NEW IAO/20-1 gold refining plants model IAO 6 Kg / DAY

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.

Description of the TLF/750 fume scrubber The tower is used to neutralize fumes and remove organic substances. It is built out of polypropylene sheets. A sprayer is installed inside the tower to spray a 1000 mm thick layer of raschig rings. In order to avoid drop dragging, a second 200 mm thick layer of raschig rings has been placed upstream to the sprayer. A neutralization solution container is placed beneath the tower. The solution circulation pump has a capacity of 55 Lts/1' with a head of 6 m. The suction fan has a max capacity of 300 m3/hour. Technical data: • Power supply : three-phase. • Power : 0,95 Kw. • Overall dimensions : 1350x1050x2800 mm (length-width-height). • Loadless weight : 100 kg • Working weight : 380 kg • Capacity : 300 m3/h with 5”contact time QT PRICE TOTAL PRICE TOTAL PACKING 1 € 9.870,00 € 9.870,00 € 535,00
