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
Study on Influence Factors of Leaching of Rare Earth Elements from Coal Fly Ash
Shanshan Cao,Changchun Zhou,Jinhe Pan,Cheng Liu,Mengcheng Tang,Wanshun Ji,Tingting Hu,Ningning Zhang +7 more
TL;DR: In this paper, the effects of various factors on the leaching efficiencies of rare earth elements (REEs) from coal fly ash (CFA) were investigated systematically, and two unreacted core shrinkage models (chemically controlled model and diffusion controlled model) were used to study the leach kinetics of REEs from CFA, except for the small influence of the stirring speed, the temperature, acid concentr...

Modes of Occurrence of Rare Earth Elements in Coal Fly Ash: A Case Study
Jinhe Pan,Changchun Zhou,Cheng Liu,Mengcheng Tang,Shanshan Cao,Tingting Hu,Wanshun Ji,Yulin Luo,Mingzhong Wen,Ningning Zhang +9 more
TL;DR: In this paper, coal fly ash (CFA), the main byproduct of coal combustion, has been regarded as an attractive source of rare earth elements plus yttrium (REY).
Journal ArticleDOI
Effects of particle size on flotation parameters in the separation of diaspore and kaolinite
Ningning Zhang,Changchun Zhou,Cheng Liu,Jinhe Pan,Mengcheng Tang,Shanshan Cao,Chang-Heng Ouyang,Chang-Bin Peng +7 more
TL;DR: In this paper, the effect of particle size on flotation parameters in the separation of diaspore and kaolinite was examined and the results showed that the particle size has a significant influence on the flotation parameter.
