Cyanide tailings are industrial hazardous solid wastes arising from gold mining industry.
Hundreds of millions of tons of cyanide tailings that contain highly toxic cyanides and …

Since the birth of cyanidation, it has been dominant in the gold extraction industry. Recently,
with the increasing awareness of environmental hazards and potential risks posed by the …

Given that mining is considered to be an essential activity for Mexico's industrial
development, cyanide has been increasingly used to recover precious metals such as gold …

Abstract In this study, Me (Mn, Fe)-N co-doping is used to improve the treatment efficiency of
TiO 2/SiO 2 on cyanide wastewater, and to explore the reasons for the change in the …

Photocatalytic oxidation can effectively treat cyanide wastewater generated from cyanide
plating and gold cyanidation extraction process. In this study, monodisperse SiO 2 …

Mining industry has been using cyanide for more than ten decades to recover precious
metals such as gold and silver. The presence of cyanide in the environment has long been a …

Heap bioleaching is a microbial technology that catalyzes the decomposition of ore without
grinding. The crushed ore is stacked on the liner, and the microbial solution flows through …

Wastewater streams generated during the leaching process of precious metals recovery (eg
gold, silver) contain high concentrations of toxic compounds, being free cyanide (CN−) one …

Sulfide at mine tailing ponds poses a source of contamination to the surrounding
environment. This study was designed to investigate and assess the fresh and weathered …

Coke-oven wastewater is generally characterized by having an array of pollutants such as
cyanide, phenol, and ammoniacal-N. The present study focuses on the simultaneous …
