in static air at 850-1 000 ℃ The oxidation kinetics was studied by means of discontinuous thermo- gravimetric analysis (TGA). The tested conditions were 850, 900, 950 and 1 000 ℃ for 1, 3, 5, 10, 25, 50..., TiO2 and TiO, which are dense, stable and continuous. The results of X-ray diffraction coincide with those of oxidation kinetics. From an analysis of energy-dispersion spectrometry (EDXS......
: In order to provide theoretical foundation for the combination of separation-metallurgy of Ni-Mo ores. X-ray diffraction (XRD) analysis was measured for Ni-Mo crude ores roasted in 800 ℃ atmosphere for 1.5 h, differential thermal (DTA) and thermo gravimetric (TG) analysis of the Ni-Mo ores in air and argon were conducted. Simultaneously, flotation test were conducted for Ni-Mo crude ores......
