Recently, Wet Drum Magnetic Separator(LIMS), Vertical Ring Pulsating High Gradient Magnetic Separator(VPHGMS) and High Extraction Magnetic Filter(HEMF) independently developed by SLon have been successfully applied in a cesium separation plant in Zimbabwe, achieving the first breakthrough of magnetic separation technology in the field of rare metal cesium separation and setting a new benchmark for global cesium resource development.

For a long time, there are significant technical barriers in cesium ore separation due to the complex occurrence of minerals and the diversity of associated impurities. The traditional mineral processing technology in the industry mainly relies on flotation, but it has always faced the triple bottlenecks of low efficiency, high cost and high pollution. SLon applied magnetic separation technology to the entire process of cesium ore separation for the first time. By adopting a multi-stage iron removal process, precise separation is achieved, which not only significantly improves the quality of cesium concentrates, but also greatly reduces the amount of subsequent flotation reagents. The project adopts a three-stage magnetic separation plus flotation process. The raw ore is processed by LIMS, VPHGMS and HEMF. After a series of on-site commissioning, the iron content of the non-mags dropped to 0.1%-0.2% and the flotation index after magnetic separation is excellent.

The success of the Zimbabwe project is a strong proof of the innovative strength of SLon. In recent years, SLon has continued to deepen its research in the field of “magnetic separation + rare metals” and mastered a number of key technologies. This breakthrough not only promotes China’s magnetic separation technology to the international stage, but also creates a “Chinese solution” for the efficient development of rare metals, providing replicable experience for the development of low-grade cesium ores and other rare metal resources around the world. It has far-reaching significance for ensuring the strategic security of mineral resources and accelerating the technological upgrading of the industry, and also injects new momentum into the transformation of rare metal separation towards green and efficient.
