  • Chemistry Notes for class 12 Chapter 6 General Principles

    Minerals and Ores The naturally occurring substances in the form of which the metals occur in the earth crust are called minerals. Every mineral is not suitable for the extraction of the metal. The mineral from which the metal is economically and conveniently extracted is called an ore. Thus all ores are minerals but all minerals are not ores.
