摘要
塔吉克斯坦某含银铜锡重选粗精矿中的铜、锡难以分离,为了查清铜锡重选粗精矿的成分及分布状态等特征,为选矿工艺的选择提供依据,采用矿物自动分析系统(AMICS)对试样的矿物组成、主要矿物粒度、矿物共生情况、矿物单体解离情况等特征进行研究。结果表明,重选粗精矿中主要有用矿物为孔雀石、羟锡铜石、锡石、黄锡矿等,重选粗精矿中有用矿物粒度大小不一,且连生体较多,共生嵌布关系极为复杂。伴生有用矿物成分为辉银矿、自然银、重晶石、白钨矿等,可考虑进行综合回收利用。基于重选粗精矿的AMICS分析结果,可采用重选—浮选相结合的联合工艺流程分选。
The copper and tin in a silver-bearing copper-tin rougher concentrate from Tajikistan are difficult to separate.To clarify the composition and distribution characteristics of the copper-tin rougher con⁃centrate,providing a basis for the selection of mineral processing technology,an automatic mineral analysis system(AMICS)is used to study the mineral composition,main mineral particle size,symbiotic situation of minerals,and the liberation condition of mineral monomers in the silver-bearing copper-tin ore rougher concentrate.The analysis of the separation effect is also conducted.The results show that the main valuable minerals in the rougher concentrate are malachite,stannite,cassiterite,and mushistonite.The particle sizes of the valuable minerals in the rougher concentrate are uneven,and there are many intergrowths with an ex⁃tremely complex symbiotic intergrowth relationship.The accompanying valuable mineral components in⁃clude acanthite,native-silver,barite,scheelite,which can be considered for comprehensive recycling and utilization.Based on the AMICS analysis results of the rougher concentrate,a combined process of gravity separation and flotation can be adopted.
