The units are used to refine gold alloys using aqua regia; minimum obtainable purity is 999.5/1000.
- The units are modular to reduce eventual costs if production increases;
- A vacuum system is used to transfer the acid solutions
- Pyrex glass is used as it is the only material that doesn’t absorb precious metals. It also facilitates the cleaning operations of the reactors and condensers.
- For safety reasons, all parts in pyrex (reactors and condensers) are positioned inside a ppl hood fitted with a suction manifold that can be connected to a fume scrubber, our model TLF/750. The hood has been designed to recover any acid or water leakage.
- The electric heaters for the reactors are fitted with power regulators to control the dissolution process.
- The units are supplied with two containers for HCL and HNO3 positioned in a PPL tray as requested by European laws. The acids are transferred from the storage containers to 2 graduated pyrex containers inside the hood by a vacuum system. From there, they are transferred to the reactors by gravity.
- Filter unit on wheels with a compressed air diaphragm pump to transfer the solutions;
- Cementation tank
- Every unit is supplied with two storage containers on wheels for the king waters as well as a control panel.
