According to the natural characteristics of different salt lake lithium concentration and magnesia-lithium ratio, the process of extracting lithium from salt lake shows the characteristics of "one lake and one policy". Solvent extraction is widely used in the process of extracting lithium from brine with high magnesia-lithium ratio in Qinghai Salt Lake.

Centrifugal solvent extraction is an efficient separation method, which has been widely used in petrochemical industry, hydrometallurgy, modern medicine, biological fermentation, nuclear fuel extraction and other industries. In the field of lithium extraction from salt lake, centrifugal solvent extraction has shown the technical characteristics of high efficiency, short process and low cost. The engineering application of Genel Salt Lake fully proves this advantage.

The general process of extracting lithium by centrifugal solvent extraction includes the steps of feed liquid pretreatment, extractive agent preparation, extraction, washing, back extraction, saponification, iron removal, oil-water separation, evaporation crystallization, drying and packaging. Among them, the centrifugal extraction equipment needs to solve the problem of corrosion resistance and solvent stability of the material.

Shandong Liancui Equipment Technology Co., LTD. Perfluorinated material integral molding centrifugal extractor, not only to ensure the optimization of technical parameters, but also to ensure that the equipment materials are resistant to hydrochloric acid and tributyl phosphate (TBP) and other corrosive substances. The equipment adopts fluorine material rotor, which is not only light in weight, but also greatly reduces the operating power and operating cost of the equipment. Compared with traditional corrosion-resistant metal materials, the purchase cost of the equipment is also greatly reduced, which provides strong support for the upgrade and iteration of the traditional extraction tank equipment for lithium extraction from salt lake.

In order to better meet the needs of the new high-efficiency extraction lithium extractant system, Shandong Lianceng Equipment Technology Co., Ltd. has continued to carry out research and development work in weakening the emulsification of extractant, strengthening mass transfer, efficient phase separation, and intelligent control of multi-level systems, and has achieved good results. These innovations have found engineering applications in the fields of ore lithium extraction, decommissioned power battery recycling and rare and precious metal extraction, contributing positively to improving efficiency and achieving sustainable development.
