In 2020, the European Union officially designated strontium as a Critical Raw Material (CRM) due to its diverse applications and limited global producers, with Spain as one of the primary producers and the only one in the EU. This comprehensive review discusses strontium market dynamics, global reserves, and technological advancements in mineral processing techniques to extract and concentrate its main bearing minerals, celestine (SrSO4) and strontianite (SrCO3). The review highlights the shift in strontium demand, led until the mid-2000s by applications in cathode-ray tube (CRT) glass, to current uses focused on pyrotechnics, ceramic magnets and drilling fluids.

锶矿物作为关键原材料 — 市场动态、加工技术和未来挑战


2020 年，由于其应用多样化且全球生产商有限，欧盟正式将锶指定为关键原材料 （CRM），西班牙是主要生产国之一，也是欧盟唯一的生产国。本综述讨论了锶市场动态、全球储量和矿物加工技术的技术进步，以提取和浓缩其主要含矿物天青矿 （SrSO4） 和钨矿 （SrCO3）。该评论强调了锶需求的转变，直到 2000 年代中期，阴极射线管 （CRT） 玻璃的应用才导致锶需求转变为目前的用途，主要集中在烟火、陶瓷磁铁和钻井液上。
