minerals in the tabular form
Answers
Answer:
Metallic minerals are classified into two categories:
1) Ferrous minerals: The metallic minerals that contain iron are known as ferrous minerals. In the total production of metallic minerals, 75% is constituted by ferrous metallic minerals. Its common examples include iron ore, manganese, chromite and nickel.
2) Non-Ferrous minerals: The metallic minerals that don't contain iron are known as non-ferrous minerals. They don't have magnetic properties and are generally more resistant to corrosion than ferrous minerals.
Non-Metallic Minerals:
As the name suggests, non-metallic minerals are the minerals that do not contain metals, e.g. limestone, mica, coal, gypsum, dolomite, phosphate, salt, manganese, granite etc. They are used in various industries to produce a variety of products, e.g. mica is used in electrical industry, limestone is used in cement industry. Furthermore, they are also used in the production of fertilizers and manufacturing of refractories. They are generally found in sedimentary rocks that are formed by the aggregation of various materials like minerals, remains of organisms, rock particles etc.
Based on the above information, some of the key differences between metallic and non-metallic minerals are as follows:
Metallic minerals Non-metallic minerals
They are the minerals that contain one or more metallic elements. They are the minerals that do not contain metallic elements.
They are generally hard and have a shiny surface. They don't have a shiny surface and are not as hard as metallic minerals.
They are mostly found in igneous and metamorphic rocks. They are mostly found in sedimentary rocks.
They are ductile and malleable, can be beaten into sheets and stretched to produce wires. They are not ductile and malleable, so they break into pieces when hit hard.
They are a good conductor of heat and electricity. They are a poor conductor of heat and electricity.
They can be melted to produce new products. They do produce new products on melting.
They are less abundant than non-metallic minerals. They are more abundant than metallic minerals.
Examples: Copper, tin, iron, manganese, gold etc. Examples: Carbon, gypsum, potash, precious stones, boron, sulphur, mica, quartz, dolomite, diamond etc.
