【摘要】 <正> 本文用穆斯堡尔效应,分析了在400℃、500℃、600℃、700℃、800℃及900℃的温度下,在还原、中性、氧化气氛中,分别焙烧40分钟后,铁矿石样品中各含铁矿物的铁的相对含量,在最佳磁化焙烧温度（650～700℃）下磁性矿相（Fe₃O₄+γ-Fe₂O₃）的相对含量达80～90％,从而为选矿工艺提供了有价值的数据。更多还原

【Abstract】 This paper has systematically analysed the relative contents of the iron in the iron-containing minerals of iron ore samples by Mossbauer spectrometer. The iron ore samples were roasted in reductive atmosphere, neutral atmosphere and oxidation atmosphere at 400℃, 500℃, 600℃, 700℃, 800℃ and 900℃ for forty minutes, respectively. This work has provided valuable data for some iron-steel companies.更多还原
