Monothiophosphates are now used widely on copper–gold flotation plants. Mercaptobenzothiazole (MBT, Aeropromoter 404) is a fairly specialized collector (Finkelstein and Poling, 1977) and is the preferred collector for the flotation of gold and gold-carrying pyrite in acid circuits (O'Connor and Dunne, 1991). It is also recommended for ...

Copper extraction - Wikipedia

Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide (usually chalcocite), which can then be activated by the froth flotation plant.
