All the best plants for the aqua regia gold refining, from the static refining plant to aqua regia gold refining tumbler - 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.

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.

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.
