XPS data - Polymetallic (Mn-Fe-Pb) sulfides subject to cyanide leaching under sonication conditions and after an alkaline pretreatment

X-ray photoelectron spectroscopy (XPS) was employed to follow surface changes during leaching of a silver-containing polymetallic (Mn-Fe-Pb) sulfide under a) conventional leaching, b) ultrasound-assisted leaching, and c) leaching of a sample after an alkaline pretreatment. Leaching experiments were conducted in triplicate and for each experiment a mineral sample was taken at determined times during the leaching process.本研究采用X射线光电子能谱（X-ray photoelectron spectroscopy, XPS）追踪含银多金属（锰-铁-铅）硫化物浸出过程中的表面变化，实验分别在三种工况下开展：a）常规浸出、b）超声辅助浸出，以及c）经碱性预处理后的样品浸出。所有浸出实验均设置三组平行重复，且每次实验均在浸出过程的预设时刻采集矿物样品。
