Effect of operational parameters and internal recycle on rhenium solvent extraction from leach liquors using a mixer-settler
The extraction of rhenium from molybdenite roasting dust leach solution was performed using a mixersettler extractor by tributyl phosphate (TBP) diluted in kerosene as the extractant. In the single-stage extraction experiments, effect of the aqueous to organic phase ratios, Qa/Qo, and the number of extraction stages, N, on the rhenium extraction was studied. It was found that using the phase ra...
متن کاملImprovement of the Solvent Extraction of Rhenium from Molybdenite Roasting Dust Leaching Solution using Counter-current Extraction by a Mixer-settler Extractor (TECHNICAL NOTE)
Continuous counter-current extraction of rhenium from roasting dust leach liquor was carried out using a mixer-settler extractor. Tributylphosphate was used as the extractant diluted in kerosene. The effects of the flow rates and extraction stages number were investigated. The extraction efficiency was affected by the flow rates of the aqueous and organic phases, and its mechanism was qualitati...
متن کاملThe Effects of Operational Parameters on the Efficiency of a Mixer-Settler Extractor
The effects and influences of various operational parameters on the efficiency of mixer-settlers are thoroughly studied in this paper. One of the most important factors in designing a mixer-settler is to obtain an optimum operational extraction and overall efficiency. These two factors are dependent on various parameters such as impeller shape, size and speed of impeller, baffle size, residence...
متن کاملSolvent Extraction Studies on Uranium using Amine Based Extractants and Recovery from Low Grade Ore Leach Liquors
Neste estudo, extratores à base de amina (Alamine 336, Alamine 308, Alamine 304 e Aliquat 336) diluídos em querosene foram usados para extração de urânio e separação de outros elementos associados. Alamine 336 foi o melhor extrator para o processo de extração de urânio de soluções de sulfato quando comparado com outros reagentes à base de amina, Alamine 308, 304 Alamine 336 e Aliquat 336. O com...
متن کاملEvaluation of the Effect of Mixer Settler Baffles on Liquid-liquid Extraction via Cfd Simulation
Mixer-settlers typically contain an impeller mounted on a shaft, and optionally it can contain baffles. In this study, the effect of the number of baffles on the separation characteristics of the system, and the effect of blade width and inlet velocity on baffles number have been investigated. Computational Fluid Dynamics (CFD) model is developed to predict the separation characteristics. The m...
