Ore is a naturally occurring solid material from which a metal or valuable mineral can be extracted. It is typically found in the Earth's crust and can contain various elements, including iron, copper, and gold. The extraction process often involves mining, where the ore is removed from the ground and then processed to separate the valuable components. Different types of ore are classified based on their mineral content and the metals they yield. For example, bauxite is the primary ore for aluminum, while hematite and magnetite are common ores for iron. Understanding ore is essential for industries that rely on metal production and resource management.
