copper milling process

ASARCO » Milling

The material that sinks in the first flotation cell goes on to two more flotation cells to recover as much copper as possible. What doesn’t float is called tailings because it goes out the “tail end” of the flotation circuit. About 80 percent of the water used in the milling process is reclaimed and re-used.
