Subject: Science , asked on 12/9/12

"All ores are minerals but all minerals are not ores". Justify the statement with examples

EXPERT ANSWER

Pankaj Singh , Meritnation Expert added an answer, on 13/9/12

Minerals are naturally occurring inorganic solids with a crystalline structure and a definite range of chemical formula. Ores are concentrations of minerals in rock that are high enough to be economically extracted for use. All ores are minerals, but all minerals are not necessarily ores.


 

For example: Aluminium is extracted from the ore bauxite.

It is so because metals cannot be extracted from minerals in a convenient way. E.g.:- Aluminum metal is found in both minerals: clay and bauxite. Aluminum metal is extracted only from bauxite in a convenient way. So, bauxite is an ore of aluminum. On the other hand, it is not extracted from clay so clay remains only as mineral not ore of aluminum.

 An ore is a type of rock that contains  minerals  with important  elements  including metals. The ores are extracted through mining; these are then refined to extract the valuable element(s). All minerals are not ores because not all minerals are valuable enough to be mined.
