Rare earth elements (REEs) are widely used in high-tech fields such as permanent magnetic materials, catalysts, fluorescent materials and high-performance batteries due to their unique physical and chemical properties. However, the mining and separation process of rare earth resources is complicated and costly. Traditional rare earth extraction methods include solvent extraction and liquid membrane separation, but these methods have problems such as low efficiency, poor selectivity and environmental pollution. Compared with traditional solvent extraction, Kingshan ion exchange resin has the following advantages: high selectivity, simple operation, environmental friendliness and strong renewability.

Application scenario:

Treatment of rare earth ore leachate

In the mining process of rare earth ore, acidic solutions (such as hydrochloric acid, sulfuric acid, etc.) are usually used to leach the ore to obtain a leachate containing a variety of rare earth elements. Ion exchange resins can be used to efficiently adsorb the target rare earth elements from these leachates to achieve initial enrichment.

Recycling of used electronic products

Waste electronic products contain a large amount of rare earth elements, such as neodymium and dysprosium in neodymium iron boron magnets. After disassembly and crushing, the rare earth elements are leached out with acidic solution and then recycled with ion exchange resin.

And industrial wastewater treatment, comprehensive utilization of rare earth tailings and other applications.

Jiangsu Kingshan New Materials provides a series of resins for recovering rare earth metals in acidic leaching solutions, which have the characteristics of good selectivity, high adsorption rate and convenient regeneration.
