青海榴辉岩型金红石矿工艺矿物学研究

Eclogite Type Qinghai Rutile Technological Mineralogical Research

通过光学显微镜、多元素分析分析法、电子探针、X射线粉体衍射仪等手段,对青海榴辉岩型金红石矿的矿物学开展了详细的研究,查明了该矿主要由Fe、Al、Mg、K、Na、Mn、Si、S、O等元素组成;查明了该矿中的矿物主要是由铁铝榴石、绿辉石、角闪石、绿泥石和金红石等矿物组成,其中石榴子石含量为56.5%,绿辉石含量为24.2%;查明了矿石的结构构造,并进行了主要矿物工艺矿物粒度测定。研究结果表明,矿石中钛主要以金红石的形式存在,嵌布粒度为中细粒嵌布,被石榴子石和绿辉石包裹,造成金红石选矿回收率较低,但石榴子石和绿辉石颗粒较粗,且大部分金红石与石榴子石和绿辉石之间的接触较为平直,有利于金红石的单体解离,选矿回收难度不大。该工艺矿物学研究为青海榴辉岩型金红石矿的选冶工艺及其综合利用提供了重要的参考依据。

The mineralogy of the eclogite-type rutile in Qinghai was studied by means of optical microscope, multi- element analysis, electron probe and X-ray powder diffractometer. It was found that the ore is mainly composed of Fe, Al Mg, K, Na, Mn, Si, S, O and so on. It is found that the minerals in the ore are mainly composed of iron-alumi- num garnet, omphacite, amphibole, chlorite and rntile, The content of garnet is 56. 5% and the content of pyroxene is 24.2%. The structure and structure of the ore are identified, and the mineral size of the main mineral is deter- mined. The results show that the titanium in the ore is mainly in the form of rutile, the embedding size is medium and fine grain embedding, and the rutile and the pyroxene are wrapped by the garnet and omphacite, resulting in lower recovery rate of rutile. Thick, and most of the futile and garnet and pyroxene contact between the more straight, is conducive to the dissolution of rutile monomer, mineral processing recovery is not difficult. This process mineralogy provides important reference for the selection and smelting process and comprehensive utilization of eclo- gite type rntile in Qinghai.
