Swirl electrolysis technology uses high-speed rotating flow to eliminate concentration polarization, so high current density can be used to extract metals. In addition, the current efficiency is high at low concentrations and high current densities.
Overview of cyclone electrolysis device and its system The application of cyclone electrolysis technology is completed by a complete device system. The system includes a swirling electrolytic cell, solution distribution system, power system and control system, and engineering supporting systems.
Each swirl electrolysis device uses a DN150mm or DN200mm titanium tube or stainless steel tube as the cathode barrel, and an elastic titanium plate as the cathode electrode is placed in the barrel and is close to the inner wall cathode conductive area of 0.5m2 or 1m2. According to the concentration of metal ions in the solution, appropriate process control conditions are selected to ultimately control the deposited cathode product. The cathode can precipitate metal plates or metal powders. The anode is a titanium-coated anode.
Swirling electrolysis technology is a method to selectively purify valuable metals from solution through the efficient “turbocharge” hardware system using the difference in the precipitation potential of various metal ions. This technology can recover various valuable metals from the solution through a simple single-step process, reduce or eliminate intermediate steps such as chemical purification or solvent extraction to maximize production cost savings.
The principle of cyclone electrolysis technology
Swirl electrolysis technology is based on the difference of the theoretical potential of each metal ion, that is, as long as the metal to be extracted has a large potential difference with other metal ions in the solution system, the metal with the positive potential is easy to be preferentially precipitated at the cathode. The key is to eliminate the disadvantages of electrolysis such as concentration polarization through high-speed swirling. To avoid the influence of various factors such as ion concentration, precipitation potential, concentration polarization, PH value, etc. Simple technical requirements require the production of high-quality metal products. In the electrolytic cell, direct current is used to move the electrons from the anode to the cathode while the metal is deposited on the cathode. The anode reaction loses electrons, so-called oxidation, and the cathode reaction should obtain electrons, so-called reduction reaction.
