稀土金属是一种重要但稀缺的资源，在发达国家及其技术先进的经济体中发挥着特别重要的作用。由于中国的供应垄断，稀土元素在国际矿产商品市场上的混乱迫使工业化国家启动密集的计划，以发现这些元素的新来源（甚至考虑后处理尾矿）。本文对邦加岛水滑石尾矿的矿物组成进行了研究。分析的尾矿样品含有高达21.23%w的独居石，高达17.55%w的磷钇矿（Sungkap，Bangka），以及锆石、钛铁矿、金红石、假金红石和绿柱石。锡渣中除稀土元素外，还鉴定出钽和铼。作者估计，每年至少有10，000吨含稀土的矿物（轻稀土独居石和重稀土磷钇矿）可以进一步加工。
REE metals are a vital yet scarce resource which play a particularly significant role in developed countries and their technologically advanced economies. Disturbances in the international mineral commodities market for REE’s caused by the Chinese supply monopoly force industrialized countries to launch intensive programs to discover new sources of these elements (even considering post-processing tailings). This paper discusses the mineral composition of tailings obtained in cassiterite extraction on Bangka Island. The analyzed tailing samples contain up to 21.23%wmonazite, up to 17.55%w xenotime (Sungkap, Bangka), as well as zircon, ilmenite, anatase, rutile, pseurorutile, and cassiterite. Aside fromREE’s, niobiumand tantalumwere identified in slag formed during tin smelting. The authors estimate that annually a minimum of 10,000 tons of minerals containing REE’s (both LREE’s-monazite and HREE’s-xenotime) can be further processed.
