Innovations: How Do They Do That? How Copper is Made
The Mine ore is transported to the crushing plant where it is crushed to a size appropriate for the grinding process and then conveyed to the concentrator. After a series of runs through furnaces, where non-copper elements are burned off or separated, the result is a 99 percent pure molten copper, know as "blister".
