Formation, nature and structure of amalgam

In the production process, gold and other minerals in pellet form in contact with the mercury. At this time, other minerals are not trapped by mercury and flow with the slurry, and the gold particles are wetted by mercury to capture (Fig. 1) and diffuse into the interior of the gold particles. The
