摘要
Tin,as one of the most important critical metals,has at-tracted great attention worldwide(Jiang et al.,2023,2020).China has the largest amount of tin resources in the world,ac-counting for nearly one-fourth of the world’s total(Jiang et al.,2020;Chen and Sheng,2015).Tin deposits in China mainly occur in the Nanling Range in southern China,the Sanjiang Basin in southwestern China,and the Great Xing’an Range in northeastern China,which account for 98%of the country’s tin resources,whereas tin deposits are relatively rare in north-western China(Ni et al.,2023;Chen et al.,2014,1992).
