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 saved more than 1 000 kW·h/t, the working intension 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 .
