Metallic ores are naturally occurring minerals that contain valuable metals. These ores are mined from the earth and processed to extract metals like iron, copper, aluminum, and gold. The extraction process often involves crushing the ore and using chemical methods to separate the metal from other elements. The quality of metallic ores is measured by their metal content, known as ore grade. Higher-grade ores contain a larger percentage of metal, making them more economically viable to mine. The mining and processing of metallic ores play a crucial role in supplying raw materials for various industries, including construction, electronics, and manufacturing.
