Abstract Metal indium (In) and its alloys have been widely used in semiconductor industries. In a Canadian sulfide ore, metal In mainly occurs as substitutes in stannite and sphalerite, and a sulfide mineral (i.e., roquesite), which accounts for 65% and 20% of the total In, respectively. In this work, the flotation method was adopted to pre-enrich the In in the Canadian sulfide ore due to its low cost, simple operation and high separation efficiency for fine particles. The findings of this research can provide a basis for the pre-treatments of In-bearing sulfide ores.

通过浮选技术从加拿大硫化矿中预富集铟

摘要 金属铟（In）及其合金已广泛应用于半导体行业。在加拿大某硫化矿中，金属In主要作为锡矿和闪锌矿的替代物以及硫化物矿物（即菱镁矿）出现，分别占In总量的65%和20%。本工作采用浮选法对加拿大硫化矿中的In进行预富集，具有成本低、操作简单、细粒分离效率高等优点。该研究结果可为含In硫化矿的预处理提供依据。
