In the field of hydrometallurgy, the separation of manganese and magnesium has always been one of the technical challenges. Traditional methods suffer from low efficiency, high energy consumption, and limited product purity. Zhengzhou Tiei Extraction's CWL-M series centrifugal extractor, combined with solvent extraction technology, provides an innovative solution for the efficient separation of manganese and magnesium.

Technological Challenges and Breakthroughs in Manganese-Magnesium Separation
Manganese and magnesium have similar chemical properties and often coexist in solutions, making their separation difficult and inefficient using traditional precipitation methods. Solvent extraction methods, using selective extractants, can achieve high-precision separation of manganese and magnesium. The introduction of centrifugal extraction technology has further revolutionized this process in terms of efficiency and continuous operation.

Centrifugal Extraction Process Flow

1.Raw Material Pretreatment: The manganese- and magnesium-containing solution is prepared for extraction by adjusting its pH and concentration.
2.Extraction Stage: The solution is efficiently mixed with a specific organic extractant in a CWL-M centrifugal extractor.
The extractant selectively binds to manganese ions.
The centrifugal force field accelerates phase separation, forming a manganese-loaded organic phase and a magnesium-containing aqueous phase.
3.Washing and Purification: The loaded organic phase is washed to remove impurity ions, improving the purity of the manganese product.
4.Stripping stage: Adjust the conditions to transfer manganese from the organic phase to a new aqueous phase, obtaining a high-purity manganese solution.
The organic phase is regenerated and recycled.
5.Subsequent treatment: The manganese solution can be further electrolyzed to produce metallic manganese or used to prepare manganese salt products.
The magnesium-containing aqueous phase can be used to recover magnesium products or undergo harmless treatment.
