沉积型钛铁矿品位计算方法

Calculation method for grade of sedimentary ilmenite

沉积型钛铁矿品位计算中时常出现简化计算公式,忽视钛铁矿中TiO2实际含量和钛物相分布中钛铁矿占比等因素,导致钛铁矿品位计算数据偏差,影响钛铁矿储量计算和项目经济测算。为了减少钛铁矿品位计算的错误,本文以莫桑比克和马拉维钛铁矿项目勘查资料数据为基础,论述钛铁矿物中TiO2实测含量及钛物相分析中钛铁矿占比的意义,正确运用钛铁矿品位计算公式,使沉积型钛铁矿品位计算更接近实际,为提升钛铁矿砂矿资源储量和项目经济性测算的准确性提供重要支撑。

Simplified calculation formula often appears in the grade calculation of sedimentary ilmenite,ignoring factors such as TiO2 content in ilmenite minerals and the proportion of ilmenite in titanium phase, whichleads to deviation in the calculation data of ilmenite grade and affects the calculation of ilmenite reserves and theeconomic calculation of the project. In order to reduce the error in the calculation of ilmenite grade, based on theexploration data of the ilmenite projects in Mozambique and Malawi, this paper discusses the actual content of TiO2in the ilmenite mineral and the significance of the proportion of ilmenite in the titanium phase analysis, andcorrectly uses the calculation formula of ilmenite grade to make the calculation of the grade of sedimentary ilmenitecloser to the actual content, It provides important support for improving the accuracy of ilmenite placer resourcereserves and project economic estimation.
