Free gold is the portion that is easily removed without the use of complex chemical procedures. Miners have been extracting free gold from hard rock sources for thousands of years. It simply requires that the ore be crushed and broken apart enough that the gold can be separated from the host material.

Refractory Gold. The last type of gold deposit is called refractory gold, and it is the most difficult type to extract. It can be defined as any ore that responds poorly to a conventional gravity-cyanidation process with examples including copper porphyry, complex sulfides, arsenopyrite and lead-zinc associations.

Some early miners also used an early form of hardrock mining, digging solid veins of gold out of rock, where mineralized water had deposited it over thousands of years. Today, gold is extracted in hardrock mines that directly mine the source rock, or "lode" of gold, where it was originally deposited by geochemical processes.
