It is true that once you get to processing large enough amounts of ore you are likely to need environmental permits, etc., depending on the location you are working in. Most prospectors will choose to stay small, but even on a small scale, you can be processing gold-quartz ores recovering some very good gold and getting into real hard rock mining.
Oct 15, 2016· 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.
