In the chapter on the removed parts of the metal and non-metals begin the appearance of the metal and end with rust and their prevention is:

Appearance of instruments:

  • The metals found in the crust are in the form of Elements or a compound called minerals.
  • Some metals form as salt dissolved in seawater.
  • Minerals that contain iron are called iron minerals (eg Haematite) and minerals that are beneficially mined are called ores.
  • The earth's crust is made up of more than 2000 minerals, but of these, only six are very saturated and have a high hand.
  • These six minerals are rich in feldspar, quartz, pyroxenes, amphiboles, mica and olivine.
