(2009) found that most of the copper-bearing species in slag flotation tailings were occluded in the slag phase and thus unable to interact with the collector. Therefore, the slag flotation tailings are inferior in terms of leaching when compared to the slag because most of the liberated copper phases have been removed by flotation.

Standard copper sulphide flotation collector reagents are sulphur-based thiol class collectors, which can be grouped into the main xanthate, dithiophosphate, thionocarbamate and thiocarbamate families.

Copper-Molybdenum ores

Recovery of copper is by standard flotation reagents identified in the copper ore flotation description. Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability.
