Silver processing It is also the least noble of the precious metals reacting readily with many common reagents such as nitric acid and sulfuric acid Metallic silver can be dissolved from gold alloys of less than 30 percent gold by boiling with 30percentstrength nitric acid in a process referred to as parting
The diagram below gives an overview of the key processes involved in the refining of gold and silver Please note that this is highly simplified and does not detail the many subprocesses involved within each key process the chemical inputs involved in each process as well how the waste outputs from each process are handled Gold Refining Gold mines process ore using various techniques to
In both methods gold and silver is accumulated in the cyanide leach solution The gold and silver bearing liquid called pregnant solution is separated from the ore by various drainage and filtration processes The most common methods to remove the gold and silver involve activated carbon or zinc precipitation
