宜昌地区及周边类似的沉积型磷矿资源的赋存特点是条带结
构,是在较大颗粒下采用重介质分选磷质条带和脉石的有利条件.根
据矿石性质和产品用途,反浮选硅、镁等杂质合理可行.
The sedimentary phosphorites around Yichang
area are characterized with a ribbonlike ore texture
which favors the dense media preconcentration process
under a condition of very coarse particle size. Based
on the analysis of ore properties and the usage of
phosphate concentrate, a reverseflotation of silicate
and/or carbonate gangues is considered to be the most
suitable further beneficiation process for this kind of
ore.
