|
Abstract:
本文从对比的角度主要研究了右水矿区瓷土、瓷石和高岭土的赋矿原岩、赋矿部位、矿石的粒度组成、淘洗率、矿物成分和化学成分等特征差异性。采用薄片鉴定方法研究了赋矿原岩的主要矿物种类、含量、结构构造和岩石主要特征；激光粒度测试研究了矿石(土)的粒度组成与分布；常规淘洗法研究了矿石(土)淘洗率、原矿与精矿的主要有益有害组分含量的变化特征；X射线衍射测试研究了矿石(土)的矿物成分；荧光光谱测试研究了矿石(土)的化学成分；并采用统计法研究总结了赋矿部位等特征；研究成果表明，右水瓷土(瓷石)与高岭土矿的赋矿原岩、赋矿部位和矿石(土)的粒度组成、淘洗率等特征差异性较明显。
This paper mainly studies the differences of the characteristics of the host rock, host position, ore size composition, washing rate, mineral composition and chemical composition of porcelain clay, porcelain stone and kaolin in Youshui mining area. The main mineral species, content, structure and characteristics of the host rock were studied by thin section identification; The particle size composition and distribution of ore were studied by laser particle size measurement; Conventional washing method was used to study ore washing rate and the content characteristics of main beneficial and harmful components in raw ore and concentrate; The mineral composition of ore was studied by X-ray diffraction tests; The chemical composition of ore was studied by fluorescence spectroscopy; The characteristics of ore-hosting sites are studied and summarized by statistical method. The results show that there are obvious differences between the host rock, host position, ore size composition and washing rate between the porcelain clay (porcelain stone) and kaolin.
