Chemical refining plants



The most effective yet simple process to refine gold from metal alloys, is by means of Acqua Regia solution, a mixture of appropriately calibrated hydrochloric and nitric acid, which has been widely employed in diverse sectors (goldsmith, mining, WEEE, galvanic, etc.) as of today.

Our machines are made as a monoblock for greater compactness: the vapour reduction tower is on the back, while the frontal working area allows easy accessible to all its components, while maintaining high safety standards both for the operator and the environment.

The standard systems yield from 1Kg, up to 25Kg, but modular systems equipped with reactors can yield up to 300Kg per working shift. All our systems are guaranteed with a warranty and immediate technical assistance. Our machinery can also be designed specifically for the treatment and purification of metal alloys containing platinum, palladium, rhodium, ruthenium and other metals. The resulting final purity of the target metals is always equal to or greater than 99.95%.




B.T.T. Italy has been building special systems for 40 years aimed at performing this process in a speedy and efficient focusing mainly in the separation of gold and silver.

Our equipment guarantees obtaining a pure gold powder with a title equal to or greater than 99.99% guaranteed in just single step.
