Elements: Many pure elements are found in the form of minerals in ores or mines. For example, uncombined carbon is often found in its pure state in the form of graphite or more rarely as diamond. Gold, silver and sulfur are other elements which are also found in its pure state. Even though these are pure elements they qualify to be known as minerals, but no chemical process is required on them further.
Oxides: When an ore is found in which one or more elements are combined with oxygen, it is an oxide mineral. These may have chemical formulas of type XO (MgO, ZnO, CuO, etc.), X2O (Cu2O), X2O3 (Al2O3, Fe2O3), XO2 (MnO2, SnO2) and XY2O4 (MgAl2O4, FeCr2O4). The oxide minerals, are mostly of metallic elements. Example: hematite, magnetite, cuprite. Silicates and oxides are the most common types of minerals in volcanoes, especially after an eruption.
Carbonates: The carbonate type of minerals are formed when a single carbonate ion (CO32-) reacts with a metal ion of complementing polarity. Example: siderite (FeCO3), smithsonite (ZnCO3), calcite (CaCO3). Carbonate minerals are used in making cement and other bonding material.
Sulphates: The mineral class which includes the sulfate ion (SO42-) within its molecular structure, is categorized as sulphate mineral. Minerals like Gypsum (CaSO4·2H2O) and Barite (BaSO4) are examples of sulphate minerals.
Organic Minerals: This class of minerals include biogenic substances, genesis or origin of which can be attributed to a geological processes. Organic minerals include all types of oxalates, mellitates, citrates, cyanates, acetates, formates, hydrocarbons, etc. Example of organic mineral includes whewellite, moolooite, mellite, fichtelite, carpathite, evenkite and abelsonite.

How many different groups of crystal structure are there in minerals?
There are about four different groups of crystals structures that are available in the minerals. The four have different orientations of the close-packed layers.

What are the 2 main groups of minerals in food?
The minerals found in food can be categorized into two groups; macrominerals, and trace minerals. Macrominerals are usually found in large quantities in food, and are required in larger quantities for the body. Trace minerals are found in small amounts in food, and are needed in smaller amounts in the diet. Macrominerals: Sodium, potassium, chloride, calcium, phosphorus, magnesium, sulfur. Trace minerals: Iron, zinc, iodide, selenium, copper, fluoride, chromium, molybdenum, manganese.
Why isn't cement a mineral?
No. A rock is an assemblage of at least two different minerals. One mineral can't be two or more minerals.
How many different groups of crystal structure are there in minerals?
There are about four different groups of crystals structures that are available in the minerals. The four have different orientations of the close-packed layers.
What are the different mineral?
There are over four thousand different minerals. There are some major groups of minerals, which include groups such as oxides, silicates, carbonates, phosphates, borates, halides, sulfides, and native elements.

What does a mineral mean?
Minerals are the building blocks of rocks. They are non-living, solid, and, like all matter, are made of atoms of elements. There are many different types of minerals and each type is made of particular groups of atoms. Different types of minerals have different crystal shapes.
How are minerals divided?
Minerals are divided into groups based on their chemical composition and crystalline structure. The two main groups are silicate minerals, which are made of silicon and oxygen, and non-silicate minerals, which are composed of other elements. Within these groups, minerals are further classified based on their specific properties and characteristics.
What are the features of two major groups of minerals?
silicate minerals and non silicate minerals
What are features of two major groups of minerals?
nonsilicate and silicate minerals
All minerals in the sulfate and sulfide groups contain what element?
All minerals in the sulfate and sulfide groups contain sulfur.
How many main types of minerals are there?
There are roughly 3,000 different types of minerals, which can be categorized into around eight main mineral groups. Some of these groups include silicates, carbonates, sulfides, and oxides. Each group has its own distinct chemical composition and physical properties.
Are the two features of the two major groups of minerals?
nonsilicate and silicate minerals
Classifications of foods?
Food is anything that is taken into body for nourishment and living.
What are the two major groups of minerals?
The two major groups of minerals are silicate minerals and non-silicate minerals. Silicate minerals contain silicon and oxygen, while non-silicate minerals do not contain these elements. Silicate minerals make up the vast majority of Earth's crust.
