If this copper is crushed to produce a clean stream for flotation process, we end up with the powder that looks like this. After flotation, we produce a stream of tailings that looks like this and a stream of recovered ore that looks like this. Flotation is a powerful tool to recover small amounts of valuable minerals from low grade ores.
