Removal and Recovery of Uranium from Solid Wastes by Supercritical Carbon Dioxide Fluid Leaching Method
Supercritical CO2 fluid leaching (SFL) method using supercritical CO2 fluid containing a complex of HNO3 tri-n-butyl phosphate (TBP) was applied to removal of uranium from radioactive solid wastes. Sea sands, incineration ashes and porous alumina bricks were employed as matrixes of simulated solid wastes. Real radioactive incineration ash wastes and firebrick wastes were also subjected to the S...
متن کاملRecovery of Copper from Copper Slag and Copper Slag Flotation Tailings by Oxidative Leaching
Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide. Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings. Hydrogen peroxide was determined to be the best lixiviant. Thus, copper and iron extractions were ...
متن کاملIron Removal from Kaolins by Bacterial Leaching
Weathering of rocks generated large volumes of kaolin clays, quartz sands and micas, as well as other minerals, especially iron and titanium oxides. Kaolin is an economically important raw material often used in wide variety of ceramic applications, from high quality tableware and sanitaryware to electrical porcelain, tiles and glasses. There are some less common uses including glass fibre, whi...
متن کاملMineralogy and uranium leaching of ores from Triassic Peribaltic sandstones
The recovery of uranium and other valuable metals from Polish Peribaltic sandstones were examined. The solid-liquid extraction is the first stage of the technology of uranium production and it is crucial for the next stages of processing. In the laboratory experiments uranium was leached with efficiencies 71-100 % by acidic lixiviants. Satisfactory results were obtained for the alkaline leachin...
متن کاملBenzoic Compounds Removal from Aqueous Solutions by Acidic Silk: Equilibrium and Kinetic Study
Background & Aims of the Study: p-Chloronitrobenzene is a benzoic compound that widely used in many chemical industrials. p-Chloronitrobenzene may be absorbed through the skin and is suspected to causing cancer. So, developing an easy method to remove of it from the environment is necessary. Equilibrium isotherms and adsorption kinetics of p-Chloronitrobenzene onto modified sil...
