Journal ArticleDOI
The role of cupric ions in the oxidative dissolution process of marmatite: A dependence on Cu2+ concentration.
Xiaoyu Meng,Hongbo Zhao,Hongbo Zhao,Hongbo Zhao,Menglin Sun,Yisheng Zhang,Yanjun Zhang,Xin Lv,Hyunjung Kim,Mikhail Vainshtein,Shuai Wang,Guanzhou Qiu,Guanzhou Qiu +12 more
TL;DR: Electrochemical measurement and X-ray photoelectron spectroscopy analysis indicated that Cu2+ was first adsorbed on the marmatite surface and then produced Cu-S surface species, thus catalyzing the oxidative dissolution process.
Journal ArticleDOI
Mineralogical phase transformation of Fe containing sphalerite at acidic environments in the presence of Cu2.
Yisheng Zhang,Yisheng Zhang,Hongbo Zhao,Hongbo Zhao,Xiaoyu Meng,Xiaoyu Meng,Pengfei Ou,Xin Lv,Xin Lv,Luyuan Zhang,Luyuan Zhang,Liu Lixin,Fashang Chen,Guanzhou Qiu,Guanzhou Qiu +14 more
TL;DR: The action mechanism of cupric ions on sphalerite dissolution in acidic environments is furtherly clarified and a strong correlation between the cupric ion consumption with the pH value variation is discussed and the effects of the formed new phase on the dissolution kinetics of marmatite were researched.
Journal ArticleDOI
Scandium extraction from silicates by hydrometallurgical process at normal pressure and temperature
Yanjun Zhang,Yanjun Zhang,Hongbo Zhao,Hongbo Zhao,Menglin Sun,Menglin Sun,Yisheng Zhang,Yisheng Zhang,Xiaoyu Meng,Xiaoyu Meng,Luyan Zhang,Luyan Zhang,Xin Lv,Xin Lv,Sarangerel Davaasambuu,Qiu Guanzhou,Qiu Guanzhou,Qiu Guanzhou +17 more
TL;DR: In this paper, a method called "sulfuric acid curing" was proposed, aiming to extract rare earth element scandium from silicates, and the effects of sulfuric acid dosage, curing time, curing temperature, pulp density, leaching temperature, and stirring speed were investigated.
Journal ArticleDOI
Reactive oxygen species formation driven by acidophiles mediated pyrite oxidation and its potential role on 2,4-dichlorophenol transformation
TL;DR: In this article, the role of microorganisms on pyrite-induced reactive oxygen species (ROS) generation and 2,4-DCP transformation under oxic and anoxic atmospheres by acidithiobacillus ferrooxidans was explored.
Journal ArticleDOI
Interactions between marmatite and bornite during the oxidative dissolution process in abiotic and biotic systems
Yanjun Zhang,Yanjun Zhang,Hongbo Zhao,Hongbo Zhao,Yisheng Zhang,Yisheng Zhang,Lu Qian,Lu Qian,Luyuan Zhang,Luyuan Zhang,Xiaoyu Meng,Xiaoyu Meng,Xin Lv,Xin Lv,Pillai Abhilash,Hussnain Ahmed Janjua,Guanzhou Qiu,Guanzhou Qiu +17 more
TL;DR: In this article, the authors showed that marmatite can significantly accelerate the oxidative dissolution of bornite, especially in the abiotic system, and that the galvanic interactions between marmatites and bornite were slight and should not be the main cause for the interactions.
