Since gold is much denser than the host rock (19.3 g/cm³ vs 2.5-3.0 g/cm³), the heavy gold particles sink into the table's ridges while the lighter waste washes off. Other gravity methods like spirals and centrifugal concentrators also exploit this density difference between gold (19.3 g/cm³) and the rock (2.5-3.0 g/cm³) to separate the ...

After the gold ore has been removed from the earth using mining equipment, it is sent to a gold processing plant. The typical gold processing plant begins with a cone crusher, to reduce the particle size of the ore. Next, it is loaded on a conveyor belt, where an overbelt magnet removes tramp metal from the gold mining process.

The main advantage of the AARL process is the ability to strip a batch of carbon to low gold residuals in an average strip time of 6–8 hours compared with 6–10 hours for standard Zadra. New plants can be designed with multiple daily stripping cycles in mind, or existing plants can have increased daily capacity by adding shifts for stripping.
