Eliminate Mercury using this method of gold extraction with borax for small-scale miners allows for fine gold recovery and better smelting.
We estimate that artisanal and small scale gold mining releases between 640 to 1350 Mg of mercury per annum into the environment, averaging 1000 Mg yr -1, from at least 70 countries. 350 Mg yr -1 of this are directly emitted to the atmosphere while the remainder (650 Mg yr -1) are released into the hydrosphere (rivers, lakes, soils, tailings).
Artisanal and small-scale gold mining (ASGM) is a significant part of the ASM sector and accounts for approximately 20% of global gold supply.

Mercury‐based artisanal and small‐scale gold mining (ASGM) causes more mercury pollution than any other human activity. 1 In this practice, mercury metal is used to extract gold from ore as a stable amalgam. The amalgam is then heated to evaporate the mercury and isolate the gold. While mercury amalgamation has been used for thousands of years to mine gold and silver, 2 it is unfortunately ...
