Vitamins and Minerals. Vitamins and minerals are micronutrients required by the body to carry out a range of normal functions. However, these micronutrients are not produced in our bodies and must be derived from the food we eat. Vitamins are organic substances that are generally classified as either fat soluble or water soluble.
No headers. Chemical formulas form the basis for the standard mineral classification system used today. It is generally called the Dana System of Mineralogy and was created in the mid-19th century by American mineralogist, James Dwight Dana (the same mineralogist who produced the definition of a mineral discussed above in Section …
Minerals are divided into two types namely metallic and non-metallic. 1. Metallic Minerals. Metallic minerals exhibit lustre in their appearance and consist of metals in their chemical composition. These minerals serve as a potential source of metal and can be extracted through mining. Examples of metallic minerals are Manganese, iron ore and ...

Classification of Minerals. Minerals are classified as either major minerals or trace minerals, depending on the amount needed in the body. Major minerals are those that are required in the diet in amounts larger than 100 milligrams each day. These include sodium, potassium, chloride, calcium, phosphorus, magnesium, and sulfur.
What is the important classification of minerals? Minerals with the same anionic or anionic group in their arrangement have a clear family resemblance. For example, all carbonates are identical to each other.
Apart from the free gases in Earth's atmosphere, some 20 elements occur in nature in a pure (i.e., uncombined) or nearly pure form. … See more

Classification. Classification, as defined by Heiskanen, is a method of separating mixtures of minerals into two or more products on the basis of the velocity with which the particles fall through a fluid medium. The carrying fluid can be a liquid or a gas. In mineral processing, this fluid is usually water, and wet classification is generally ...
