There are several ways that mercury is utilized by artisanal small-scale miners (ASGM). It may be mixed with concentrated ore through panning or added to sluices, ball mills or trommels in a process known as whole-ore amalgamation. The resulting amalgam of mercury/gold is called a prill, and it is roasted with a torch or over an open fire.
Gold concentrators are designed to focus on finding fine gold particles that would otherwise be missed. However, the particles of gold can be so fine that it resembles dust, making it difficult for it to be extracted via ways other than with gold concentrators.
