MEDIUM FREQUENCY INDUCTION MELTING FURNACE FIM/5NT
The furnace is ideal to melt precious metals. All ITALIMPIANTI ORAFI induction melting furnaces are fitted with static frequency converters.
A high efficiency of the electrical output that drastically reduces electricity consumption, maintaining the production rate, is obtained by the frequency conversion system used.
The modular construction of the electric circuit board greatly simplifies maintenance operations and guarantees high reliability even in the most demanding working conditions.
The highest technical standards used to design the inductors along with the modular construction and the use of only high quality materials guarantee maximum production even in the worst conditions.

IAO10-1
Compact Gold Refining Unit
Introduction to Aqua Regia
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. The refining process can be broken down into
several steps:
Refining using Aqua Regia
Best suited for gold with an initial purity of at least 600/1000. Initial purities below
this value can reduce the production capacity as well as increase process times.
Recommended maximum silver content: 10-12 %. Percentages above these values
can reduce production capacity as well as increase process times.
The gold should be either melted into fine grains – using a melting furnace and a
grain tank – or very thin strips.
Strips are ideal due to their large surface area
and complete dissolution when emerged in
the aqua regia solution.
Grains, due to their irregular shape and size,
are more difficult to dissolve and often leave
leftovers in the reactor. On the other hand,
they are quicker to produce than strips.
The IAO10-1 is a new compact all-in-one refining plant is used to refine gold alloys using the aqua regia method
as above-described and especially provided with automatic loading of nitric and hydrochloric acids in order to
speed up the refining process.
Chemical products needed for the Aqua Regia refining method
