Jun 15, 2019 The preparation of high-purity and ultra-pure rare earth metals is the basis of the research on high-performance rare earth materials. For the separation and purification of rare earth, iron is an impurity element with high content in rare earth products . In this paper, Pr(III) was selected as the representative of light rare earth elements.
The principal economic sources of rare earths are the minerals bastnasite, monazite, and loparite and the lateritic ion-adsorption clays. The rare earths are a relatively abundant group of 17 elements composed of scandium, yttrium, and the lanthanides. The elements range in crustal abundance from cerium, the 25th most abundant element of the 78 common elements in the Earths

fill materials materials the particles cannot move past each other to achieve density. Too much moisture leaves water-filled voids and subsequently weakens the load-bearing ability. The highest density for most soils is at a certain water content for a given compaction effort. The drier the soil, the more resistant it is to compaction. In a
