Book The Relix Process for the Resin in pulp Recovery of Uranium

Download or read book The Relix Process for the Resin in pulp Recovery of Uranium written by and published by . This book was released on 1981 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Relix process is based on direct contact between an ion-exchange resin and undiluted pulp, thus avoiding prior solid-liquid separation. The resin particles float near the surface of the pulp, forming an inverted fluidized bed with the pulp flowing downwards. The basic idea was demonstrated on a full-scale pachuca tank at Stilfontein Gold Mine in 1970, followed by a small-scale demonstration run in a laboratory at the National Institute for Metallurgy. A pilot plant based on a throughput of 60 tons of ore per day was subsequently operated at West Driefontein Gold Mine for several periods over two years. Although the plant proved operable from a mechanical point of view, the metallurgical performance was not up to expectation. The basic cause of the poor metallurgical performance was shown to be backmixing of both the resin and the pulp between stages. The values obtained for resin losses were inconclusive. Further development of resin-in-pulp processes for the recovery of uranium should be focused on the performance of various techniques for the screening of resin from pulp.

Book The Engineering of a Resin in pulp Contactor for the Recovery of Gold and Uranium from High density Slurries

Download or read book The Engineering of a Resin in pulp Contactor for the Recovery of Gold and Uranium from High density Slurries written by and published by . This book was released on 1994 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional hydrometallurgical processes for the extraction of uranium involve leaching, followed by solid-liquid separation and then recovery from solution by ion exchange or chemical precipitation. Although researchers have attempted since the 1950s to develop processes that eliminate the solid-liquid separation step by using resin-in-pulp (RIP) for the recovery step, they have succeeded in doing this only for 'thin' pulps. This is a consequence of the twin difficulties of resin-pulp separation and resin degradation in 'high-density' slurries. Various methods of resin-in-pulp agitation, transport, and separation were tested at Mintek, and the results clearly indicated that air agitation, airlifts, and sieve bends, respectively, are the best solutions. This paper describes the systematic pilot-scale study on which these conclusions are based, and indicates that significant cost benefits could result when this technology is applied to the recovery of dissolved species such as gold and uranium from leach pulps.

Book Recovery of Uranium from Vitro Leach Liquors by Ion Exchange Part II Cyclic Column Tests Comparing IRA 400 and XE 75 Resins and Cyclic Testing of a Resin in Pulp System

Download or read book Recovery of Uranium from Vitro Leach Liquors by Ion Exchange Part II Cyclic Column Tests Comparing IRA 400 and XE 75 Resins and Cyclic Testing of a Resin in Pulp System written by and published by . This book was released on 1954 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: A three-column ion exchange test program on Vitro leach liquors was run to compare the performance of IRA-400 and XE-75 resins with respect to loading, elution, and poisoning characteristics. When a high molybdenum liquor was used as feed to the columns, molybdenum poisoning was shown to occur with both IRA-400 and XE-75 resins; however, this poisoning action was much less rapid and less extensive in the case of XE-75. In this respect the XE-75 was found to be similar to Permutit SE. The use of a six percent caustic regenerant completely restored the ion exchange properties of the poisoned XE-75 resin. A cyclic resin-in-pulp process for recovery of uranium from Vitro leach liquors and pulps was studied. The Winchester cell was employed for this investigation in conjunction with XE-123 resin - - a plust 20 mesh resin with the exchange characteristics of XE-75. Performance data, including the effects of molybdenum poisoning, indicate that a 12 cell string may be used effectively with seven cells on exhaustion and five on elution.
