Gold, Mercury, and Silver Extraction by Chemical and

Experiments results showed that at the optimum condition gold recovery was 91.8% and silver, and mercury recoveries were 41.5%, and 10.2%, respectively. After performing cyanidation tests for 6 different fractions, it was concluded that the most unleached gold particles exist in the fraction size finer than 25 μm and about 5% of gold particles in the fraction size larger than 25 μm was not leached.
