What is an ore, exactly?
An ore is a natural rock or sediment containing valuable minerals, usually metals, concentrated enough to be economically mined and processed for profit, providing sources for everything from iron and copper to gold, though it also includes nonmetallic minerals. The key is the concentration: the material must have enough of the desired element (like iron, aluminum, or gold) to justify the cost of extraction, a measure known as its "grade". Ores are not pure metals but compounds (like oxides or sulfides) mixed with other rock, requiring processes like smelting to separate and refine the valuable substance.What is ore in simple words?
