difference between metallic and non metallic minerals.

Metallic- An element that reflects light (is shiny). 
Non Metallic- An element that does not reflect light (not shiny).

Metals are malleable substances that are useful and valuable because they are so strong, relatively light, and can be reshaped for many purposes. The availability of metals and the methods to extract and use them have determined technological developments, as well as economic and political power for individuals and nations. 

Nonmetal minerals constitutes a broad class that covers resources from gemstones to sand, gravel, salts, limestone, and soils. Sand and gravel production for road and building construction compromise by far the greatest volume and dollar value of all nonmetal mineral resources and a far greater volume than all metal ores.

Minerals are classified in many ways.
One of the most popular way is based on their luster.
Minerals with metallic luster are classified as metallic minerals and minerals with non-metallic luster are classified as non-metallic minerals.
By and large most metallic minerals as ore are used for extraction of metal(s) but all metallic minerals are not used as ore of metals, e.g. pyrite is a metallic mineral but not used as an ore of iron. Similarly Bauxite (group of minerals) is non-metallic mineral(s) is used for extraction of aluminum and so on.

There is a big difference between Non-metallic minerals and metallic minerals.Metallic minerals are composed primarily of metallic elements and have a metallic lustre and other properties, such as the ability to conduct electricity. Non-metallic minerals do not have these characteristics

Metallic Minerals:

•  Metallic mineral re those minerals which can be melted to obtain new products.
• . Iron, cooper, bauxite, tin, manganese are some examples.
• . These are generally associated with igneous rocks.
• . They are usually hard and have shines or luster of their own.
• . They are ductile and malleable.
•   When hit, they do not get broken.

Non-Metallic Minerals:

•  Non-metallic minerals are those which do not yield new products on melting.
•  Coal, salt, clay, marble are some examples.
•  These are generally associated with sedimentary rocks.
• They are not ductile and malleable.
•  When hit, they may got broken into pieces.

metalli minerals contains metal which non-metallic minerals do not contain metals.
