Mineral vs. Ore: What's the Difference?
To further elucidate, consider pyrite, often known as "fool's gold." While pyrite is a mineral, it isn't an ore for gold because it doesn't contain gold in a form or quantity that can be economically extracted. The distinction between mineral and ore, therefore, is largely economic, with ores offering a financial incentive for extraction.
