A review on the negative impact of different elements

The ongoing depletion of gold and silvercontaining ore deposits demands a shift towards the processing of more complex sources. Leaching of gold or silver from these sources, which are named refractory and are typically lowgrade, can be complicated due to one or more of the following effects (1) kinetic or thermodynamic impediments on cyanide diffusion or on the dissolution of minerals, (2
