Structure and Casting Technology of
Copper Anodes
The anode has to have a certain physical and chemical quality in order to meet the
requirements of electrorefining. Therefore, it is essential to optimise the casting process,
which has a direct influence on anode quality.
Independent of the casting technology used (casting wheel or
Hazelett), proper process control is vital to ensure good anode
quality.
Parameters which influence the quality of casting wheel anodes
are:
-
-
-
Mould material and temperature
Cooling rate (intensity of water-cooling)
Mould wash

The casting process is investigated thoroughly, in order to
determine the optimum structure and elemental distribution
for homogeneous dissolution behaviour of the anode, which
allows the use of higher current densities during electrorefining.
The requirements regarding chemical quality are a homogeneous
chemical composition and elemental distribution, as
well as the formation of solid solutions or soluble compounds
of Cu and the accompanying elements.
A good physical quality is determined by a structure, which
shows good dissolution behaviour and is not susceptible to
passivation.
