    Characterization Study of an Abundant Secondary Resource for Yttrium and Heavy Rare Earths

    Under the Critical Materials Institute (CMI), an Energy Innovation Hub funded by the US Department of Energy, the Florida Industrial and Phosphate Research Institute in collaboration with Oak Ridge National Laboratory and Colorado School of Mines are conducting research to recover rare earths, phosphorus, magnesium and uranium from phosphate clay. Phosphate mining in Florida generates more than one ton of phosphate clay, or slime, per ton of phosphate rock produced. Since the start of large-scale washing and desliming for phosphate beneficiation, more than 2 billion tons of slime have accumulated. This tremendous amount of phosphate clay represents secondary resources of approximately 600 Mt of phosphate rock, 600 kt of rare earth elements (REEs) and 80 million kilograms of uranium. In addition, REEs in Florida phosphate clay contain a higher proportion of yttrium and heavy rare earths than many of the primary rare earths minerals in the world. This paper presents the most comprehensive chemical, physical and mineralogical characterization of phosphate clay. Many advanced analytical tools were utilized for this study, including QEMSCAN, Mineral Liberation Analyzer, Laser Diffraction Particle Analyzer, and ICP-MS. The information generated from this study is vital for formulating mineral separation schemes to concentrate REE- and P-containing materials for downstream extraction of these critical elements.

    About the Speaker

    Dr. Patrick Zhang | Florida Industrial and Phosphate Research Institute | Bartow, FL, United States

    Dr. Patrick Zhang obtained his Ph.D. from University of Nevada, Reno, M.S. from the Chinese Academy of Sciences and B.S from Northeastern University, China, all in metallurgical engineering. He has 25 years of experience in phosphate research and six years of research background in gold extraction and cyanide waste treatment. Since 1993, he has served as a Research Director with the Florida Industrial and Phosphate Research Institute (FIPR), Florida Polytechnic University. In this post, he led the Institute's beneficiation program to global prominence by conducting nearly 30 in-house projects, managing over 100 research contracts, chairing eight international conferences, editing seven books on phosphate processing, authoring numerous technical papers and book chapters, and delivering keynote/plenary speeches at various conferences.
