INDIAN GEOGRAPHY

Detailed explanation-1: -Metallic Minerals are minerals in which metal elements are present in their raw form. Non-metallic minerals do not contain any metal substances in them. When metallic minerals are melted a new product is formed. In the case of non-metallic minerals, you don’t get any new product after such a process.

Detailed explanation-2: -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.

Detailed explanation-3: -Metallic minerals are of two types: Ferrous minerals and Non-ferrous minerals. Ferrous minerals are minerals that contain iron. A non-ferrous mineral does not contain iron but may contain some other metal.

Detailed explanation-4: -The mineral hematite can have both metallic or nonmetallic luster; hematite with metallic luster is used to make jewelry.

Detailed explanation-5: -Nonmetallic minerals are, for example, sand, gravel, limestone, clay, and marble. Such materials lack metallic characteristics like good electric and thermic conductivity, luster, rigor, and malleability; they are, however, essential for many industries.
