摘要

2020 年，欧盟正式将锶指定为重要原材料 (CRM)，因为锶的应用多种多样，但全球生产商有限，西班牙是主要生产国之一，也是欧盟唯一的生产国。本综述讨论了锶的市场动态、全球储量以及用于提取和浓缩主要含锶矿物--天青石（SrSO4）和锶铁矿（SrCO3）的矿物加工技术的进步。该综述强调了锶需求的转变，即从 2000 年代中期以前的阴极射线管 (CRT) 玻璃应用，转变为目前的烟火、陶瓷磁铁和钻井液应用。

Strontium minerals as critical raw materials — Market dynamics, processing techniques, and future challenges

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.

期刊介绍： The purpose of the journal is to provide for the rapid publication of topical papers featuring the latest developments in the allied fields of mineral processing and extractive metallurgy. Its wide ranging coverage of research and practical (operating) topics includes physical separation methods, such as comminution, flotation concentration and dewatering, chemical methods such as bio-, hydro-, and electro-metallurgy, analytical techniques, process control, simulation and instrumentation, and mineralogical aspects of processing. Environmental issues, particularly those pertaining to sustainable development, will also be strongly covered.
