Ores are rocks that contain important elements in concentrations high enough for profitable extraction.
Explanation:
The most valuable ores contain valuable metals like copper, gold, iron, and aluminium.
For example, aluminium is the most abundant element in the Earth's crust.
Bauxite ore (below) contains from 50 - 70% of aluminium oxide.
The bauxite is mined and refined to extract aluminium.
