The mine is an open pit mine.
The gold-bearing rock is scooped out of the ground by large equipment.
It is dumped into trucks that carry a load of 150 tons.
The trucks carry the rock into the mill and dump the rock to be crushed.
Large rock crushers break the rock down into fine pieces.
This is a washing solution that is used to separate the gold.
The gold is melted and poured into bars. The first bar at Fort Knox was poured in December of 1996. The mine produces about 333,000 ounces of gold annually. It employs around 400 people in two shifts, 24 hours a day, 365 days a year. The early miners left behind abandoned machinery and huge areas of rock piles. When Fort Knox is done mining in the area they will be required to do land reclamation. They did fish studies in the area prior to mine construction and they have built a fresh water reservoir that will eventually support fish and game and be operated as a recreational area.
