Abstract:
Objective: To evaluate the quality of Limonitum from different mineral genesis and select its high quality mineral resources by analyzing its mineral compositions and content. Method: The mineral compositions and content of different samples were analyzed by polarizing microscope and X-ray diffraction,and goethite content was taken as the evaluation index. SPSS 16.0 statistical software was used for hierarchical cluster analysis of the mineral compositions in different samples. Result: Limonite,quartz,illite and mica kaolinite were the main components of Limonitum from leaching disseminated type. Sedimentary type limonite was mainly composed of limonite,quartz and albite. Residual-alteration type limonite was mainly composed of limonite,quartz,diopside and carnallite. The content of goethite in limonite was highest (46.4%) in sedimentary type limonite from Jiangxi province,followed by that in leaching-disseminated type from Jiangsu province (17.9%) and leaching-disseminated type from Shandong province (0.5%). The content of sedimentary goethite was higher than 12.0%and the content of leaching-disseminated type goethite was between 0.5%and 18.0%, with significant difference; and the content of residual-alteration type was below 3.0%. Cluster analysis of mineral components in different samples showed that 6 samples of leaching-dissemination type were clustered into one group,3 samples of sedimentation type were clustered into one group,and 2 samples of residual-alteration type were clustered into one group. Conclusion: The quality of sedimentary type Limonitum in Jiangxi is the best. Generally,the quality of sedimentary type is better than that of leaching-disseminated type, and the quality of leaching disseminated type is better than that of residual-alteration type.
