前几年,金吉谢普矿床的研究工作揭示了矿床北部MgO、P_2O_5和不溶残渣化合物之间的相互关系。这使对MgO的化学分析部分(20％)能用直接法完成,而其余试样的MgO含量用计算公式确定 MgO=20.4-0.205(2.7P_2O_5++不溶残渣)式中2.7P_2O_5—岩石中的磷酸盐量(φ)。随着勘探和采矿工作转到矿床南部,揭示出的矿石中的相关关系尚未改变,但其中各组分的数量比,随磷酸盐堆积相状况和随后的白云化和铁化过程的变化而变化。在应用以前确定的系数时,矿物中组分比的变化
A few years ago, the work of the Jinjishipu deposit revealed the correlation between MgO, P_2O_5 and insoluble residue compounds in the northern part of the deposit. This allows the chemical analysis of MgO part (20%) can be done using the direct method, and the rest of the sample MgO content is calculated using the formula to determine MgO = 20.4-0.205 (2.7P_2O_5 ++ insoluble residue) where 2.7P_2O_5 rock phosphate Quantity (φ). As exploration and mining operations move to the southern part of the ore deposit, the correlations revealed in the ore have not changed, but the quantitative ratios of the components vary with the state of the phosphate accumulation phase and subsequent changes in the cloud and ironification processes .
