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,我们对其矿石特征、物相组成、化学成份和分离富集工艺作了系统地研究,并作了实验室制备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%。
Enormous reserves with low -grade phosphate rare -earth deposited in Guizhou -Zhijin, which conrain P （phosphorus） ： 13.10% - 21.39% ; rare earth：0.070% - 0. 104% respectively. For exploring their comprehensive utilization, systematic study about the ores＇ characteristic.phase composition.chemical composition.the separating and accumulating technology be made by us. And experiments about the preparation of rare - earth calcium magnesium phosphate fertilizer also be made in lab. The products obtained are with P 15.11% - 17.58%, rare - earth 0.0837% -0.0971%.
