Cyanide still has an important role in gold mining and when used will always be a risk. Though Mudd believes: “Cyanide can be managedHowever, it does require a lot of due diligence and careful attention.”. “Using best practices and auditing is the best thing and mining companies are doing that,” agrees Blackmore.Mercury amalgamation is the method of choice to recover gold in artisanal and small-scale gold mining (ASGM). However, despite the low cost and simplicity of this method, the use of mercury presents serious health and environmental risks, as well as low efficiency in gold extraction.
