Extractors (extractor boxes, extractors, and mixing clarification units) are a stepwise contact extraction equipment, consisting of a stirring system, mixing zone, clarification zone, and phase separation zone. In each stage, the two immiscible liquid phases will undergo mixing, clarification, and phase separation processes, thereby achieving mass transfer and separation of the target solute between different liquid phases.
Work Process
The specific operation process of the extraction tank (mixed clarification tank) involves the料液and extracting agent being pumped into the mixing chamber through their respective feed ports by a feed pump. A high-speed stirrer then facilitates the mixing and mass transfer between the料液and extracting agent. Subsequently, the mixture passes through overflow baffles into the clarification chamber, where separation of the light and heavy phases occurs under the force of gravity. The separated light and heavy phases then enter different outlets, completing one extraction cycle. In actual production, the extraction tank is typically a multi-stage series configuration, including extraction, back-extraction, washing, and regeneration sections, among others, which should be configured according to the specific production process.

Mixed mass transfer process
Raw Material IntroductionThe feedstock liquid and extractant are introduced into the mixing chamber of the extraction tank through their respective feed ports. For instance, in hydrometallurgy, a water solution containing metal ions serves as the feedstock liquid, while an organic extractant is introduced as another liquid phase into the mixing chamber.
Agitate and mixThe mixing chamber is equipped with a stirrer that rotates at high speed, allowing the raw material liquid and the extracting agent to come into full contact and mix. Under the action of stirring, the solute is transferred from the raw material liquid to the extracting agent, forming a two-phase solution. The intensity and duration of stirring have a significant impact on the mass transfer efficiency. Inadequate stirring can result in insufficient contact between the two phases, reducing the mass transfer efficiency; excessive stirring may lead to emulsification, increasing the difficulty of subsequent separation.
Separation process
Overflow enters clarification chamberThe mixed liquid enters the clarification chamber through overflow baffles. The clarification chamber is a spacious room with a large volume, providing ample space for the static stratification of the liquid.
Gravity Natural SeparationIn the clarification chamber, due to the different densities of the raw liquid and the extracting agent, under the action of gravity, the two phases gradually separate. The denser phase (usually the heavy phase) sinks to the bottom, while the less dense phase (usually the light phase) floats to the top, forming a clear phase interface.
Partial contact reduces mass transfer efficiency; excessive stirring can lead to emulsification, increasing the difficulty of subsequent separation.
Key Features
● High-grade efficiency
●Simple Structure: The extraction tank typically consists of a tank body, interface adjusting pipe, motor reducer, agitation shaft, impeller, speed controller, and a movable platform, etc., with a relatively simple structure.
●Stable Operation and Strong Adaptability: Due to the larger volume of the extraction tank and the higher liquid storage capacity, it can accommodate a certain range of fluctuations in the feedstock liquid. After balancing, the operation is relatively stable and highly adaptable.
● Scalability with Reliability: Design parameters such as extraction efficiency remain relatively reliable after scaling up.
