黑龙江省正在开发的鸡西磷矿属低品位磷灰石矿,含磷量一般在P_2O_53％左右。该矿具有以下特点:①地质储量较大,矿体形态稳定,易选,以含P_2O_53.5％的大理岩型贫磷矿,经一次粗选、二次扫选和一次中矿再选的工艺流程,可以获得含P_2O_529.68％的磷精矿,回收率89.34％。以含P_2O_53.37％石墨硅酸盐型贫磷矿,经一次粗选、一次精选,可获含P_2O_528.48％的磷精矿,回收率77.96％。②矿石中伴生的有益元
Jixi phosphate mine under development in Heilongjiang Province is a low-grade apatite mine, with phosphorus content generally around P 2 O 53%. The mine has the following characteristics: ① large geological reserves, ore body morphology is stable, easy to choose, with P_2O_53.5% marble-type phosphate rock, after a roughing, secondary sweep and a mine re-election Process, you can get with P 2 O 5 29.68% of phosphate concentrate, the recovery rate of 89.34%. With P_2O_53.37% graphite silicate-type lean phosphate rock, after a rough selection, a selection, available P_2O_528.48% of phosphorus concentrate, the recovery rate of 77.96%.
