| 摘 要： | 以一批进口土耳其铬矿石为例,对所取的40个样品进行0～ 10 mm、10 ～ 50 mm、50 ～ 150 mm、150～ 250 mm及大于250 mm五个区间的粒度筛分,分析粒度不均匀的铬矿石在各粒度区间内组分含量和所占质量百分比的差异情况.根据分析结果对40个样品在50 ～ 150 mm区间内的质量百分比与样品总组分含量进行相关性分析,结果表明:两者的相关系数为0.466,相关系数的显著性概率为0.002,小于0.01,说明在50～150 mm粒度区间内矿石的质量百分比与样品的总含量的相关性是高度显著的,提出为了提高粒度不均匀的铬矿石取样代表性,应首先保证在所含矿石质量百分比与总组分含量相关性最大的粒度区间内(50 ～ 150 mm),所取矿石样品与实际货物中矿石的质量百分比相一致.

| Abstract: | Forty samples of imported Turkish chrome ore were classified into five size groups (0-10 mm, 10-50 mm, 50-150 mm, 150-250 mm and greater than 250 mm) in which the difference of constituent contents and weight proportions were studied. The relevance of weight proportions in the 50-150 mm particles and constituent contents of the 40 samples was studied. The results show a correlation coefficient of 0.466 and a significance probability of 0.002, which indicates a highly significant correlation between them. Therefore, in order to improve the representativeness of sampling, the weight proportions in the 50-150 mm particle group should be correlated between the sampling ore samples and the actual cargo. |
