Facts about Metals and Their Ores

Aluminium is one of the most common elements in the Earth’s crust and is found in a variety of silicate ores, which are often a type of clay.
The most common metal ores are oxides and sulphides.
Sulphides are the oldest ores, formed in the Earth’s history when there was a lot of sulphur from volcanic activity.
Oxides formed later when photosynthesis in plants released large amounts of oxygen into the atmosphere.
Iron ore is the most common element in the world and makes up close to 5% of the Earth’s crust. This makes it one of the most abundant rock elements.
