摘要
青海省格尔木市那陵郭勒河西地区铁多金属矿规模大，具有铁铜金等多金属矿化，属于接触交代型铁多金属矿床。本文采用工艺矿物学研究方法，查明了矿石工艺矿物学特性。研究结果表明，矿石的组成矿物种类较为简单，金属硫化物主要是黄铜矿、磁黄铁矿、黄铁矿、闪锌矿；铁矿物主要是磁铁矿、赤铁矿。脉石矿物主要是石英、方解石、透闪石、透辉石；其次为石榴子石、白云母、蛇纹石。矿石中铁、铜锌矿物均具均匀细粒—微细粒嵌布特征；通过选矿可获得铜精矿、锌精矿、铁精矿。
Abstract
Iron polymetallic deposits in west Nalinggele river area of Golmud in Qinghai are mainly large-sized meta-somatism type deposits with characteristics of Fe-Cu-Au mineralization.This paper applied process mineralogical research methods to verify the process mineralogical characteristics of the ores.The research results suggested that the mineral composition of the ores was simple:metal sulfides were chalcopyrite,pyrrhotite pyrite,and sphalerite;iron minerals mainly included magnetite and hematite;gangue minerals occurred mainly as quartz,calcite,tremolite and diopside with lesser garnet,white mica and serpentine.Iron,copper and zinc minerals in the ores are character-ized by fine grained/ micro-fine grained dissemination characteristics;copper concentrate,zinc concentrate and iron concentrate are able to be acquired through beneficiation.
