摘要

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（Fe

+γ-Fe

）的相对含量达80~90%，从而为选矿工艺提供了有价值的数据。

Abstract

This paper has systematically analysed the relative contents of the iron in the ironcontaining minerals of iron ore samples by Mössbauer 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.
