湖南某复杂难选锡多金属矿工艺矿物学研究

针对湖南省某中高温热液裂隙充填交代型锡多金属矿进行了工艺矿物学研究。结果表明:该矿矿物组成复杂，种类较多。矿石中有用组分主要为锡和铋，其次为铜、萤石和银。锡、铋、铜分别以锡石、辉铋矿、黄铜矿赋存，银以类质同象赋存于多种硫化矿中。有用矿物主要有锡石、辉铋矿及少量自然铋、黄铜矿、萤石、少量辉铜矿等。除萤石以外，主要有用矿物以细粒嵌布为主，矿物嵌生关系紧密，属难选的矿石类型。最后提出了该锡多金属矿开发利用的建议。 

Study on the Technological Mineralogy of a Complex and Refractory Tin-polymetallic Ores in Hunan

According to the study on the technological mineralogy of a medium-high temperature fluid fissure filling metasomatic type tin-polymetallic ore from Hunan province, the mineral compositions of the ore are complex. The main valuable elements are tin and bismuth, followed by copper, fluorite and silver. The primary minerals for these elements are cassiterite, bismuthinite, chalcopyrite and isomorphism minerals in a variety of sulfide ore, respectively. Therefore, the valuable minerals are mainly cassiterite, bismuthinite and a small amount of natural bismuth, chalcopyrite, fluorite, and chalcocite, etc. Except for the fluorite, the useful minerals have fine dissemination sizes and closely symbiotic relationships, which makes the ore refractory. Based on this study, some suggestions for the utilization of this tin-polymetallic ore are put forward.
