Raw XPS survey data associated with article Gangue-driven surface processes during oxidative acid column leaching of chalcopyrite

This folder contains raw data from XPS surveys associated with the article "Gangue-driven surface processes during oxidative acid column leaching of chalcopyrite" (to be submitted to the Hydrometallurgy journal). This dataset contains a time series of XPS surveys corresponding to the analysis of chalcopyrite samples subjected to oxidative acid leaching in the absence (series B) or presence (series C) of chloride ions. These samples were placed at different locations within the two column systems, each composed of three columns connected in series. B0/C0 samples were located at the start of each system, while B1/C1, B2/C2, and B3/C3 samples were located after the first, second, and third column, respectively, for each system. The subfolders within each of the B0-B3 or C0-C3 folders correspond to each specific sample followed over time (the experiment lasted 72 days) in each location.

Further details on the methodology followed to obtain these results can be found in Larrabure, G., Batchelor, A., Salinas-Farran, L., Neethling, S. J., & Brito-Parada, P. R. (2025).

本文件夹收录了与投稿至《湿法冶金》（Hydrometallurgy）期刊的论文《黄铜矿氧化酸柱浸过程中脉石驱动的表面演化过程》相关的X射线光电子能谱（X-ray Photoelectron Spectroscopy, XPS）原始测试数据。本数据集包含一系列XPS测试时序数据，对应两组黄铜矿样品的分析结果：两组样品分别在无氯离子（序列B）与有氯离子（序列C）的环境中进行氧化酸柱浸处理。所有样品被安置于两套串联柱浸系统的不同取样位置，每套系统均由3根串联的浸柱构成。其中B0/C0样品位于每套系统的起始端，B1/C1、B2/C2及B3/C3样品则分别对应每套系统中第1、第2、第3根浸柱后的取样位置。序列B0至B3与C0至C3的各子文件夹，分别对应各取样位置随实验进程采集的单个样品（本次实验总时长为72天）。关于获取本测试结果所采用的实验方法的详细细节，可参阅Larrabure G、Batchelor A、Salinas-Farran L、Neethling S J、Brito-Parada P R于2025年发表的论文《评估柱浸过程中的表面过程：结合X射线光电子能谱与扫描电镜-能谱仪（Scanning Electron Microscope-Energy Dispersive X-ray Spectroscopy, SEM-EDS）的时空多尺度分析方法》（《矿物工程》（Minerals Engineering）, 228卷, 2025年3期, https://doi.org/10.1016/j.mineng.2025.109359）。但该方法学论文并未涵盖本研究数据集收录的原始数据分析内容。
