Extracting gold using borax? Can someone explain? | Gold Refining
I can see it being used for the crucible and maybe putting it in the bath water to help keep the gold from floating away. Other than that, it's probably a Borax commercial.

How To Refine A Gold Smelt
In nature, gold nuggets are not pure gold. They are a combination of minerals, known as ore. The metal can be removed from the ore in a process known as smelting, in which the minerals are separated by melting point. Smelt gold is more pure than the original ore product, but can still contain impurities such as sliver, copper and platinum.

will ferrous sulphate drop the gold???
Scott, You are correct that it is the iron in the copperas that precipitates the gold, here is something else to consider, if you have gold and platinum in solution, ferrous sulfate will precipitate the gold but not the platinum (platinum is below iron in the reactivity series), if we added a bar of elemental iron to the solution of gold and platinum, the iron would give up …
