    Mercury in Artisanal Gold Mining. In many countries, mercury is used in artisanal and small-scale gold mining as it is a cheaper option than cyanide and is readily available. It is estimated that there are approximately 15 million artisanal miners globally producing approximately 20 of the world’s gold. This accounts for around 40 of global.Of those methods, the Cyanide Leaching Process Cyanidation, is the method that is commonly used the most often to do this.

    Abstract. Highly toxic sodium cyanide (NaCN) is used by the international mining community to extract gold and other precious metals through milling of high-grade ores and heap leaching of low-grade ores (Korte et al. 2000). The process to concentrate gold using cyanide was developed in Scotland in 1887 and was used almost immediately in the.The Clean Mining gold recovery process, developed by Australia’s CSIRO, replaces cyanide and mercury with a safer, less hazardous chemical reagent. This alternative gold recovery solution is non-toxic and dissolves fine gold out of ores into a solution, which can then be.
