Aqua regia gold refining tumbler

This refining system consists of a large PPl cylinder inclined to an angle of 25°, it continuously rotates by means of a special motor, with the possibility to adjust the rotation speed.  The rotation forces the grains to rub against each other and consequently a rapid and effcient dissolution process is induced.

A Pyrex glass condenser is positioned externally to the tumbler  with cold water circulating inside that allows for partial acid recovery and initial fume neutralization. 

Another advantage is that it can work throughout the night without supervision.

Candle filters for precious metals/catalysts filtration

Candle Filters work on the basis of pressure. The fluid to be filtered is forced through a vertical filter (candle). The solids in the fluid being filtered cakes on the filter candles until flow is decreased and pressure starts building. At that point, a pulsed air or nitrogen (gas) in reversed flow, causes a rapid deflection of the filter cloth of the candle and the immediate detachment of the cake, where they drop to the bottom and fall out of the filter.

Ef-zero - eco-friendly gold refining system "zero emission"

The EFZERO gold refining plants, produced by Italimpianti Orafi, can refine all kind of gold alloys without development of any sort of acid fumes and with recovery of nitric acid.

Electrolytic copper refining plant

Copper electrorefining entails electrochemically dissolving copper from impure copper anodes into an electrolyte containing CuSO4 and H2SO4, and selectively electroplating pure copper from this electrolyte without the anode impurities.

It produces copper essentially free of impurities, and separates valuable impurities such as gold and silver from copper for recover as by products.

Electrolytic gold refining plant type iao/a

With these refining plants, it is possible to obtain gold with a purity of 999,9/1000 starting from 900/1000 with a maximum silver content of 3 % and total PGM 0,1 % max.

 

Electrolytic silver refining plants aff/ag

The plant consists of modular units that allow the production of the very purest silver. Each tank can refine from 15 to 35 kg per day. Fast collection of the pure silver crystals discharged from the tanks. Fume extraction hood which allows easy installation of the anodes.
Electrolyte recycling pump which prevents unwanted deposits of silver on the anodes. Current rectifier with electronic voltage stabiliser.

Electrowinning plant (gold, silver, copper, nickel)

This plant can refine silver coming from silver nitrate solutions getting a final purity of 999,0/1000.

Filter trolleys

This equipment is designed for the filtration of liquid solutions containing solid/powder.

Iao/br tita - titanium gold refining tumbler

The titanium refining tumbler is a new versatile, durable, and heavy-duty unit for the dissolution of precious metal alloys.

This is an innovative system that allows precious metal alloys to be refined with both aqua regia and inquartation.

Laboratory hood type c-lab/b1

It is made out of self-extinguishing polypropylene (PPS) , with a transparent PVC protective door and complete with:


- Wash-basin with collection tank and storage container to drain solutions and acids
- Electrical heating plate with adjustable power
- N° 1 filtration flask and vacuum system with dedicated valve
- N° 1 tap for demineralized water
- Accessories (Graduated flask, buchner filter, various beakers, filter papers, anti-acid gloves ...)

 

These laboratory hoods are suitable for the extraction of gases, fumes and dusts, including toxic, corrosive or acidic, in processes such as mixing, pouring and packaging of chemical substances. They are recommended for use in laboratories and chemical industries.

They are also used for the treatment of modest quantities of precious metals, such as waste and processing residues from refining and incineration processes.

Pre-refining unit for low karat gold alloys (inquartation method)

The plant of inquartation consists of a reactor by stainless steel or Pyrex glass, provided with a heating system (direct or indirect). The reaction time is comprised between 3-6 hours and the controlled addition of nitric acid helps to reduce the amount of nitrous vapors (NOx) developed.

Refining plant type aff/pt

The plant is used to refine alloys containing platinum, palladium and rhodium by aqua regia method. The maximum quantity with this plant is 1-2-5 kg / cycle. The cycle time is 3 days of 8 working hours and the fineness of platinum and palladium refined obtained is 999.5 / 1000.

Resin unit

The unit contains a series of selective resins to recover a wide range of pms from acidic solutions coming from aqua regia refining processes after cementation.

Silver nitrate salt production unit

Silver Nitrate Salt Production process is carried out by the following steps:
A) Silver Dissolution by Nitric Acid
B) Nitrate solution Filtration
C) Concentration of the silver nitrate solution
D) Crystallization of the solution
E) Drying of the Salt
By using this method you can get a final purity of Silver Nit

Silver refining chemical plants

The refining process is chemical and is realized by a specific and rigorous procedure that uses base chemical reagents with low-pollution impact. The cylindrical reactor with agitator is appropriately designed to allow perfect homogenization during the conduct of the process and ensure a complete reaction.

Static glass refining plant

The aqua regia refining process is used to refine gold alloys using a combination of acids and chemical products. The aqua regia solution consists of a mixture of hydrochloric acid HCL and nitric acid HNO3.

Vacuum generator

Vacuum generator based on the Venturi principle with high efficiency injector, consisting of solution containment tank and high-pressure centrifuge pump
