Book Extraction and Recovery of Molybdenum and Rhenium from Molybdenite Concentrates by Electrooxidation

Download or read book Extraction and Recovery of Molybdenum and Rhenium from Molybdenite Concentrates by Electrooxidation written by Bernard J. Scheiner and published by . This book was released on 1976 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Federal Bureau of Mines has successfully demonstrated an electrooxidation-solvent extraction-carbon adsorption process for recovering molybdenum and rhenium from offgrade concentrates. The flow sequence consists of dissolution of metal values by electrooxidation, liquid-solid separation by thickening, acidification and chlorate ion removal by sulfur dioxide treatment, solvent extraction to concentrate the molybdenum and rhenium, separation of molybdenum and rhenium by carbon adsorption, and metal recovery by crystallization. Molybdenum and rhenium were recovered as ammonium paramolybdate and ammonium perrhenate.

Book Recovery and Separation of Molybdenum and Rhenium from a Process Solution

Download or read book Recovery and Separation of Molybdenum and Rhenium from a Process Solution written by D. D. Fischer and published by . This book was released on 1975 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recovery and separation of molybdenum and rhenium from a process solution was accomplished by a technique developed by the Federal Bureau of Mines involving a combined solvent extraction and activated carbon adsorption procedure. The processing sequence required treatment of the solution with SO2 to reduce the chlorate ion and adjust the pH prior to solvent extraction of molybdenum and rhenium with a tertiary amine. Molybdenum and rhenium were stripped from the organic phase with an NH4OH solution, and the strip solution was then passed through activated carbon to preferentially adsorb the rhenium. After washing entrained molybdenum from the column with a brine solution, rhenium was eluted with an MeOH-H2O mixture. The activated carbon was regenerated with water. Molybdenum was recovered as (NH4)6Mo--O24 by evaporating the column effluent. Rhenium in the column eluate was reextracted with a tertiary amine, stripped from the organic phase with dilute NH4OH, and recovered as NH4ReO4 by evaporating the strip solution. The final (NH4)ReO4 product contained
