pink (such as garnet and rhodochrosite) are known as red minerals. Minerals that are yellow or gold (such as pyrite and citrine) are known as yellow minerals.

By luster:

Minerals can be grouped based on their luster, which is a measure of the way that they reflect light. For example, minerals that are metallic (such as pyrite and galena) have a metallic luster, while minerals that are non-metallic (such as quartz and feldspar) have a non-metallic luster.

By cleavage:

Minerals can be grouped based on the way that they break or split when subjected to stress. For example, minerals that have a good cleavage (such as mica and talc) break easily along smooth, flat planes. Minerals that have a poor cleavage (such as quartz and feldspar) break in an irregular or splintery manner.

By density:

Minerals can be grouped based on their density, which is a measure of their mass per unit of volume. For example, minerals that are denser (such as gold and platinum) are typically heavier than minerals that are less dense (such as talc and gypsum).

By transparency:

Minerals can also be grouped based on their transparency, which is a measure of how much light can pass through them. For example, minerals that are transparent (such as diamond and topaz) allow light to pass through them, while minerals that are opaque (such as quartz and feldspar) do not allow light to pass through them.

By use:

Minerals can also be grouped based on their common uses. For example, minerals that are used as abrasives (such as garnet and corundum) are known as abrasive minerals. Minerals that are used as gemstones (such as diamonds and emeralds) are known as gem minerals.
