Abstract: The continuous electrolysis technology with blocklike multianodes in the production of rare earth metals is introduced in this paper.By adopting this technology, continuous electrolysis processes can be realized, cell voltage fluctuation range is reduced 70%, the percent of pass of products are increased, the power consumption is savedmore than 1 000kW ·h, the working in tension is lightened, the problem of adopting rod multi_anodes electrolysis is solved, and service life of the cell can be prolonged more than 3 months.
