PRECIOUS METAL ASSAY LABORATORY

Introduction to Assaying

The assaying process is a necessary step to determine the quantity of precious metals present in an alloy.
Cupellation is one operation of the assay process in which a sample of gold, wrapped in lead foil, is melted in a special crucible known as a cupel: this cupel has the capacity of absorbing the non-precious metals contained in the gold alloy. The weight of the gold alloy sample is usually about 250/1000.
Although this is the most ancient method to determine the purity of an alloy, assaying by means of cupellation gives greater precision than more modern methods (fluorescent or x-ray spectrophotometry) and is considerably less expensive.

Aqua Regia Refining Dept for Au

GOLD REFINING TUMBLER IAOBR1000

More Information On The Aqua Regia Process Click Here

Description

The aqua regia gold refining tumbler is a new technology compared to static refining plants.
This refining unit consists of one PPL tumbler with a total volume of about 1000 litres, inclined to 30° and rotated by a motor, with the possibility to adjust the rotation speed. The rotation forces the gold grains to continuously rub against each other reducing the overall dissolution time. The tumbler has a useful capacity of about 500 litres (acids plus gold grains)
External to the tumbler there is a Pyrex glass condenser to condense the acid fumes reducing their overall volume, thus resulting in a easier fume neutralization operation.
Another advantage is that it can work during the night without supervision.
The daily quantity you can refine every day is 135-140 kg of gold grains with a final gold purity of 999,5/1000 (minimum).
These rotating refining systems can refine gold grains as well as casting scraps and some types of precious ashes.
The plant is made up of :
ƒ N.1 PPL tumbler with a total volume of about 1000 litres
ƒ N. 2 Graduated tanks for HCl and HNO3. Acid transfer from the reactors by vacuum.
ƒ N. 2 Filter units on wheels with a compressed air diaphragm pump to transfer the solutions.
ƒ N. 1 800 litre cementation unit complete with automatic metabisulphite integration system
ƒ N. 1 Electrical board
ƒ External acid storage tanks for HNO3 and HCL
Externally of the “ Tumbler “ there is a Pyrex glass condenser with a cool water circulation that allows a good acids recovery and a good fumes neutralization.
Another big advantage is that it can work also in the night without any workers’ supervision.
