PLATINUM/RHODIUM REFINING PLANT
TYPE IAP/50Pt
Description
The unit is used to refine Pt & Rh alloys. The same plant can also be used for separating and refining Au, Pd, Ag, if these metals are present in the alloy.
A quantity of silver above 8-10 % hinders the refining process.
If more than 0.5 % of Au is contained in the alloy, it must be precipitated first.
Pt refining
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 (optional). 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 unit for precipitation phase
o Every unit is supplied with one storage container on wheels for the king waters storage.
The dissolution is carried out using the aqua regia process. The sequence of operation proceeds as follows:
- Silver separation
- Gold separation
- Separation of all other metals
- Precipitation of solution to recover the Platinum
Rh refining (lab equipment)
This equipment is sufficient to refine Rh. This equipment consists of :
- Tube furnace
- Rh refining glassware (lab equipment)
- Required accessories
- Dedicated TLF/500 fume scrubber
- Final purity : 999/1000
- Iridium (Ir) and rhodium (Rh) are separated and recovered in powder form
Please take note that refining Rhodium is a very complicated and highly technical operation and requires a degree in chemistry (MSE or BSE) to be carried out in the proper fashion. We strongly advise against such a job being carried out by a non-chemist.

NEUTRALIZATION TOWER FOR FUMES MODEL TLF/850
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 1300 mm thick layer of raschig rings.
In order to avoid drop dragging, a second 310 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 2000 m3/hour.
Technical data:
• Power supply : three-phase.
• Power : 3 kW
• Overall dimensions : 1500x1200x3500 mm (length-width-height).
• Working weight : 350 kg
