江西某铅锌矿石工艺矿物学研究

江西某铅锌矿在现采矿境界下部发现较大新矿体，为确定新探明资源的合理开发利用工艺，对新探明资源进行了工艺矿物学研究。结果表明：该矿石中矿物种类复杂，有用元素主要有铅、锌、银、金等，主要铅、锌、银矿物有方铅矿、闪锌矿、硫锑铅银矿、硫锑铜银矿。铅锌矿物嵌布特征复杂，共生关系密切，受构造应力作用破坏，闪锌矿碎裂成碎粒，被黄铁矿、方解石等胶结；银矿物在方铅矿中呈蠕虫状、微脉状分布。方铅矿、闪锌矿均为极不等粒嵌布，矿石属难解离、难分选铅锌矿石。最后指出了选矿试验研究过程中应重视的几个问题。

Research of Processing Mineralogy of a Lead-zinc Ore from Jiangxi

A new relative large ore body was found under the present mining realm in a lead-zinc mine in Jiangxi.The processing mineralogy of the ore was studied in order to explore a suitable method to develop the new resources.The results showed that there were variety of complex minerals in the ore.Pb，Zn，Ag，Au，i.e.were the main valuable elements，and Pb，Zn，Ag mainly exist in galena，sphalerite，brongniardite and polybasite.Lead-zinc minerals have complex dissemination and are closely associated with each other.Sphalerite is broken into pieces with the destruction of the tectonic stress action and is cemented with calcite and pyrite.The silver minerals present in galena，which intersect the sphalerite in wormlike or micro-vein form.Galena and sphalerite are dispersed as various sizes of grains in the ore，therefore it was very difficult to liberate and separate.Finally,several issues should pay attention to during mineral processing of the ore were put forward
