摘要
铬元素的化学性质、磷块岩的矿物组成及磷块岩破磨后不同粒级元素、矿物的分布特征与铬元素的相关性分析结果表明,昆阳磷矿磷块岩中铬元素赋存在陆源碎屑矿物白云母及白云母风化形成的伊利石、高岭石矿物中。
The chemical properties of Cr,the mineral composition of phosphate rock and the correlation between the distribution characteristics of elements and minerals of different grain grades and the Cr after the breakage of phosphate rock indicate that the Cr in the phosphate rock of Kunyang Phosphate Deposit occurs in the terrigenous clastic mineral muscovite and the illite and kaolinite minerals formed by the weathered muscovite.
