Occurrence and screening- flotation separation for the beneficiation of rare earth elements and yttrium (REY) in core sediments from the Pacific Ocean

In this study, detailed grain size analysis, mineral identification and geochemical measurement aiming at deep-sea sediments collected from a station in the Pacific Ocean were employed to determine the occurrence of deep-sea REY-rich sediments. Based on that, the Screening-flotation separation was adopted to achieve efficient enrichment of REY in the sediments. The data set summarizes in detail the data of the above research content and the way of data sorting, including pictures and tables

本研究针对太平洋某站位采集的深海沉积物，开展了详细的粒度分析、矿物鉴定与地球化学测试，以明确富稀土元素及钇（Rare Earth Elements and Yttrium，REY）深海沉积物的赋存状态。在此基础上，采用筛分-浮选分离法实现了沉积物中REY的高效富集。本数据集详细汇总了上述研究内容的相关数据及数据整理方式，涵盖各类图表。
