Kinetic behaviour of the roasting/selective reduction process with the use of a mixture of bituminous coal and fuel oil as the additive [PDF]

Hemijska Industrija
Lateritic ore is currently the main raw material that allows extraction of Ni by the Caron process. To date, the kinetic behaviour of the roasting/selective reduction process of lateritic nickeli-ferous ores on a pilot scale is largely unknown.

Phase Equilibria in the FeO–Fe2O3–Sb2O3–Sb2O5–SiO2 System in Equilibrium With Metal and in Air/Oxygen Atmosphere

Journal of the American Ceramic Society, Volume 109, Issue 9, September 2026.
ABSTRACT Experimental study and thermodynamic modeling of the phase equilibria in the FeO–FeO1.5–SbO1.5–SbO2.5–SiO2 system in air and 1 atm oxygen, and in equilibrium with Sb/Sb–Ag metal has been undertaken. Experimental data at 575°C–1600°C were obtained using high‐temperature equilibration of mixtures in sealed silica ampoules, Fe3O4 basket/MgO ...
