We provide our clients with the best possible service in terms of quality, speed and cost-effectiveness while complying with environmental laws by employing the most advanced available technologies and using only sworn essayers, trained and supervised by the Swiss central office for the control of precious metals.
We are able to process and refine metals from both primary and secondary sources, as well as creating custom solutions for our clients sourcing needs, including dedicated, traceable production lines.
The metals
we process:
Gold
Our gold exceeds LBMA's
Good Delivery standards
(995.00) by achieving the
so-called 4 nine fineness
(999.9 parts per
thousand). For special
applications, such as the
electronics industry, our
technologies enable us to
achieve the exceptional
Five nine purity level
(999.99 parts per
thousand).
We only process material
in a metal form from
mines, industrial scrap or
recycled gold, sourced
from operators who can
pass our strict "know your
customer" assessments.

Silver
Like gold, our silver also
exceeds LBMA‘s standards
(999.0) by achieving a
purity of 999.9 parts per
thousand. We only
process material in a
metal form from mines,
industrial scrap or
recycled silver, from
operators who can pass
our strict ‘know your
customer’ assessments.

Platinum
Refined to a purity of
999.5, all platinum
processed by
Argor-Heraeus comes
exclusively from recycled
sources.

Palladium
Like platinum, palladium
refined by Argor-Heraeus
reaches a purity level of
999.5. It is also not
obtained from mining
activities but only from
recycled sources.
