摘　　要：本文针对内蒙某锡多金属硫化矿中微细粒锡石回收进行了选矿试验研究。在工艺矿物学研究基础上,进行了脱泥、脱硫等预处理,优化了锡石浮选环境,开展了药锡石浮选含钙脉石矿物的抑制剂和锡石高效捕收剂筛选研究。最终采用“脱泥-浮硫-浮锡”的全工艺流程,在入选锡品位0.55%的情况下,可以获得浮锡精矿锡品位6.52%,回收率68.56%的技术指标,实现了微细粒锡石的有效富集,为微细粒锡石资源高效利用提供技术依据。In this paper,the test study on the recovery of fine tin particles from a tin polymetallic sulfide ore in Inner Mongolia was carried outBased on the study of technological mineralogy,the pretreatment of deslimation and desulphurization was carried out,and the flotation environment of cassiterite was optimized.Finally,the whole technological process of"desliming-floating sulfur-floating tin"is adopted.Under the condition of inclusion of 0.55%tin grade,the technical indexes of floating tin concentrate grade of 6.52%and recovery rate of 68.56%can be obtained,which realizes the effective enrichment of fine tin stone and provides a technical basis for the development of this resource.
