- Antimony Mining Process Explained
Antimony is a highly poisonous pollutant that needs to be removed from water to ensured safety. In this work, we have fabricated a novel adsorbent, the ferric-manganese oxide (FeMnO x) nanoparticles embedded cellulose nanocrystal-based polymer hydrogel (FeMnO x @CNC-g-PAA/qP4VP, denoted as FMO@CPqP), specifically …

Antimony metallurgy is the technology that extracts antimony metal from antimony ores or produces antimony compounds. Antimony was discovered in the ancient time, and its name was derived from antimonite. In 1604, a process was invented to extract antimony and antimony sulfide as described by B. Valentine of Germany.
