Gold Extraction & Recovery Processes
The processing of gold ores has traditionally made use of conventional crushing and grinding circuits.

Jigs are the ...
Dissolving Ore?
This is an alternate method to using AquaRegia. The problem with using acids like this with "gold ore" is that other metals are almost always present in the ore with the gold, so once you dissolve the gold into solution, other metals are also spoiling the mix, which makes removing the gold even harder to do. Sulfuric Acid will "not" dissolve gold.
