[en] The method of continuous purification of liquid metal in a circulation circunit is described. The method includes the removal of liquid metal from the volume hydraulically bound with the circuit up to the level at which gaseous impurities are separated from the melt, stabilization of melt level in the volume and removal of gaseous impurities. The specific feature of the method lies in the fact that with the aim of improving the purification qualityy the removal of melt and stabilization of the level is realized by excitation in the volume hydroaulically bound with the circuit, electromagnetic osxillations with parameters ensuring the melt pressure, at least equal to the circuit pressure. The suggested method ensures wffctive melt purification in case of long-term circuit operation and the possibility of instal lation of the purification system in any point of the circulation circuit
