Recycled metal titanium anode

Application of electrolytic extraction of metal titanium anode:

Electrolytic extraction of metal using insoluble titanium anode, so that after leaching, purification of the electrolyte to be extracted metal ions far away from the cathode, to produce pure metal. Electrolytic metallurgy has a large proportion in the hydrometallurgical industry. Nonferrous metals produced by electrolytic metallurgy include Zn, Cd, Cu, Mn, Co, Cr, Ni, iN and so on.

Electrolytic metallurgy has the advantages of high selectivity, can obtain high purity metal, can recover useful metal, so it can deal with low-grade minerals and complex components of polymetallic ore, conducive to the comprehensive utilization of resources. The extraction of copper is a typical example. Due to the depletion of high-quality copper resources, the smelting of low-grade copper ores is paid more attention. Electrolytic extraction is generally adopted. In addition, less pollution to the environment, production is easier to continuous and automatic, but high energy consumption. At present, energy saving is a very important research topic of electrolytic metallurgy.

There are two kinds of cathodes used for electrolytic extraction. One is a reusable starter plate. After the metal has been deposited to a certain thickness (e.g., 2-3mm) on this electrode sheet, the deposit layer is stripped away and the electrode sheet is used again. For example, when zinc is extracted electrolytically, aluminum plate is used as the starting plate; When extracting cobalt, stainless steel is used; When extracting copper, titanium plates are used. The other cathode is a disposable seed plate, which is removed and smelted after the same metal has been deposited on it to a certain thickness.

Electrolytic extraction of metals can be carried out in chloride electrolyte, sulfate electrolyte, and chloride sulfate mixed electrolyte.

In recent years, coated titanium electrode has been widely used in the field of electrodeposition metal, stable quality, light weight, good corrosion resistance, long life, stable pole spacing, improve current density, reduce groove pressure, energy saving and efficiency, flexible size, can be customized according to user requirements, from all aspects show the superior performance of titanium electrode.
