The rare earth ores (such as bastnaesite, monazite, ion adsorption type rare earth ores and the like) are co-associated ores of several to more than ten rare earth elements, and the high-purity, high-quality and low-cost separation of the mixed rare earth elements is important for the comprehensive and efficient utilization of rare earth resources.
Since the 70 th century of the 20 th century, the cascade extraction theory established by Xu Guangxian institutions and the like leads the rare earth separation theory and technology of China to the world, and under the guidance of the theory, the computer simulation technology, the linkage extraction separation technology and the like are further developed, so that the innovation of rare earth separation technology and industry of China is continuously led. At present, a solvent extraction separation method based on hydrometallurgical equipment such as a mixer-settler and the like has become a mainstream technology in the field of rare earth separation.

In the research process of an intelligent control system, most patents and articles focus on theoretical research of the extraction balance problem, and less attention is paid to the volume balance and flow balance problems which are continuously changed along with time and exist in the actual operation process of a mixer-settler.

The volume balance and flow balance control of the tank body can directly influence the quality of rare earth products output by the extraction separation production line. The simulation system for constructing the mixer-settler in the rare earth extraction and separation process is a key link for constructing an intelligent control system for rare earth extraction and separation.

The calculation result of the simulation system shows that:
(1) As shown in fig. 9, from the time t=0, the influence of the flow change of the organic phase is gradually conducted from the 1 st stage to the 50 th stage over time.
(2) As shown in fig. 10, from time t=0, the mixing chamber sump changes (compared to changes) due to the change in the organic phase flow, i.e., the mixing chamber "sump filling" process common in engineering practice.
(3) As shown in fig. 11, the mixing chamber "slot filling" process "squeezes" more aqueous phase due to the change in the organic phase flow, causing the aqueous phase flow to rapidly increase in a short time, and the aqueous phase flow peaks.
(4) As shown in fig. 9 and 11, the flow rates of the organic phase and the aqueous phase in the entire mixer-settler show a pattern of variation of repeated "oscillations" and the oscillation amplitude gradually decays, eventually approaching a new equilibrium state.
Through verification, the calculation result of the simulation system has good consistency with engineering practice data.
