It has the ability to collect unliberated gold that remains trapped/attached to rock as well as the super fine gold particulate that escapes when mercury amalgam is squeezed and condensed. Field experiments conducted in 2009 showed that the mercury method recovers about 88% of gold, whereas direct smelting yielded recoveries of 95%.

Crushing. Once gold-rich ore is excavated, it needs to be crushed into a fine powder before it can be processed. The initial crushing is done by hand with makeshift hammers, almost exclusively by women. Ball mills- tumblers full of steel balls- complete the final stage of crushing, producing finely ground ore-powder.
