Gold emptying plant

The emptying process of the golden and Silver objects, chains, earings, links or hollow reed can be made by using different types of reagents like Nitric acid, hydrochloric acid, and caustic soda.

The Nitric acid is used when the core of the reed is in copper or tombak; the hydrochloric acid is used when the core is in iron and the caustic soda is used when the core is in aluminium.

It is obvious that for every kind of reaction the specific materials and the specific machine are necessary.

The following photos show the necessary machines for the different operations.

We want to underline that the models are susceptible of change (the production capacity) depending on the customer demand, maintaining the safety characteristics in accordance with the law in force.
