Applications
⛏️ Mineral Flotation Collector
Benzyl Hydroxamic Acid is extensively used as a collector for oxide minerals, particularly:
-
Rare Earth Ores (Monazite, Bastnaesite)
-
Ilmenite (Titanium Ore)
-
Cassiterite (Tin Ore)
-
Wolframite (Tungsten Ore)
It provides excellent selectivity and flotation performance, especially under neutral to slightly alkaline pH, making it ideal for differential flotation circuits.
🧪 Chelating and Analytical Agent
In addition to its flotation application, BHA is utilized in coordination chemistry as a chelating agent and in analytical laboratories for metal ion detection and separation.
