黄磷生产中的稀土元素分布

Rare Earth Distribution during Production of Yellow Phosphorus

通过研究稀土元素在黄磷生产中的分布 ,得出大部分稀土元素进入黄磷渣中 ,稀土元素在黄磷渣中的百分含量为 0 .0 2 7% ,大于其在原料磷矿石中的百分含量 0 .0 19% ,也大于其在地壳中的相对丰度 0 .0 15 3%。其原因是稀土元素极有可能以类质同像取代 Ca2 + 的形式进入渣中。由此提出从黄磷渣中回收稀土元素 ,这样既充分利用了资源 。

This paper studies the distribution of rare earth during production of yellow phosphorus A lot of rare earth entered into the sediment of yellow phosphorus In it REE contents (0 027%) was higher than that of raw material of apatite(0 019%) and that of the relative abundance in the earth crust(0 0153%) It was possible that Ca 2+ entered the sediment in the style of isomorphism So it was brought out recalling REE from the sediment of yellow phosphorus Not only it can apply resource, but also can protect the environment
