Electrolytic extraction of metals is a method of producing pure metals by reducing the metal ions to be extracted from the leached and purified electrolyte at the cathode. Electrolytic metallurgy holds a significant proportion in the field of hydrometallurgy, and the non-ferrous metals produced by electrolytic metallurgy include Zn, Cd, Cu, Mn, Co, Ni, Cr, etc.
The advantages of electrolytic metallurgy:
① High selectivity;
② The obtained metal has high purity;
③ Recyclable all useful metals;
④ Can handle poor ore and various metal deposits;
⑤ Low environmental pollution;
⑥ Production is easy to achieve continuity and automation; The disadvantage of electrolytic extraction of metals is high energy consumption, and energy conservation is a key factor in this process. The performance of the anode material in the electrolytic cell is crucial for energy conservation. The anode requires stability, corrosion resistance, long-term use, and good electrocatalytic activity for the anode process to reduce overvoltage and cell voltage in the anode reaction.
Metal leaching solution includes chloride system, sulfate system, and chloride sulfate mixed system. Different leaching processes have different requirements for anode performance. Specific coating formulas are designed to produce titanium anodes that are suitable for different mineral metal compositions and extraction processes, in order to meet the different needs of customers, maximize the effectiveness of the anode, and save a lot of financial costs for customers
