Integrated Extractor Tank (extractor box, extractor, and mixing clarifier) is a stepwise contact extraction equipment, consisting of a mixing system, mixing zone, clarification zone, and phase separation zone. In each stage, the two immiscible liquid phases 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 working process of the extraction tank (mixed clarification tank) involves the feedstock and extractant entering the mixing chamber through their respective feed openings, driven by a feed pump. A high-speed stirrer then mixes the feedstock and extractant for mass transfer. Subsequently, they flow through overflow baffles into the clarification chamber, where separation of the light and heavy phases occurs under gravity. The separated phases then enter different outlets, completing one extraction cycle. In actual production, the extraction tank is typically a multi-stage series configuration, including stages such as extraction, back-extraction, washing, and regeneration, which are configured according to the specific production process.

Mixed mass transfer process
Raw Material IntroductionThe raw material liquid and the extractant are separately 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 raw material liquid, while an organic extractant is introduced as another liquid phase into the mixing chamber.
Agitate and mixThe mixing chamber is equipped with a blender that rotates at high speed, allowing the raw material liquid and solvent to come into full contact and mix. Under the action of the blender, the solute is transferred from the raw material liquid to the solvent, forming a two-phase solution. The intensity and duration of blending have a significant impact on the mass transfer efficiency; insufficient blending may lead to inadequate contact between the two phases, reducing the mass transfer efficiency; excessive blending, on the other hand, may cause emulsification, increasing the difficulty of subsequent separation.
Separation Process
Overflow enters the clarification chamberThe mixed liquid enters the clarification chamber through overflow baffles. The clarification chamber is a spacious room with a large cavity volume, providing ample space for the liquid to settle and separate.
Gravity Natural SeparationIn the clarification chamber, due to the different densities of the raw liquid and the extracting agent, under the influence 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 on 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 adjustment pipe, motor reducer, stirrer shaft, impeller, speed controller, and a movable platform, etc., with a relatively simple structure.
●Stable Operation, High Adaptability: Due to the larger volume of the extraction tank and higher liquid storage capacity, it can accommodate a certain range of fluctuations in the material liquid. After adjustment and balance, the operation is relatively stable and highly adaptable.
● Scalable Reliability: Single-stage extraction rates and other design parameters remain relatively reliable after scaling up.
