Borax was added to milled ore to reduce the melting point of gold to a level accessible to SSM. The amount of gold captured, and the amount of mercury released into the environment, was compared to two common amalgamation methods: whole ore and heavy metal. Discussion. The borax method appears to capture more gold, as well as eliminate the use ...

The Borax Method is a technique of artisanal gold mining, with its basis in the principle that borax reduces the melting point of all minerals, including precious metals like gold. The melting point of gold is 1063 ˚C, which is a higher temperature than can be obtained by cheap torches and burners. By adding borax to the heavy mineral concentrate, the melting point temperature decreases ...

Considering that borax was a well-known flux in period, I think it's reasonable that it was used in the fusion step for smelting silver. 6 For sufficiently pure silver and gold in quartz, amalgamating with mercury was preferred over smelting. Pliny mistakenly believed that amalgamation worked only for refining gold (book XXXIII, sec. XXXII).

A Poor Man's Method of Smelting Gold ... You can remove the most common metals found in gold ore (copper, zinc and lead) using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide, zinc oxide and lead oxide — all of which are less dense than pure gold and will float to the top of your crucible allowing the slag to be sloughed off ...
