How is the residence time of the liquid in the extraction clarifier and mixing chamber controlled?

I would like to ask the experts. Also, I wonder if there are any experts with some knowledge of the design of clarification chambers and mixing chambers; I hope they can offer some guidance. Thank you!
This is mainly determined during the design phase. The design is based on experimental data from mixed clarification. Generally, the effective volume of the mixing chamber is designed based on the liquid residence time in it, while the area of the settling chamber is calculated based on the settling rate. The extraction mixing time for copper smelting is 2–3 minutes, and the settling rate in the settling chamber is 3.6–5.
It’s complicated; it’s the volume of the tank divided by the solution flow rate.
Simply put, the mixing time = volume of the mixing chamber / (flow rate of the organic phase + flow rate of the aqueous phase), and the settling time = volume of the settling chamber / (flow rate of the organic phase + flow rate of the aqueous phase)
