Depressants for Mining | Syensqo
Syensqo's depressants are employed in diverse applications. For instance, they are used in copper-molybdenum separations, where they assist in the depression of copper and iron sulfides. Another use is in the flotation of simple metal sulfides and complex polymetallic-bearing ores, where they depress iron sulfides such as pyrite and marcasite.
