A study on selective flotation in low and high pyritic ...

Copper-pyrite separation usually occurs at the rougher flotation stage via enhancing the pulp pH to greater than 9, which is performed in the conducted flotation tests. Therefore, pyrite tends to be strongly depressed due to the hydrophilic surface produced by the presence of hydroxyl ions in the pulp.
