我国内生和变质磷矿分布特点及选矿技术

Distribution characteristics and beneficiation of endogenetic and metamorphic phosphate ores in China

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 co-occurrence 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.
