The concentration of these minerals in an ore body is low. Typical copper ores contain from % Cu to 1 or 2% Cu. Pure copper metal is mostly produced from these ores by concentration, smelting, and refining. About 80% of the world's copperfromore is produced by concentration/smelting/ refining of sulfide ores.
