Process Mineralogy of Vanadium Titano-magnetite from Shanxi

摘要: 利用多种检测手段对矿石化学成分、矿物组成、矿石粒度和矿石结构等进行分析,研究陕西某地多金属矿的工艺矿物学。研究表明:该多金属矿以磁铁矿和钛铁矿为主,此外含有少量的黄铁矿和赤褐铁矿等,钒多赋存于磁铁矿中,钛多赋存于钛铁矿中。矿石组构简单,有利于矿物的充分解离。磁铁矿和钛铁矿多以稀疏浸染状-星点状分布于脉石矿物粒间,少量包裹于脉石矿物中,且与黄铁矿和赤铁矿连生较少。Abstract: The chemical composition,mineral composition,ore particle size and ore structure were deeply analyzed using a variety of detection methods to investigate the process mineralogy of a polymetallic mineral from Shanxi.It is shown that the polymetallic mineral mainly contains magnetite and ilmenite,as well as a small amount of pyrite and limonite.Vanadium and titanium mainly exist in magnetite and ilmenite,respectively.The simple ore fabric is beneficial for full dissociation of the mineral.The magnetite and ilmenite mainly exist in gaps of the gangue mineral grains in form of sparse impregnated-star status,and small amount of magnetite and ilmenite are wrapped in the gangue minerals,with few adhesions to pyrite and hematite.
