Partner of the jewellery industry

Heimerle + Meule was

founded in 1845 as a gold

and silver refinery. In 1920

the company diversified

into precious metal alloys

and semi-finished products

for the jewellery and watch-

making industry. Over the

years Heimerle + Meule

developed into a major

supplier of precious metal

dental alloys. Its experience

in the area of precious metal

semi-finished products also

enabled it to take advantage

of the expansion of the

electrical engineering and

electronics sectors where

it enjoys a reputation as a

highly competent supplier.

The acquisition of Pforzheim-

based Heraeus Edelmetall

Halbzeug GmbH in 2001

not only strengthened the

companys precious metal

semi-finished product

division but also broadened

its range to include electro-

plating baths, machinery

and equipment.

Moreover, the acquisition

enabled the companys job

shop to diversify its decor-

ative plating services.

A medium-sized enterprise

with considerable freedom

of manoeuvre,

Heimerle + Meule is part of

the Lbeck-based Possehl

Group. Thanks to its over

200 highly qualified em-

ployees, Heimerle + Meule

enjoys a worldwide

reputation for high quality

standards, expertise and

fairness in all its areas of

activity.

Precious metal semi-finished products

Our aim is to enable you give

free rein to your creativity.

In order to allow jewellery

designers the unhindered free-

dom to turn their ideas into

finished products, we custom-

manufacture a wide range

of coloured and white gold,

platinum, palladium and silver

alloys. It is because our range

is so extensive that we con-

tinually succeed in striking a

balance between cost-effec-

tive fabrication and creativity.

Quality semi-finished products

We offer the following pro-

ducts in accordance with our

customers specifications:

Sheets/strips

Wires/profile wires

Rods/profile rods

Tubes/profile tubes

Ring blanks/profile ring blanks

Creoles/bracelets

Turned parts

Disks

Casting material

Solders

Anodes

This range is supplemented

by solder-backed strips.

As Germanys oldest gold

and silver refinery,

Heimerle + Meule has been

refining precious metal bear-

ing residues for over 160 years.

Our many years of experience

are your guarantee of our abil-

ity to achieve maximum pre-

cious metal recovery rates.

Moreover, our commitment to

the process of continuous

improvement ensures that we

remain cost efficient for the

Competent advice

Heimerle+ Meule attaches

great importance to cus-

tomer relations based on

personal trust.

Our experienced staff will be

happy to advise you on all

aspects of precious metal

recycling. For example, wecan show you how to reduce

costs by optimising batch

compositions, and we can

inform you about packaging

and transport regulations re-

garding hazardous materials

consignments such as pre-

cious metal bearing solutions.

Detoxification and

neutralisation

After recovering the precious

metal, we are required by law

to detoxify and neutralise

electroplating baths, drag-out

rinses and solutions. As a

certified waste management

facility and a specialist

firm as defined in 19i of the

German Water Management

Act, we guarantee environ-

mentally-sound disposal of

these solutions in our

state-of-the-art waste water

Processing and settlement

Even before you send us your

material, we can advise you

on the cost and duration of the

recovery process and the

purchase price. In the case of

financial settlements, you

decide the price fixing date.

Alternatively, you can choose

to receive the proceeds in the

form of precious metal orsemi-finished products. If you

wish, we can credit the pro-

ceeds to your precious metal

account, to which you have

access at any time. A further

option is to transfer precious

metal to other precious metal

processors.

Pre-treatment

The key to a top-quality

coating is the correct pre-

treament of the substrate to

be plated. Heimerle + Meule

supplies bath chemicals

for ultrasonic cleaning and

electrolytic degreasing.

Precious metal electrolytes

for immersion plating and

pen plating


play a vital role in the jewel-

lery industry and goldsmiths

workshops when it comes to

achieving a brilliant finish.

Apart from the basic colours

of the pure metals such

as rhodium, gold, silver,

palladium and platinum,

Heimerle+ Meule can offer

you a host of other gold

shades as well as rhodium

and ruthenium in black.

We not only supply precious

metal electrolytes for immer-

sion plating but also for pen

plating.

Of course, all rhodium, gold

and silver shades match

the colours used in the tank

process.

JUNIOR 120

Pen plating unit

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 geo-

metries 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 m can

be deposited.

JUNIOR 120 is very easy to

operate: Using a pair of

tweezers (cathode), attachthe 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 com-

pleted, rinse the plated part

under running water and

dry it.

Titanium colouring

Titanium in colour

Titanium is a metal that

forms a durable oxide layer

with the ability to refract and

absorb light. By varying the

thickness of the oxide layer,

an array of very decorative

colours can be achieved.

Manufacturers of medical

instruments, spectacle frames

and writing implements have

been benefiting from tita-

niums properties for many

years now. And jewellery

designers, too, derive inspi-

ration from colourful titanium.

A multifunctional material

not only for high-tech

applications

Harder than steel; extremely

resistant to heat, corrosion

and acid; bio-compatible and

exceptionally lightweight:

these properties make tita-

nium and its alloys a material

The TFA 120/10 titanium

anodiser: for durable and

beautiful titanium surfaces

With this titanium colouring

unit from Heimerle + Meule,

existing passive layers can

be reinforced by anodic oxi-

dation. Increasing the voltage

increases the thickness of

the oxide layer. The various

colours will appear at speci-

fic voltage levels.

With a standard 20 litre pro-

cess bath, a 120 V rectifier

by Heimerle+ Meule and the

correct titanium pickle, the

TFA 120/10 enables you to

obtain immaculate shades of

Electropolisher EP 300

With this standard industrial

system, a total surface area

of 80 cm2 can be polished

during each cycle.The chassis is made of square

stainless steel tubing clad

with plastic panels. The

worktop is made of easy-to-

clean plastic. The processing

and rinsing tanks can easily

be changed from the front.

This can be done without

removing the workpiece

holders and cathode rods.

To draw of the vapours from

the bath, an extraction unit is

mounted over the processing

tank and two extractor ducts

are located underneath the

work surface. These are

connected together by means

of flexible pipes at the rear

of the unit.

The controls and displays for

the rectif ier and the thermo-

statically controlled heater

are located on a console

mounted at the rear of the

machine. The rectifier is lo-

cated on the right-hand side

and is easily accessible from

the front for servicing.

An emergency cut-out is

installed to monitor the bathlevel. If the solution drops

below a preset level, the

heater cuts out automatically.

Jewellery colours

Colorit the modern art

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.

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 mate-

rial 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.

Design and color in the highest qualities

Color 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 Dco.

In addition to traditional enamel techniques,

modern materials, Colorit and Novorit, now offer

designers unlimited possibilities to breathe a

sense of colorful life into their jewelry 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 boxPhotoPolyStation 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 sim-

ple application, Novorit Pure

Color will change your design

into art in a flash.

As an innovative composite

material with a ceramic share

of more than 50%, Novorit

Simple application

Novorit Pure Color is delivered in handy application

cartridges allowing particularly precise and economi-

cal 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 120C. You will

receive surfaces which are free of bubbles, extremely resist-

ant to scratches, shock and wear, and ready for easy and

safe further handling.

Pure Color 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.

Machinery and equipment for precious metal recovery

ELECTROCLAIM

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

units electrolytic cell.

These high deposition

rates are due to the highly

efficient current flow in

the recovery cell and to

Heimerle+ Meules special

cathodes. These features

The components of the

Electroclaim unit rectifier,

pump and recovery cell

fit neatly into the compact

housing, and the instruments

and switches are ergo-

nomically arranged on the

console. Thanks to its self-

suction pump and the easily

removable special cathodes,

Electroclaim is particularly

user-friendly. The subsequent

recovery of the pure precious

metal from the special cath-

odes is carried out profes-

sionally and economically at

our own refinery.

with the resin beads and to

empty it later, which was an

awkward and time-consum-

ing task. With the BES system

you just change the bags.

The resin in the bag is spe-

cially adapted to one type of

precious metal. This maxi-

mises the working capacity

of each bag. Bags are avail-

able with special resins

for gold, silver, palladium,

ruthenium and iridium.

IONOCLAIM

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 metaldrag-out rinses and precious

metal stripper solutions.

The recovery unit Ionoclaim

can handle precious metals

in the form of cyanide, chlor-

ide or sulphate compounds.

Thanks to Heimerle + Meules

RHODOCLAIM

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, rho-dium 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 sol-utions 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 sol-

ution after adjusting the

pH value an extremely

simple procedure.

Rhodoclaim system 8101 0 144

includes:

500 or 1000 grams of

Rhodoclaim powder

Folded filters

Measuring spoon

PH paper

Illustrated instructions

for use

Shipping container for extract

Pre-refining precious metal

analysis

Professional refining of the

rhodium

There is a charge of 11.50 for every

gram of reclaimed rhodium

After filtration and drying you

send the rhodium-bearing

extract to Heimerle+ Meule.

In this form, the consignment

doesnt even have to be

classified as hazardous.

The Rhodoclaim system sol-

ution also includes analysis,

professional processing and

the recovery of the rhodium

in our own refinery. Inexchange 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.

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 %.

* i.e. a low level of contami-

nation of the bath and

provided that the instruc-

tions for use are fol lowed

correctly.

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 di-

luted 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 sol-

utions 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 pre-

cious 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 stor-

age requirements, makes our

customers purchasing and

production processes con-

siderably more costeffective.
