ProductContent Electrolysis (electrowinning) non-ferrous metals
Electrolytic extraction of non-ferrous metals including
electrolytic extraction of metals and sulfate solution mixed
chloride sulfate liquid electrolytic extraction of metals melt. 1,
the electrolytic extraction of metal chloride solution Chloride
melt liquid metal electrowinning, factories in the past using
graphite anode, graphite resistance large, so power consumption,
low strength of graphite anode, easy loss, working life is short,
graphite cathode product contamination, it is difficult to obtain
high purity metal. Chloride electrolyte solution, electrowinning
metals, precipitation of chlorine on the anode, the most important
characteristics of active coating over potential of low chlorine,
conductivity and good resistance to chloride corrosion, anode and
long service life. 2, the electrolytic extraction of metal sulfate
solution Electrodeposition of metal sulfate solution commonly used
lead-silver anodes, but in the electrolysis process, the
lead-silver anode will dissolve both the anode material
consumption, but also affect the working life of the anode, and
lead dissolved in the solution will be precipitated on the cathode,
impurities in the metal content of lead increased, reducing the
product quality. Sulfate electrowinning metals, mainly produce
oxygen on the anode, coated titanium electrode active coating of
the most important feature is the point of oxygen catalytic
activity, conductivity, and on the oxygen durability, long life
anode, and anode conductive properties, compared with lead-silver
anode, cell voltage can be reduced 0.5V, to produce 1 ton of
finished products, energy-saving rate of *7%. 3, the chloride
electrolytic extraction of metal sulphate mixture Sulfate-chloride
electrolyte mixed system, the anode and simultaneous deposition of
chlorine and oxygen, a very serious corrosion of the anode, the
anode is more work under harsh conditions, according to my
experience is the product produced by the actual running
performance tests, add in the active coating active elements,
titanium anodes in the reaction favor the release of chlorine and
oxygen inhibition of the reaction, and can extend the working life
of the anode. Electrolytic extraction of metals using insoluble
anode, so that by the leaching, purification of the electrolyte in
the extraction of metal ions in the cathode to be far, a system of
pure metal. Electrowinning In the hydrometallurgy industry already
accounts for a large proportion. Non-ferrous metallurgical
production by electrolysis has Zn, Cd, Cu, Mn, Co, Cr, Ni and so
on. Cathode electrolytic extraction using two. One is the beginning
of reusable pole piece. When the metal pole piece in which the
beginning of the deposition to a certain thickness (eg **3mm), the
sediment layer is about stripping, and the beginning of a pole
piece is used again. For example, the electrolytic extraction of
zinc, the use of aluminum for the beginning of a pole piece;
extraction of cobalt, the use of stainless steel; extraction of
copper, the use of titanium. Another one-off kind of cathode plate,
when the same kinds of metal deposited on its removal to a certain
thickness after melting. In recent years, coated titanium electrode
in the electrodeposition of metal areas have been widely used,
stable quality, light weight, corrosion resistance, long life, very
pitch stable, increase the current density, lower cell voltage,
energy efficiency, size, flexible, customized according to user
requirements, all aspects are indicative of the superiority of the
titanium electrode.
