This research investigates how varying thermal history affects the reduction behaviors of copper slag pellets.
Examined phase evolution of reduced products through analysis methods including morphology, x-ray diffraction, scanning electron microscopy, and energy dispersive spectroscopy.
Conducted experiments at temperatures of 1050°C, 1100°C, and 1150°C.
Analyzed the metal ratio and grain growth in reduced products under different thermal treatments.
A maximum metal ratio exceeding 90% achieved at 1100°C for over 90 minutes.
Liquid phase formation negatively impacted metal ratio at 1150°C.
Effective suppression of liquid phase can be achieved by reducing pellets at 1100°C before heating to 1150°C.
