Aqua regia gold Refining Tumbler is a new technology compared to the static refining plants.
It is mainly a total different way to work. The static refining unit is an handicraft way to refine, the “Tumbler Machine” is an industrial way to refine.
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.
