RETEC Electrolytic Cells
Application field
The RETEC Electrolytic cells have been used
for metal recovery since more than 20 years.
RETEC – cells are ideally suited for the
recovery of gold, silver, copper, cadmium and
nickel. The systems are simply designed,
inexpensive and highly efficient.
RETEC – cells can be installed for example
next to a rinsing bath in order to reduce
continuously the content of metal ions.
Process Characteristics
The metal ions present in the solution are
reduced and deposited as metal on the
surface of foamed cathodes which are made
either of copper or of nickel.
The cathode offers a very large effective
surface. It enables an effective elimination of
dissolved metal ions, even at a very low
concentration (a few ppms).
When one of the cell cathodes is fully charged
with metal, the metallised cathode may either
be sold for the metal value or used as an
anode in a recycling unit.
The Anodes are available in different qualities
and consist of a titanium mesh covered with a
noble-metal catalyst.

Description of plant
RETEC – cells are available in different sizes and can contain from 2 up to 50 cathodes. The systems
are delivered fully equipped with rectifier and easy to install.
The electrolyte is introduced at one end of the cell, passes through the cell and is evacuated through an
overflow at the other end. The dissolved metal in the electrolyte is deposited on the surface of the
cathodes.
Cathodes are available from stock in two different sizes.
Type 1: 18 x 23 cm, Type 2: 46 x 38 cm, each in Cu and Ni version
For pilot testing, Gütling provides the customers with rental units which allow checking of system
functionality and efficiency.
