Mineral vs. Ore: What's the Difference?
In essence, not all minerals are ores, but all ores contain minerals. Ores are classified based on their metal content and the feasibility of extracting that metal. This means that the economic value of the metal and the cost of extraction are key determinants in defining an ore. 8. For instance, aluminum is extracted from the mineral bauxite.
