PROCESSO PARA SEPARACAO, POR MEIO DE UM AGENTE ORGANICO AMINADO,DO URANIO E DO MOLIBDENCIO CONTIDOS EM UM LICOR AQUOSO PROVENIENTE DO ATQUE SULFURICO DE UM MINERIO URANO-MOLIBDENIFERO |
摘要 |
<p>A process for separating by means of an organic agent the uranium and the molybdenum contained in an aqueous liquor originating from a sulphuric attack of an urano-molybdeniferous ore which involves placing the said attacking liquor in contact with an organic extraction solution containing at least one tertiary or secondary amine in an (amine)/(Mo) molar ratio of up to 0.8, separating the molybdenum-charged organic phase from the uranium-rich aqueous phase, treating the organic phase with an aqueous liquor containing at least one mineral agent in the form of alkaline and ammonium hydroxide and/or carbonates to form an aqueous solution which is concentrated in molybdate.</p> |
