Extraction equipment in hydrometallurgy industry

Prosea extraction equipment which widely used in the hydrometallurgy industry and favored by a large number of customers. With the decline of ore grade and the increasingly strict requirements for environmental protection, the role of hydrometallurgy in non-ferrous metal production is becoming increasingly important. Hydrometallurgy mainly includes leaching, liquid-solid separation, solution purification, solvent extraction, and wastewater treatment.

As an important process in the separation and purification of non-ferrous metals copper, nickel, cobalt, uranium, rare metals tantalum, niobium, tungsten, molybdenum, vanadium, and rare earth metals indium lanthanide etc., solvent extraction plays a crucial role in the final prodcution efficiency and product quality. Besides, solvent extraction also can be used for lithium extraction from lithium precipitation mother liquor, or for purification and separation of Uranium and Plutonium in the Nuclear reprocessing.

Solvent extraction(liquid-liquid extraction) has the advantages of high extraction and separation efficiency, no filtration, less solvent consumption, high recovery rate, large production capacity, and easy automation and continuity. In recent years, it has been widely used in departments such as hydrometallurgy, petroleum, chemical engineering, and environmental protection.

Solution：Multistage Liquid–Liquid Countercurrent Continuous Extraction

Multistage Liquid–Liquid Process Description:
1. The Multistage Liquid–Liquid Extraction process is not limited to four-stage pickling, alkali washing and water washing, and the number of countercurrent washing stages can be increased according to the actual situation;
2. The Multistage Liquid–Liquid Extraction process is suitable for separating organic mixtures immiscible with water such as acetochlor, alachlor, etc.;
3. The Multistage Liquid–Liquid Extraction process relies on centrifugal separation (hundreds to thousands of times the gravity under the same conditions), and the separation efficiency is high;
4. The Multistage Liquid–Liquid Extraction process equipment occupies a small area, low power consumption, and less residual liquid, which can realize the continuous production of the acetochlor washing process section;

Relative equipment

Mixer Settler

Mixer settlers are a class of Mixing Separation equipment used in the solvent extraction process. A mixer settler reactor consists of a first stage that mixes the phases together followed by a quiescent settling stage that allows the phases to separate by gravity. Mixer Settler is made by overall injection molding, without bonding or weld seams which by Prosea Tech design and manufacture.
