【摘要】 贵州织金低品位磷稀土矿:磷含量13.10%～21.39%;稀土含量0.070%～0.104%,储量巨大。为探索综合利用这部分含稀土磷矿资源的途径,对其矿石特征、物相组成、化学成份和分离富集工艺进行了系统地研究,并做了实验室制各稀土钙镁磷肥的实验,所得产品磷含量15.11%～17.58%、稀土含0.0837%～0.0971%。更多还原

【Abstract】 Enormous low-grade rare-earth-phosphor deposited in Guizhou-Zhijin which contain P (phosphorus) : 13.10%～21.39%; rare earth : 0.070%-0.104% respectively. Systematic study about the ores be made by us, for exploring their comprehensive utilization. Experiments about the preparation of the rare-earth calcium magnesium phosphate fertilizer also be made in our lab. The products obtained are with P 15.11%-17.58%, rare-earth 0.0837%-0.0971%.更多还原
