floatability of molybdenum. This dual action underscores
the agent’s unique ability to target specific mineralogical
properties for optimized separation.
Moreover, the comprehensive investigation into the
interaction dynamics between MSA and galena, using
Pb2+ titration and XPS analyses, confirmed the adsorp-
tion mechanism. The studies conclusively demonstrated
that MSA chemisorbs onto the lead atoms on the galena
surface, validating the hypothesized interaction model and
providing a molecular-level understanding of the depres-
sant’s action.
In conclusion, Mercaptosuccinic Acid emerges not
only as an effective substitute for traditional galena depres-
sants but also as a groundbreaking solution in the realm of
eco-friendly and selective Mo-Pb separation processes.
