gold refining mercury amalgamator
Amalgamation is a process mainly used for refining of gold, silver. When clean mercury is brought into contact with clean gold, the gold is wetted and “drawn into” the mercury. This results in a solution of gold in mercury or an alloy of gold and mercury called amalgam. After the mercury has gathered in the gold it can be removed by dissolving it in nitric acid or by driving it off as a vapor by heat, leaving the gold will behind. This method yields a high recovery rate, generally over 98%, and a low loss rate of mercury. The mercury can then be reused to reduce operating costs.
Please note that when working with mercury, special health and safety precautions are necessary. It is recommended to read all technical data sheets and material safety data sheets available before proceeding.
The working principle of a gold amalgamator is fairly simple. A cylindrical stainless iron tank is partially filled with gold and mercury and then rotated about its horizontal axis by a motor. In most setups, steel balls are added to the cylinder to further separate the gold from gangue minerals. The stainless iron tank has a long service life and assists in saving mercury. This simple machine is easy to install, relocate and also has low maintenance costs. The quantity and size of steel balls required vary proportionally to the input material size and gold content. For example, when processing a coarse concentrate with high gangue mineral contamination, more steel balls are required. Similarly, if the heavy sand ore concentrate is reasonably fine with no film over the gold particles, then a small quantity of steel balls is required
