Aqua Regia Gold Refining Tumbler

Aqua regia gold Refining Tumbler is a new technology compared to the static refining plants.

It is mainly a total different way to work. The static refining unit is an handicraft way to refine, the “Tumbler Machine” is an industrial way to refine.

This refining system consists of a cylinder made of polypropylene having an inclination of about 25° and it continuously rotates by means of a special motor, with the possibility to adjust also the speed rotation.

This continuous rotation allows a very good rubbing of the gold grains and consequently a quick and proper dissolution of them.
the “ Tumbler “ is equipped with a Pyrex glass condenser with a cool water circulation that allows a good acids recovery and a good fumes neutralization.

Another big advantage is that it can work also in the night without any workers’ supervision.

It is a polyvalent unit as it allows to refine the gold grains as well as the casting scraps and some types of precious ashes.

The plant is mainly made up of:

  • Nr. 1 Polypropylene hood containing with suction fan to be connected to a fume scrubber designed to recover any acid losses.
  • Nr. 1 Cylinder made of polypropylene with a useful capacity of about 100 litres (acids plus gold grains), this cylinder is inclined of 25° and it continuously rotates by means of a special motor, with the possibility to adjust also the speed rotation.
  • No. 2 Graduated tanks for HCl and HNO3. Acid transfer from the reactors by vacuum.
  • No. 1 Polypropylene tray with containers for HCl and HNO3 acids.
  • No. 1 Filter Trolley with a compressed air diaphragm pump to transfer the solutions.
  • No. 1 Cementation Unit for gold precipitation.
  • No. 1 Electrical board.

The above system can be customized upon request of the customer, the photos submitted are just one example of the many possible system solutions.

Based on the needs of the customer is possible to create customized systems, with suitable characteristics for the process requirements.
