贺州市八步区塘贡钾长石矿地质特征及开发利用

Geological Characteristics and Development and Utilization of TanggongPotassium Feldspar Deposit in Babu District, Hezhou City

作为一种重要的非金属矿产资源,钾长石被广泛应用于陶瓷、玻璃和水泥等建材行业。本文结合贺州市八步区塘贡钾长石矿的区域地质背景,分析矿床地质特征及其成因,然后设计钾长石矿开发利用方案,为钾长石矿的开发利用提供理论指导。经详查,矿床类型为风化花岗岩型钾长石矿。钾长石深埋于侏罗纪晚期的花岗岩岩体中,强风化层及中风化层是钾长石矿的主要蕴藏区域。评估结果显示,矿区钾长石资源量丰富,矿床储量规模为中型。经设计,矿山开采规模为大型,钾长石原矿开采量为120万t/a,主要产品有2种,即钾长石精矿和建筑用砂,可以实现资源的高效利用。

As an important non-metallic mineral resource,potassium feldspar is widely used in building materials industries such as ceramics,glass,and cement.Based on the regional geological background of Tanggong potassium feldspar deposit in Babu district,Hezhou city,this paper analyzes the geological characteristics and genesis of the deposit,and then designs a development and utilization plan for potassium feldspar deposit,providing theoretical guidance for its development and utilization.After detailed investigation,the deposit type is weathered granite type potassium feldspar ore.Potassium feldspar is deeply buried in the granite rock mass of the late Jurassic period,and the strongly weathered and moderately weathered layers are the main areas of potassium feldspar deposits.The evaluation results show that the potassium feldspar resources in the mining area are abundant,and the reserve scale of the deposit is medium-sized.According to the design,the mining scale of the mine is large,and the mining output of potash feldspar raw ore is 1.2 million t/a,there are two main products,namely potash feldspar concentrate and construction sand,which can realize the efficient utilization of resources.
