鄂西仁和坪向斜煤系高岭岩的矿石特征及应用前景

Ore features and application prospects of kaolinitic rock in coal measures of the Renheping syncline, western Hubei

对鄂西仁和坪向斜二叠系梁山组煤系高岭岩成矿地质特征及矿石组分的研究表明,该地区高岭岩矿床属碎屑沉积型,以硬质高岭岩为主,矿层层位稳定,矿石中高岭石多呈隐晶至微晶片状结构,且纯度高(高岭石含量90%～95%),具有低Mn(<30×10-6)高Ti(>0.5%)的特点,矿石中Fe、Mg、Ca、Na、K、Mn、S、As及重金属元素Cu、Pb、Zn、Cd、Tl等有害组分含量普遍较低。综合分析认为本区高岭岩属功能化极强的优质高岭石原料,在橡胶、塑料、涂料、药用包装等领域有广阔的应用前景。

Study of geological features and ore composition of kaolinitic rock in coal measures of the Permian Liangshan Formation in the Renheping syncline, western Hubei, indicates that the kaolinitic rock deposit is of clastic sedimentary type and dominated by hard kaolinitic rock, with a persistent ore horizon. Kaolinite in the ore is mostly aphanitic to microcrystalline flaky textures, has a high purity (the kaolinite content is 90% to 95%) and is characterized by low Mn (<30 ×10-6) and high Ti (>5%). The harmful components Fe, Mg, Ca, Na, K, Mn, S and As and heavy metals elements Cu, Pb, Zn, Cd and Tl are all lower. Integrated analysis suggests that the kaolinitic rock may serve as high-quality functional kaolinite raw material and has good prospects in the rubber, plastic, coating and medicinal package industries.
