Gold Processing Steps 101: Essential Guide
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 ...
