Available in PDF, EPUB and Kindle. Book excerpt: The basis for design and scale-up of mixer-settlers for the Dapex solvent extraction process was determined by a unit operaiions study in scale model units. Rate constants for uranium extraction involving stage efficiency, phase ratio, and residence time are directly propcrtional to the cube root of power input in the mixer. Typical mixing requirements for 90% stage efficiency are 30 hp/1000 gal and 2 min residence for extraction and 0.7 hp/1000 gal and 1.5 min for stripping. The scale-up of geometrically similar mixers is based on constant specific pcwer input. The flow capacity of gravity settlors is limited by a dispersion band, which increases exponentially with flow rate. The scale-up of settlers is based on constant flow rate of dispersed min for stripping. The scale-up of geometrically similar mixers is based on constant specific pcwer input. The fiow capacity of gravity settlers is limited by a dispersion band, which increases exponentially with flow rate. The scale-up of settlers is based on constant flow rate of dispersed phase per unit settler area and constant band thickness. The nominal flow capacity (50% of flooding) of the dispersed phase is approximately I gpm/-sq ft of settler area. Emulsions and solvent entrainment are minimized by control of mixing to form solvent-continuous dispersions. Operating data from two uranium mills confirm the scale-up relations over a range of flow rates of 200-fold for mixers and 1000-fold for settlers. (auth).

Available in PDF, EPUB and Kindle. Book excerpt: The basis for design of mixer-settlers for the Amex solvent extraction process, which uses long-chain amines dissolved in a hydrocarbon diluent for the recovery of U from acid sulfate solutions typical of those obtained in U ore processing, was determined by a unit-operations study in scale-model units. Long- term recycle tests in countercurrent equipment demonstrated the stability of amines and the general feasibility of the Amex process. Mass transfer rates of U for both extraction and stripping are large, and greater than 90% stage efficiency was readily obtained. The flow capacity of gravity settlers is generally limited by a dispersion band, which increases exponentially with flow rate. The scaleup of settlers is based on the constant flow rate of dispersed phase per unit settler area and constant band thickness. The nominal flow capacity (50% of flooding) ranged from 0.4 to 0.8 gpm/ft/sup 2/, depending on the type of dispersion and amine used. The capacity can be increased (fourfold) by using packing wetted by the dispersed phase. Emulsion stabilized by silica (the worst offender) can be minimized by controlling the mixing in order to form solvent-continuous dispersions, which also minimizes entrainment of solvent in the aqueous waste.

Book excerpt: 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
