Removing the gold bearing rock from the ground is just the first step.
Because raw gold is a natural substance found in nature it is not pure gold but rather a high gold content precious metal alloy.

The acid based vinegar slowly dissolves the quartz crystals surrounding the gold leaving only bits of quartz attached to the gold.
Placer gold is raw gold you find for example as flakes or nuggets in stream beds or on the ground compared to lode gold which are the embedded veins of gold that must be extracted from rock outcroppings.
Most of the gold that is mined around the world is found in lode sources also known as hard rock deposits.
At a mill large machines known as crushers reduce the ore to pieces no larger than road gravel.
What does gold ore really look like.
Take a rock that contains gold in it this process works best on quartz rocks and set it inside a glass jar.
Much of the gold mined is actually from gold ore rather then actual gold specimens.
This is where the gold is actually encased within rocks and must me manually removed from the earth to extract the gold.
