摘要
某微细粒嵌布银矿含银179 g/t,通过工艺矿物学研究,查明了银元素在该类矿石中的分布及其赋存状态、含银矿物的粒度分布、嵌布特性。研究表明,该银矿中的银绝大部分以独立矿物形式存在。银的独立矿物有自然银、辉银矿、硫铁银矿三种,分别占总银的76.60%、12.10%、1.00%,共计89.70%。从工艺矿物学方面论证该银矿的矿石利用问题,并对提高选矿理论指标进行探讨。
A micro-grained dissemination silver ore contains 179 g/t Ag. Through process mineralogy study, with studying on the mineralogical characteristic, the mineral composition, silver occurrence state, minerals structure and texture, and the dissemination characteristics of its main minerals were determined. The experiment showed that this silver ore exists in form of monominerals. There are three forms of monominerals-natural silver, argentite and sternbergite. 89.70% of the total silver comprised of natural silver, being 76.60%, argentite, being 12.10% and sternbergite, being 1.00%; and make use of the silver ore and discuss to theory of the target of mineral dressing.
