Description

technical field [0001] The invention relates to the technical field of nonferrous metallurgy, and more specifically, to a method and system for measuring electrolysis working conditions in the process of zinc electrolysis. Background technique [0002] Hydrometallurgy is the main method of zinc smelting, and more than 85% of zinc in the world is produced through hydrometallurgy. Electrolysis is the largest energy-consuming process in the zinc hydrometallurgy process, and its electricity consumption accounts for more than 95% of the total electricity consumption in the hydrometallurgy zinc smelting process, and the electricity cost accounts for 30%-40% of the processing cost. Therefore, the energy saving and consumption reduction in the electrolysis process is of great significance to realize the green production of zinc hydrometallurgy. [0003] In the process of zinc electrolysis, process parameters such as the acid / zinc ion concentration of the electrolyte and the current...
