How is Copper Made? | What Is Copper Made of?
The bubbles condense and the water drained off, leaving a mixture called copper concentrate. The mixture contains 25-35% copper, in addition to copper and iron sulfides and small bits of gold, silver and other matter. The leftover waste—known as tailings or gangue—is pumped into settling ponds to dry.
