Advances in the Cyanidation of Gold - ScienceDirect

2016-1-1  1. Introduction. In the past 25 years, most of the development in the cyanidation of gold has occurred in response to the decreasing grade of deposits, the shift from surface mining to underground mining, the increasing complexity of treatment, and the concern for environmental constraints.Research has focused on the use of new equipment such as the IsaMill to liberate gold finely disseminated ...

Effect of pH on Cyanidation Process -

2021-6-15  Running your CIL at a lower pH the causes the reaction to be more thorough rather than faster at lower pH conditions. What this means is- The lower pH may increase the number of free CN- ions and therefore as the concentration of dissolved CN ions is the main driver of dissolution rate of gold then the lower pH stands to drive the reaction faster or more thoroughly.
