All the best plants for the pre-refining and chemical refining of precious metals, chemical refining of gold, silver and platinum - Italimpianti Orafi

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.

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.

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.

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.

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.
