Artisanal small-scale gold miners (ASM) occasionally employ whole ore amalgamation by adding mercury into ball mills to recover gold. In this process, 25–30% of the mercury added is lost to the environment. It is also inefficient less than 30% of gold is recovered. Amalgamation, followed by cyanidation, has been observed.

Heating the mixture . often in a single day. artisanal and Small-Scale gold Mining (aSgM) in developing countries is the largest use . There are simple and effective alternative practices that can be implemented immediately to substantially reduce.
viable alternative to mercury amalgamation is cyanidation. Recently, this substitute was effectively introduced to an artisanal gold mining operation in Portovelo, Ecuador (Veiga et al., 2009). However, economic and technical constraints limit the feasibility of this technology in the majority of artisanal and small-scale gold.
