Metal ores are naturally occurring rocks or minerals from which metals can be extracted. These ores contain a high concentration of specific metals, making them valuable for mining and industrial processes. Common examples of metal ores include iron ore, copper ore, and aluminum ore. The extraction of metals from these ores typically involves mining, crushing, and refining processes. Once the metal is separated from the ore, it can be used in various applications, such as construction, manufacturing, and electronics. The availability of metal ores is crucial for the global economy and technological advancement.
