on the Micro-mechanism of Precious Metals Trapped inPyro-metallurgical Processes by Base Metals and Matte

Chen Jing

Strategic Study of CAE 2007, Volume 9, Issue 5,   Pages 11-16

Abstract: melted slag phases possessing very different structure and properties from that the melted base metal or mattepresent the negative values, its conductance belongs to the electron conductance .The properties of the mattesimilar with that of metal at their melted state, therefore precious metal atomswill enter into the mattephase, but not the slag phase in matte-smelting process .

Effective enrichment of Zn from smelting wastewater via an integrated Fe coagulation and hematite precipitation

Zhan Qu, Ting Su, Yu Chen, Xue Lin, Yang Yu, Suiyi Zhu, Xinfeng Xie, Mingxin Huo

Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 6, doi: 10.1007/s11783-019-1178-4

Abstract: 98.5% Zn was enriched from Zn-bearing smelting wastewater. 99.5% Fe was hydrothermally precipitatedThe residual Zn was 2169 mg/L, 290 times of that in smelting wastewater.Coagulation is commonly applied to treat Zn-bearing wastewater from smelting industries (smelting wastewaterHerein, we demonstrated a novel approach to recycle Zn effectively from smelting wastewater via an integratedFirst, smelting wastewater was coagulated by adding ferric chloride to generate Fe/Zn-bearing sludge
