    钪的资源及回收提取技术发展现状

    Scandium resources and status of scandium extraction and recycling technology

    • 摘要: 钪属于稀土元素,钪及其化合物性质优异,在照明、合金、陶瓷材料等许多行业应用广泛。我国钪资源十分丰富,储量居世界第一位。但是钪多与其他矿物伴生,少见独立矿物,提取困难,价格昂贵,我国在钪的提取和深加工方面的研究仍较为薄弱,与俄罗斯差距较大。文章总结了钪的资源概况及其用途,根据含钪物料性质的不同分三种类型综述了不同含钪物料中钪的提取方法和实例。根据提钪工艺的现状和进展提出选冶联合是今后提钪工艺发展的方向;湿法冶金工艺要寻找高效助浸剂,提高浸出效率,降低药剂消耗;要寻找更多的钪资源和提钪方法;在提钪的同时综合回收其他有价元素;延长产业链,努力发展钪的深加工,提高产品附加值。

       

      Abstract: Scandium belongs to the rare earth element, properties of scandium and its compounds is excellent and be widely used in lighting, alloys, ceramics and many other industries. Our resources are very rich in scandium, reserves ranking first in the world. However, much scandium associated with other minerals, rare independent mineral, extraction difficult and expensive, study on the extraction of scandium and deep processing is still relatively weak, have a big gap with Russia. This paper summarizes the scandium resource profile and its use, review scandium extraction methods and examples of different scandium-containing material depend on the three types of different properties scandium-containing material. According mention scandium process status and progress made dressing and smelting joint is the future direction of scandium recycling technology development; hydrometallurgical process to find efficient aid infusion, improve the leaching efficiency and reduce drug consumption; to find more resources and more scandium recycling methods; recovery of other valuable elements integrated; extend the industrial chain, and strive to develop the deep processing of scandium, increase value-added of products.
