淄川—博山地区伊利石化高岭石粘土岩地质特征及其应用

Geological Characteristics and Application of Illitization of Kaolinite Clay in Zichuan-Boshan Area

摘要:

论述了淄川—博山一带的伊利石化高岭石粘土岩的区域地质概况及成矿地质条件，按自然分布结合地质情况，划分为3个成矿带，叙述了各成矿带分布及含矿层特征。以南坡矿区为例，详细论述了矿层赋存特征，矿体的规模、厚度及其质量，研究了矿石类型、化学成分及主要物理性能指标，类比研究了加工技术性能，经简单水选即可达到较为理想的选矿指标，具有高效、低成本优势；结合有关研究，认为该类粘土岩是在较高温度条件下由高岭石粘土岩加钾水化转变而成。山东省该类矿床总体勘查程度低，具有较好的找矿潜力，但优质粘土资源找矿难度大。

Abstract:

Regional geological condition and mineralization of illitization of kaolinite clay rocks in ZichuanBoshan area have been introduced in this paper. According to natural distribution, and combining with geological conditions, this area can be divided into three metallogenic belts. Characteristics of metallogenic belt distribution and orebearing layers have been studied. Setting southern slope of the mining area as an example, occurrence characteristics, size, thickness and quality of ore bodies have been introduced in detail, types, chemical composition and physical performance indicators of ore have been studied, and processing technology has been determined as election by simple water. It can achieve good beneficiation indicators with high efficiency and low cost. It is regarded that clay rocks in this area is change by the potassium increase hydration of kaolinite clay rock at a high temperature condition. Exploration level of this kind of deposit in Shandong province is low. It has a good prospecting potentiality, but it is very difficult to explore clay resources with high quality.
