Abstract:Through the industrial experiment of direct electrotellurium from tellurium electrodeposition by swirling electrodeposition technology, it is concluded that the current efficiency is 97.1% at an optimum current density of 150 A/m2, the output per unit area of the electrode plate is 5.04 kg/(m2·d), and the power consumption is 2699.5 kWh/(t·Te), the cast product meets the requirements of Te9999 in YS / T 222-2010. In the industrial application process, it is still necessary to increase the electro-hydraulic filtration facility.It is proved that the swirling electrodeposition technology can produce tellurium from electrodeposition economically and effectively, with high efficiency, large yield per unit area, simple operation and feasibility.
