摘要
为给湖北某铁矿石分选工艺流程提供参考,进行了矿石化学多元素、矿物组成、主要矿物嵌布特征、元素赋存状态等工艺矿物学研究.结果表明:矿石TFe含量为22.46%,元素Fe主要赋存在磁铁矿中,分布率为82.27%;矿石中磁铁矿常呈半自形粒状与脉石矿物共生嵌布,磁铁矿嵌布粒度不均,在+0.07 mm粒级分布率为50.51%,在-0.01 mm粒级分布率为6.36%,微细粒磁铁矿难以解离,会以连生体形式进入精矿;主要脉石矿物石膏常呈板状产出,与粒状磁铁矿及其他脉石矿物共生嵌布.
Abstract
In order to provide a reference for the determination of the separation process of an iron ore in Hubei Province,the process mineralogy of chemical multi-elements,mineral composition,main mineral embedding characteristics and element occurrence state were studied.The results show that the TFe content of the ore is 22.46%,and the element Fe is mainly present in magnetite,with a distribution rate of 82.27%.The magnetite in the ore is often semi-automorphic granular and intergrown with gangue minerals.The parti-cle size of magnetite is uneven.The distribution rate of+0.07 mm particle size is 50.51%,and the distribu-tion rate of-0.01 mm particle size is 6.36%.The fine-grained magnetite is difficult to dissociate and will en-ter the concentrate in the form of intergrowth.The main gangue mineral gypsum is often produced in a plate shape,and is symbiotically embedded with granular magnetite and other gangue minerals.
