Alternatives to cyanide in the gold mining industry: what

This paper reviews a series of alternative lixiviant systems for the recovery of gold from ores and concentrates. For over 100 years, cyanide has been the leach reagent of choice in gold mining because of its high gold recoveries, robustness and relatively low costs.

Alternative Gold Treatment Method May Have Applications

2018-8-7  The article explains the new method as follows: This alternative mining method converts the gold-containing ore into chloroauric acid and extracts it using an industrial solvent. The container molecules are able to selectively separate the gold from the solvent without the use of water stripping, which is economically and environmentally costly.

Going for gold: Alternative processing Australian Mining

2014-1-17  Speaking to Paul Breuer at the CSIRO, he told Australian Mining that research is currently developing gold processes using thiosulfate as an alternative lixiviant to cyanide and have made some major breakthroughs. “Gold only forms complexes with certain agents, and thiosulfate is one of the best lixiviants apart from cyanide,” he explained.

Artisanal and Small-Scale Gold Mining Without Mercury US

2021-8-7  In many countries, elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, forming a mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury exposure and health risks.

Mercury-Free Gold mining Technologies

2014-1-23  Technical alternatives for small-scale gold mining, however, must be thoroughly evaluated, pre-tested, modified accordingly and successfully transferred. Moreover, technology must be inexpensive, relatively simple and easy to adapt, while allowing a rapid rate of return. In partnership with the regulatory agencies and other relevant stakeholders of the Guianas, the WWF Guianas program is working towards reducing the environmental footprints caused by small to medium scale mining. The major aspects of this program are to assist in the developing the capacity and regulatory mechanisms, to promote mercury free technology, and monitor mercury in the environment. This technical paper reviews the alternative technologies being investigated by the Guianas for use in the small-scale gold mining
