Write an essay on metallic minerals.

• Metallic minerals can be defined as those minerals with a metallic lustre and having properties of metals like high specific gravity, malleability, ductility, conductivity, etc.

• Gold is a very common example. It has industrial use, and it is heavily used in jewellery making. It is used in medical fields as well. Gold is generally detected by chemical methods.

• Silver is another example which has vast use in making jewellery, currency, utensils, water purifiers, etc. It has high electrical conductivity and appreciable thermal conductivity.

• Lead is heavy metal, but it is soft and malleable. It has a low melting point. It is used for construction and plumbing purposes. It is used for making paints and alloys.

• Copper is another example of a metallic mineral. It is soft, malleable and ductile. It has high values of thermal and electrical conductivity. It is used for making ornaments, construction purpose, alloy making, etc.
