摘　　要：深海富稀土底泥是一种具有潜在经济价值的稀土资源,然而,该类型资源的稀土赋存状态仍不十分明确。本文对西太平洋某地深海底泥开展了系统的矿物学研究,研究表明,稀土在深海底泥中主要的赋存矿物为磷酸盐矿物,包括磷灰石、独居石和磷钇矿等。但海底沉积物组成矿物粒度细小,加之磷酸盐类矿物本身粒度细小,导致其选矿分选的难度较大。因此,建议采用合理的方式将深海底泥中的组成矿物形成团聚,在原组成物的基础上长大呈粒,这也许是未来海底矿产资源利用的一个方向。Deep sea mud is a new type of rare earth elements resources with potential economical significance.However,the occurrence of Rare Earth Elements is contradictory.Through systematic study on mineralogy of the deep-sea mud from the Western Pacific Ocean,we determine that the main REE mineral is phosphate mineral,including apatite,monazite and xenotime.But the grain size of the deep-sea mud and the phosphate mineral are fine,and this result in the difficulty of ore concentration.Therefore,we suggest that utilizing some proper methods to form the agglomeration of the deep-sea mud,and this method is potential direction for future Utilization of submarine mineral resources.
