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。
The chemical composition, mineral composition, ore size and ore structure of ore are analyzed by a variety of testing methods to study the process mineralogy of a polymetallic deposit in a certain place in Shaanxi Province. The results show that the polymetallic ores are dominated by magnetite and ilmenite. In addition, the polymetallic ores contain a small amount of pyrite and limonite. Vanadium is mainly found in magnetite. Titanium is mostly found in ilmenite in. Ore composition is simple, is conducive to the full dissociation of minerals. Magnetite and ilmenite are mostly sparsely disseminated - star-like distribution in gangue mineral grains, a small amount of gangue minerals, and pyrite and hematite with less.
