长期以来,地质和物相分析工作者就发现,铁矿石的基本分析项目,对指导生产实践存在许多问题.为了弄清和解决这些问题,我们做了一点工作,现汇报如下,以供讨论.一现行铁矿石基本分析项目及存在的问题按现行地质规范的规定,铁矿石基本分析试样要求分析全铁、可溶铁、氧化亚铁三个项目.在进行地质总结和矿床评价时,应用这些化验结果是基于以下认识的:即可溶铁就是工业可用铁;全铁减去可溶铁就是硅酸铁(指一种铁矿石含于含铁硅酸盐中的铁量,简称硅酸铁),它在工业上不能利用;化验氧化亚铁的目的在于圈定氧化带,计算
For a long time, geological and phase analysis workers found that the basic analysis project of iron ore has many problems in guiding the practice of production, and we have done a little bit of work to clarify and solve these problems and are reported below for discussion A basic analysis of existing iron ore projects and existing problems According to the provisions of the current geological norms, iron ore basic analysis of the sample required analysis of total iron, soluble iron, ferrous oxide three projects in the geological summary and deposit evaluation , The application of these assay results is based on the recognition that soluble iron is an industrially available iron; total iron minus soluble iron is iron silicate (meaning an iron content of iron ore contained in ferrous silicates , Referred to as iron silicate), it can not be used in industry; the purpose of testing ferrous oxide is to delineate the oxidation zone, calculated
