【摘要】 在现有银电解工艺的基础上,借鉴贵溪冶炼厂高电流密度铜电解生产经验,通过试验研究,确定了高电流密度(700A/m2)电解条件下电解液最佳组分、净化工艺、循环控制模式、搅拌方式等关键技术,自行设计出适合高电流密度生产的银电解槽,开发出具有自主知识产权的高电流密度银电解新工艺,电流密度由原来的350A/m2提高至700A/m2。更多还原

【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.更多还原
