| Abstract: |
| Based on the existing silver electrolysis process with reference to the plant practice of high current density electrolysis of copper in Guixi Smelter, a novel high current density(700 A/m2) electrolysis of silver is investigated. The optimum electrolyte components, electrolytic temperature control pattern, electrolyte self-purification process, electrolyte loop control mode, stirring and other key technologies are determined. Furthermore, a novel silver electrolysis cell suitable for the production of high current density is designed. The novel high current density electrolysis of silver with proprietary intellectual property rights is developed. Current density in the novel process is increased from 350 A/m2 to 700 A/m2. |
