Book Synopsis Recovery and Separation of Molybdenum and Rhenium from a Process Solution by : D. D. Fischer
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

Book Synopsis Recent Advances in Mining and Processing of Low-Grade and Submarginal Mineral Deposits by : Sam Stuart
Download or read book Recent Advances in Mining and Processing of Low-Grade and Submarginal Mineral Deposits written by Sam Stuart and published by Elsevier. This book was released on 2013-10-22 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent Advances in Mining and Processing of Low-Grade and Submarginal Mineral Deposits reviews advances in the mining and processing of low-grade and submarginal mineral deposits, taking into account the environmental considerations that increasingly are being regarded as a necessary prerequisite to acceptable mineral resources development. The focus is on marginal and sub-marginal ores, as well as ores of above normal cut-off grades which for some reason cannot be mined and/or processed economically at current technological or economic levels. This book is comprised of 12 chapters and begins with an overview of low-grade ore potential, followed by a discussion on the theoretical and practical aspects of in situ mining. Block cave-in place leaching, biological leaching of sulfide ores, and nuclear chemical mining of primary copper sulfides are also considered. Subsequent chapters explore the economics and safety of nuclear chemical copper mining; hydrometallurgy of low-grade copper ores; trends in process metallurgy; and environmental aspects of mining and processing low-grade and submarginal mineral deposits. This monograph should be of interest to mining officials and professionals.
