我国内生磷矿特点一般为中低品位磁铁矿与低品位磷矿和其
他可利用组分共生.通过合理的综合回收选矿工艺路线,采用常温浮
选回收低品位磷矿.变质磷矿采用浮选回收实现了工业化.
The endogenetic phosphate ores in China,
characterized with cooccurrence of low grade
magnetite and other recoverable compositions, can be
comprehensively utilized using flotation techniques at
ambient temperature. The metamorphic phosphate ores
have been commercially beneficiated for decades.
