摘要
文章介绍了科甲铝土矿矿石粒级的分布规律及其质量的变化情况,指出矿区铝土矿矿石粒级分布与其所处的岩溶洼地、谷地或缓坡地貌距离原生铝土矿的远近有密切关系,一般受原生铝土矿和岩溶地貌形态发育过程的双重控制.矿石的粒度大小不一,多呈棱角一次棱角状,不同粒级的矿石质量有所差异,矿石粒度越大,矿石品位越好的规律,即矿石品位与粒度为正相关关系.
Abstract
The article introduces the distribution pattern of ore particle size and its quality variations in the Kejia bauxite mine.It points out that the distribution of ore particle size in the mining area is closely related to the distance from the karst depressions,valleys,or gentle slopes to the primary bauxite deposits.Generally,it is controlled by both the primary bauxite deposits and the karst landform development process.The ore particles vary in size and are mostly angular or sub-angular.The quality of ore varies among different particle sizes,with larger ore particles generally having higher grades,indicating a positive correlation between ore grade and particle size.
