一、讨论前言冶金矿山(包括地质勘探)矿石类型划分是生产的一个重要环节。矿石类型划分错误,会直接影响矿山生产,并造成资源的浪费。传统磁性率(即TFe/FeO)划分磁铁矿床矿石类型,是解放初期由苏联专家米德耶夫、萨拉耶夫等人引进到我国冶金地质勘探和矿山生产中来的。尔后,我国广大地质工作者和矿山工作者通过长期的实践,虽然在应用上曾经不断地改进,但其基本原则却没有变动,一直沿用到今天。长期以来,我们通过生产实践和研究工作深深感到:应用传统磁性率对于矿石由磁铁矿组成并遭受不同程度氧化而伴生有赤铁
First, the discussion Preface Metallurgical mines (including geological exploration) Ore classification is an important part of production. Ore classification error, will directly affect the mine production, and cause waste of resources. The traditional magnetic fraction (ie, TFe / FeO) divides the ore type of magnetite ore deposits, which was introduced into the metallurgy geological prospecting and mine production of our country by the Soviet experts Medyev and Salayev in the early period of liberation. Later, through the long-term practice of the vast number of geological workers and mine workers in our country, their basic principles have not changed even though they have been continuously improved in application and have been used today. For a long time, we deeply felt through the practice of production and research that the application of the traditional magnetic susceptibility is accompanied by hematite when the ore is composed of magnetite and is subjected to different degrees of oxidation
