[0021] In this embodiment, a high-temperature slag suction pump is used to transport the high-temperature melt generated during the production of sponge titanium to a melt processing device. The melt processing device processes the high-temperature melt to obtain the corresponding molten salt electrolyte and slag sample. The molten salt electrolyte is then transferred to the raw material processing system for use, and the slag sample is transferred to the slag yard. This process effectively treats the high-temperature melt generated during the production of sponge titanium, increases the corresponding revenue, and avoids the waste of the high-temperature melt.
