Ores of Copper (Cu) - Copper, a versatile and highly conductive metal, has been a cornerstone of human civilization for centuries.From electrical wiring to coins, copper's importance cannot be overstated. Copper is extracted from various naturally occurring ores that differ in their chemical composition, physical properties, and economic significance.

The process varies slightly depending on the type of ore that is being mined. Sulfide ores are first put through a jaw or gyratory crusher to reduce the rocks to about 7 - 8 inches. This material is then fed to a secondary grinder that further reduces the size to about 1 - 2 inches. ... About 80% of copper from ore is generated using flotation ...
