Journal ArticleDOI
Recovery of rare earth elements from coal fly ash by integrated physical separation and acid leaching.
Jinhe Pan,Jinhe Pan,Tiancheng Nie,Behzad Vaziri Hassas,Mohammad Rezaee,Zhiping Wen,Changchun Zhou +6 more
TL;DR: A conceptual process flowsheet was developed for recovery of REY from CFA which maximizes REY resources utilization and enhances sustainability of CFA disposal.
Journal ArticleDOI
Study on the modes of occurrence of rare earth elements in coal fly ash by statistics and a sequential chemical extraction procedure
Jinhe Pan,Changchun Zhou,Mengcheng Tang,Shanshan Cao,Cheng Liu,Ningning Zhang,Mingzhong Wen,Yulin Luo,Tingting Hu,Wanshun Ji +9 more
TL;DR: In this article, the authors investigated the modes of occurrences of rare earth elements and yttrium (REY) in fly ash and found that the silicate & aluminosilicate form was the dominant mode of occurrence of REY; this form accounted for 80% of the material.
Journal ArticleDOI
Study on extraction of rare earth elements from coal fly ash through alkali fusion – Acid leaching
Mengcheng Tang,Changchun Zhou,Jinhe Pan,Ningning Zhang,Cheng Liu,Shanshan Cao,Tingting Hu,Wanshun Ji +7 more
TL;DR: In this paper, a two-stage hydrometallurgical process (alkali fusion-acid leaching) was developed to recover rare earth elements (REEs) from CFA.
Journal ArticleDOI
XPS analysis of the surface chemistry of sulfuric acid-treated kaolinite and diaspore minerals with flotation reagents
TL;DR: The surface chemistry of acid-treated kaolinite and diaspore in the presence of flotation reagents (sodium hexametaphosphate as a depressant and dodecylamine hydrochloride (DAH) as a collector) using X-ray photoelectron spectroscopy (XPS) analysis and zeta potential determinations was reported in this article.
Journal ArticleDOI
Recovery of Rare Earth Elements from Coal Fly Ash through Sequential Chemical Roasting, Water Leaching, and Acid Leaching Processes
TL;DR: In this article, a sequential chemical roasting, water leaching, and acid leaching process was developed for the recovery of rare earth elements (REEs) from coal fly ash (CFA).
