Some Important Ores for Extraction of Metals and Non-Metals
Ores are naturally occurring materials that contain a high enough concentration of a metal or non-metal to make it economically viable to extract them. Some important ores for the extraction of metals include bauxite for aluminum, hematite for iron, chalcopyrite for copper, galena for lead, and sphalerite for zinc. The extraction of these metals from their ores involves various processes such as crushing, grinding, and smelting.
