Precious metal semi-finished products

Your precious metal cycle with Heimerle + Meule
Heimerle + Meule develops
and manufactures machinery,
equipment and chemicals for
the on-site recovery by our
customers of precious metals
from drag-out rinses, spent
electroplating baths and diluted stripper solutions.
These products contribute
greatly to the rationalization
of the treatment processes
and pay for themselves
within a very short time.
Our Electroclaim, Ionoclaim
and Rhodoclaim system solutions facilitate the efficient
on-site recovery of precious
metals from precious metal
bearing solutions. The pre-
cious metal concentrates
obtained in this way can then
be professionally refined at
our plant. The option of
exchanging the precious
metal yield for precious metal
solutions and/or other precious metal products from
Heimerle + Meule completes
the precious metal cycle for
our customers.
This precious metal cycle,
with its short routes, minimum
precious metal wastage and
reduced precious metal storage requirements, makes our
customer’s purchasing and
production processes considerably more costeffective.

JUNIOR 120
Pen plating unit
Heimerle + Meule’s own
equipment service centre
offers a comprehensive and
specially designed range of
electroplating units and
systems for one-off and
small-batch processing and
for series production.
Our products are mainly
used in industrial production,
goldsmiths’ and watchmakers’ workshops, schools,
universities, institutes and
laboratories.
24
With this pen plating unit,
gold, silver and rhodium can
be deposited with ease.
The technique is economical
and stain-free. The apparatus
is particularly suitable for
jewellery with complex geometries such as settings,
rings, brooches, necklaces
and watches which would
otherwise have to be masked
– a time-consuming and
expensive procedure. Layers
of approx. 0.1 – 0.2 µm can
be deposited.
JUNIOR 120 is very easy to
operate: Using a pair of
tweezers (cathode), attach
the work to the pen plating
unit. Dip the felt tip of the
plating pen (anode) into the
plating bath. Then apply the
plating solution to the work,
making sure that the tip only
glides over the surface.
When the plating is completed, rinse the plated part
under running water and
dry it.

Electropolishers for gold
and silver
Electropolisher PEG 40
Electropolishing gold and
silver is an efficient and economical way to brighten
jewellery, especially items
with a complex geometry.
This is a benchtop unit suitable for workshops. One item
can be polished per cycle.
The maximum surface of the
workpiece should not exceed
10 – 15 cm2.
This technique can be
employed to brighten almost
all silver and gold alloys
(including centrifugal
castings) with the exception
of white gold/palladium.
Polishing cycles last between
5 – 30 seconds and even
deeper and hidden surfaces
can be successfully polished.
You will find details of the
required polishing salts on
page 20.

Jewellery colours
Design and colour in the highest qualities
®
Colour is once more restored to jewelry.
The playfulness and the romantic reminiscence
of the current designs appear to draw on role
models from Art Nouveau or Art Déco.
Colorit® – the modern art
In addition to traditional enamel techniques,
Red is the colour of love, green is the colour
of hope. Colours touch our moods, inspire,
fascinate us. With Colorit® you transfer this
fascination to your jewellery – with the greatest
of ease and unlimited creativity.
modern materials, Colorit® and Novorit, now
offer designers unlimited possibilities to breathe
a sense of colourful life into their jewelry
creations.
Colorit® is available in various colour shades you
can mix freely according to your personal needs.
Your fantasy and experimentally possibilities are
unlimited. This compound material strengthened
by ceramics hardens under blue light. The material is easy and fast to process, grind, polish. It is
adhesive, shock-resistant and wear-resistant –
the ideal material for high-quality and individual
colour creations.
PhotoPolyStation XS und PhotoPolyStation XL
For easy hardening of Colorit® colours by blue
light the hand light unit PhotoPolyStation XS
suitable for single pieces as well as the light box
PhotoPolyStation XL for an even and complete
hardening of several pieces are available.

Colour in perfection
From The Yellow Cow to
Monochrome Blue: art means
colour and with brilliant
colour effects and really simple application, Novorit Pure
Colour will change your
design into art in a flash.
As an innovative composite
material with a ceramic share
of more than 50%, Novorit
Pure Colour fascinates with high purity and surface
quality. Even thin layers, which you may mix
individually and can handle and apply most easily,
result in highly covering colour shades. The material
is hardened through pressure-heat-processes and is
as perfectly suited for creative use in studios and
manufactures as for industrial applications.
Simple application
Novorit Pure Colour is delivered in handy application
cartridges allowing particularly precise and economical working. The material is protected against
contamination. Air pockets are considerably reduced.
The cartridge can be completely emptied. The Novorit
Link for chemical bond of the colours with the metal
is simply applied with a crayon, too. This way, even
fastidious designs are just a piece of cake.
CreaStation 120
With CreaStation 120 you will obtain perfect depth hardening
of your colours. The design allows both simultaneous
handling of more than one piece and absolute homogeneous
hardening of greater depths: at compact measures of
200 x 290 x 330 mm, the pressure-heat-furnace offers a large
polymerisation space with a capacity of 1.7 l, pressure up to
4.2 bar, and an operation temperature of 120°C. You will
receive surfaces which are free of bubbles, extremely resistant to scratches, shock and wear, and ready for easy and
safe further handling.

Machinery and equipment for precious metal recovery
ELECTRO CLA IM
Electrolytic recovery of
precious metals
This system is eminently
suitable for the recovery of
medium and high precious
metal concentrations in
rinses, spent electroplating
baths and stripper solutions.
Up to 1500 g of gold can
be deposited on the three
special cathodes in the
unit’s electrolytic cell.
These high deposition
rates are due to the highly
efficient current flow in
the recovery cell and to
Heimerle + Meule’s special
cathodes. These features
ensure that even low precious metal concentrations
can recovered almost to the
last milligram.
The components of the
Electroclaim unit – rectifier,
pump and recovery cell –
fit neatly into the compact
housing, and the instruments
and switches are ergonomically arranged on the
console. Thanks to its selfsuction pump and the easily
removable special cathodes,
Electroclaim is particularly
user-friendly. The subsequent
recovery of the pure precious
metal from the special cathodes is carried out professionally and economically at
our own refinery.
IONO CLA IM
Precious metal recovery by
ion exchange
This is an extremely efficient
procedure for the recovery of
low and medium precious
metal concentrations in spent
precious metal baths, static
and running precious metal
drag-out rinses and precious
metal stripper solutions.
The recovery unit Ionoclaim
can handle precious metals
in the form of cyanide, chloride or sulphate compounds.
with the resin beads and to
empty it later, which was an
awkward and time-consuming task. With the BES system
you just change the bags.
The resin in the bag is specially adapted to one type of
precious metal. This maximises the working capacity
of each bag. Bags are available with special resins
for gold, silver, palladium,
ruthenium and iridium.
Thanks to Heimerle + Meule’s
flexible Bag Exchange
System (BES), Ionoclaim
offers considerable advantages in terms of handling
and logistics. It is no longer
necessary to fill the bag

Under ideal conditions*
a 500 litre spent bath with
a rhodium content of only
0.1 grams per litre can yield
a rate of return of up to
200 %. In the case of a higher
rhodium content, your rate
of return can increase to
over 800 %.
R HODO CLA IM
Precious metal recovery by
means of chemical reaction
The Rhodoclaim system
developed by Heimerle +
Meule has revolutionized the
recovery of rhodium from
spent rhodium-bearing baths
and rinses. In the past, rhodium recovery could only be
carried out at the refinery –
with all the expense, time and
effort the transport entailed.
Rhodoclaim has changed all
that. It is a user-friendly and
extremely profitable system
which allows you to recover
the precious metal yourself.
It even makes it possible to
recover rhodium from solutions that have previously
not been recycled at all. By
doing so you reduce pollution
and benefit financially.
How the system works:
Rhodium forms a compound
with the newly-developed
Rhodoclaim powder which
means that you simply add
the powder to the spent solution after adjusting the
pH value – an extremely
simple procedure.
Rhodoclaim system
After filtration and drying you
send the rhodium-bearing
extract to Heimerle + Meule.
In this form, the consignment
doesn’t even have to be
classified as hazardous.
* i.e. a low level of contamination of the bath and
provided that the instructions for use are followed
correctly.
The Rhodoclaim system solution also includes analysis,
professional processing and
the recovery of the rhodium
in our own refinery. In
exchange for the rhodium
extract you send us, you
receive the proceeds of the
recovered rhodium in the
form of a financial settlement,
rhodium baths or other
Heimerle + Meule precious
metal products. If you wish,
we can open a free precious
metal account for you.
