多年来,冶金、地质系统物相分析工作者,对铁矿石物相分析方法及其在地质勘探和选矿工艺研究中的应用,做了不少试验研究工作,使铁矿石物相分析方法有了较大的改进.在此基础上,1981年4月地质部和冶金工业部共同颁发的《铁矿地质勘探规范》(试行)中规定,“铁矿基本分析项目主要做全铁(TFe)分析,取消过去分析可溶铁(SFe)的要求.”“采用物相分析确定的磁性铁(MFe)对全铁(TFe)的占有率作为划分矿石类型的依据.”为此,本规范规定“针对不同矿床、不同矿石类型的含铁矿物共生组合特征,选用合理的物相分析方法. Over the years, metallurgical and geological system of phase analysis of the iron ore, phase analysis methods and their application in geological prospecting and beneficiation process research done a lot of experimental research, the iron ore phase analysis method Based on this, in April 1981, the Ministry of Geology and Metallurgical Industry jointly issued the “Geological Prospecting Regulations for Iron Ore (Trial)” stipulates that “the basic iron ore analysis project is to do all-iron (TFe ), Eliminating the requirement for the past analysis of soluble iron (SFe). ”“ The use of magnetic iron (MFe) determined by phase analysis for the share of total iron (TFe) as the basis for the classification of the ore. ”For this reason, this Code Provisions "for different deposits, different ore types of iron ore symbiotic combination characteristics, the selection of a reasonable phase analysis.
