This Stamp Mill dates back to the 1800 s. It has been used at several mines in the Dahlonega area as well as in other states. It was placed on the site in the 1960 s. This Stamp Mill has ten stamps with each one weighing 450 lbs. each. The purpose of the Stamp Mill is to crush gold bearing rock into sand so that it can be processed.

Read MoreJun 14 2018 · Placer mining and lode mining are very different. Whereas placer gold has been released from within the rock and is generally free from any significant matrix lode gold presents different challenges. While gold may be present in ore it must somehow be released for proper extraction
Read MoreThe process plant normally operates continually except during maintenance shutdowns. As for most gold mines the process of gold and silver extraction from the ore is relatively simple the main steps being -Crushing and stockpiling of ore.-Grinding and conversion of ore to form a slurry.-Leaching of gold and silver from the slurry using cyanide.
