Adsorbing cyanide-solubilized gold onto activated carbon was a critically important development step in gold processing (Nicol et al., 1984a, Nicol et al., 1984b, Nicol and Fleming, 1984c) and played a significant role in expanding gold production. Lime and the consequences of its use, also play an important role in the performance of …
Inasmuch as gold-silver alloys of this composition are almost as soluble in cyanide as gold is, it is probable that some other factor has affected the solubility of the electrum particles. Possibly some other alloying element has influenced their solubility in cyanide. The only compounds of gold found in nature are the gold-silver tellurides.
The acquisition of Cyanco, a sodium cyanide business with plants in Nevada and Texas, will combine with Orica's existing sodium cyanide factory in Queensland to create the biggest producer globally.

ORP change will dictate metal speciation and their uptake profile by both plant species. In general, the seepage showed a slightly alkaline condition (Coudert et al., 2020) which could be induced by the use of calcium hydroxide to control the pH of the ore lixiviation to avoid the formation of cyanide gas during processing (Wadnerkar et al., 2015).
An interesting methodology, using thermodynamic constants and solution analysis, was proposed to explain the deportment of cyanide in gold plant liquors and solids (Adams, 2001). The speciation of cyanide with metals and the formation of thiocyanate are part of the approach. The CyanoStat was the first commercial online …

The consumption of cyanide during processing operations is a major economic cost in the extraction of gold from its ores, while the discharge of cyanide wastes may result in significant environmental pollution. Many factors influence the levels of consumption and discharge of cyanide, including ore mineralogy and lixiviant solution …
Several successful cases in gold plants have been carried out and confirmed the efficiency, economy, and eco-friendliness of these lixiviants (Jie, 2018, Li et al., 2018a, Li et al., …
2.1. Global environmental cyanide. Cyanide is a toxic chemical compound with serious environmental and health impacts. Although cyanide occurs naturally in some plant species and is produced by some industrial processes, it is primarily used in mining operations to extract gold and other precious metals (Rao et al., 2020).Given the high …
