摘要

本文研究了利用金属和矿物基矿石开采的副产品尾矿作为一种新的水泥替代材料。本文以13个矿山尾矿样品的化学物理特性为研究对象。在本研究中，化学计量学被应用于同时考虑所有参数，并在大数据集中获得潜在关系的彻底筛选。层次聚类分析(HCA)根据(dis)相似的特征对样本进行分组，主成分分析(PCA)将主导变量和与样本的关系可视化。HCA的应用突出了尾矿之间按特征进行清晰分组的特点。同时，通过主成分分析，确定了尾矿样品的主要化学和物理特征。因此，化学计量学提供了对尾矿物理和化学特性的全面概述。关键词:尾矿，化学计量学，水泥置换

Applying Chemometrics to Evaluate Mine Tailings’ Potential As Partial Cement Replacement

This study investigates the utilization of mine tailings, the by-product originating from metal- and mineral-based ore mining, as a new cement replacement material. This paper is based on the chemical and physical characteristics of 13 mine tailing samples. In this study, Chemometrics were applied to consider all parameters simultaneously and obtain a thorough screening of potential relations in the large data set. Hierarchical Cluster Analysis (HCA) groups samples according to (dis)similar features and Principal Component Analysis (PCA) visualizes predominating variables and relations to samples. The application of HCA highlighted a clear grouping between mine tailings according to characteristics. Meanwhile, PCA identified the predominant chemical and physical characteristics in the mine tailing samples. Chemometrics therefore provided a thorough overview of mine tailings’ physical and chemical characteristics. Keywords: mine tailings, chemometrics, cement replacement
