Copper mining. The main stages.

Copper mining There are a number of steps to get nearly pure copper from copper ore. Roll your cursor over the steps in the diagram to see a summary of each one. The ore is enriched using a process called froth flotation. Unwanted material (called gangue) sinks to the bottom and is removed. Roasting: This is where the chemical reactions start.
