Implication

This investigation demonstrates enhanced zinc leaching kinetics in blast furnace dust using crotonic acid, indicating potential for resource recycling.

Key Points

Ultrasonic leaching of zinc achieved 92.79% efficiency compared to regular methods, demonstrating improved extraction.
Under optimal conditions, including 240 W ultrasonic power and a 1 mol/L crotonic acid concentration, leaching of iron reached 15.45%.
Kinetic analysis revealed that both ultrasonic-assisted and regular leaching processes are controlled by different mechanisms.
Ultrasonic action showed a significant role in fragmenting BFD particles, allowing more efficient interaction with crotonic acid.
