Basic Research on the Separation of Scandium Yttrium, and the Rare Earths by Solvent Extraction
Author: Thomas R. Sweet
Publisher:
ISBN:
Category : Scandium
Languages : en
Pages : 125
Book Description
The solvent extraction behavior of scandium, yttrium, and a number of rare earth metals was investigated. Pure 2,2,6 tetramethyl 3,5 heptanedione, hereafter referred to as H(thd), was used as the chelating agent and the organic solvent. In addition, the closely related reagent, 1,1,1-trifluoro-5 5-dimethyl 2,4-hexanedione, hereafter referred to as K(fdhd), was studied as a reagent for separating europium and terbium by countercurrent distribution extractions. Atomic absorption as a method of analysis for the rare earths was also investigated. (Author).

Extractive Metallurgy of Niobium
Author: A.K. Suri
Publisher: Routledge
ISBN: 1351448978
Category : Science
Languages : en
Pages : 272
Book Description
The growth and development witnessed today in modern science, engineering, and technology owes a heavy debt to the rare, refractory, and reactive metals group, of which niobium is a member. Extractive Metallurgy of Niobium presents a vivid account of the metal through its comprehensive discussions of properties and applications, resources and resource processing, chemical processing and compound preparation, metal extraction, and refining and consolidation. Typical flow sheets adopted in some leading niobium-producing countries for the beneficiation of various niobium sources are presented, and various chemical processes for producing pure forms of niobium intermediates such as chloride, fluoride, and oxide are discussed. The book also explains how to liberate the metal from its intermediates and describes the physico-chemical principles involved. It is an excellent reference for chemical metallurgists, hydrometallurgists, extraction and process metallurgists, and minerals processors. It is also valuable to a wide variety of scientists, engineers, technologists, and students interested in the topic.

Hydrometallurgy of Rare Earths
Author: Dezhi Qi
Publisher: Elsevier
ISBN: 0128139218
Category : Technology & Engineering
Languages : en
Pages : 814
Book Description
Hydrometallurgy of Rare Earths: Extraction and Separation provides the basic knowledge for rare earth extraction and separation, including flow sheet selection criteria and related technology. The book includes the latest research findings on all rare earth separation processes, methods of controlling operation costs, and strategies that help lower wastewater and waste solid discharge. It discusses many real process parameters and actual situations in rare earth separation plants, also examining the basic principles, technologies, process parameters and advances and achievements in the area of rare earth extraction and separation. In addition, the book covers extraction separation theory as developed by Professor Guanxian Xu and Professor Chunhua Yan and the creative use of a computational simulation program to replace the bench scale and pilot plant tests and directly design rare earth extraction separation processes. - Outlines the theory of solvent extraction and separation of rare earths (REs) - Provides the necessary tools for a REs separation plant design - Includes a unique simulation program for the calculation of all process parameters - Includes Chinese nomenclature that is useful for identifying the various processes, also comparing it to the global literature
