摘要
峨眉大火成岩省内带攀西地区的攀枝花、红格、白马、太和等矿床的钒钛磁铁矿矿石量约100亿t,V2O5储量1580万t、TiO2储量8.7亿t,此外还蕴含着丰富的Co、Ga、Sc、Cr等十多种稀有金属.尽管自20世纪八九十年代V和Ti逐渐得到了利用,但是Co、Ga、Sc、Cr等元素尚未得到综合利用,这些矿床的尾矿中还有巨量的各种金属元素.本文对近年来获得的磁铁矿、钛铁矿、单斜辉石电子探针和激光等离子质谱原位分析数据进行了系统分析,发现Ga和Cr主要赋存在磁铁矿中,Co主要赋存在硫化物和磁铁矿中,Sc主要赋存在单斜辉石和钛铁矿中;而且不同岩体中的磁铁矿、钛铁矿和单斜辉石中各种元素的含量存在差异.这些分析为矿石、尾矿甚至某些岩石中这些元素的综合利用提供了重要信息.
Abstract
The Panzhihua,Hongge,Baima,and Taihe deposits in the Panxi area within the inner zone of the Eemsishan Large Ingenious Provence contain about 10 billion tons of V-Ti magnetite ores,in which there are 15.8 million tons of V2O5 and 0.87 billion tons of TiO2,as well as abundant rare metals including Co,Ga,Sc,Cr,and so on.Although V and Ti in the magnetite ores have been gradually utilized since 1980-1990's,other elements including Co,Ga,Sc,and Cr have not been comprehensively utilized yet.Tailings of these deposits,accumulated in the past decades,contain great amount of metals including V,Ti,Co,Ga,Sc,Cr,and so on.The recently obtained electron microprobe and LA-ICPMSin-situ analytical data of magnetites,ilmenites and clinopyroxenes from the layered intrusions in those deposits have been systematically analyzed in this paper.It is concluded that Ga and Cr are dominantly contained by magnetite,Co is mainly hosted in sulfides and magnetite,and Sc is mainly occurred in clinopyroxene and ilmenite.In addition,there are different contents of various elements in magnetites,ilmenites and clinopyroxenes from the different layered intrusions.These conclusions are very important for the integrated utilization of V,Ti,Co,Ga,Sc,Cr in the V-Ti magnetite ores,tailings and some kinds of rocks in the Panxi area.
