A rock is either crushed or ground, sodium cyanide (in a ppm level) is added to this rock, and gold reacts with the rock and is leached in the solution. A solution containing gold is reacted with activated carbon, activated carbon gets stripped to produce an enriched solution, and gold is plated in an electrowinning cell.

That also means that the majority of igneous rocks are also not reactive with acids. Things like granite or pegmatite still need to be handled manually. As a general rule, you'll find that the practical use of acid to liberate specimens is limited to removing carbonates and metallic oxides while many host rock types will be immune to acid attack.

If your rock meets all of those criteria then it is very likely a pegmatite, or at least something very closely related. It can sometimes be difficult to distinguish between granite and pegmatite, especially when the crystal sizes are around 1 cm in size – the borderline between coarse-grained and very coarse-grained. In these cases, I like to look at the …

Unakite is a stone that forms from the metamorphism of granite. Less resistant minerals within the granite become altered to be transformed into Epidote or replaced completely by Epidote, with the Orthoclase and Quartz remaining. Green Epidote. Epidote crystals typically range between yellowish green to pistachio green in color.

Granite is much harder than gold, but it's far less valuable than gold. Precious metals like gold and silver are softer than most of the items you'll find rockhounding and their more malleable nature can help you set them apart from similar rocks. In 1822, Friedrich Mohs developed a scale to measure a rock's hardness.
