generated using kerosene as a solvent, HEHPEHE as an extractant, sodium dodecyl benzene sulphate (SDBS) as a surfactant in aqueous phase and polyoxyethylene sorbitol anhydride monolaurate (Tween-20... Kelong Chemical Company, China. The solvent kerosene (AR grade) was from Luoyang Zhongda Chemical Company, China. Chromic nitrate (Cr(NO)3) (AR grade) was purchased from Kelong Chemical Company, China......
% sulfonated kerosene. Approximately 99.93% of W was extracted and ammonium tungstate solution containing 193 g/L W was obtained with a stripping rate of 98.10% under the optimized conditions. Key words... phosphate (TBP, analytical grade) with commercial sulfonated kerosene as the solvent for extraction. The other reagents used in this work were of analytical grade. 2.2 Methods Leaching experiments were......
hexametaphosphate, 4.5 L/t oleic acid, and 4.5 L/t kerosene, significant amount of fine magnetite particles adhered to the pentlandite surface, while trace amount of coating was found on serpentine surfaces...] by adding dodecylamine (7.2×10-6 mol/L), kerosene (2.5 L/t), and pine oil (250 g/t), adjusting pH value, and optimizing the amount of magnetite. Quartz particles were strongly coated by fine magnetite......

. Optimum conditions are obtained as follows: 20% P204 (volume fraction) diluted with kerosene at room temperature, pH 3.0, and varying organic/aqueous (O/A) phase ratio 1:1. The extraction rate... mass is 322 and the density at 20 °C is 0.974 g/cm3. The extractant was used without further purification. In all experiments, aviation kerosene was used as organic diluent. All experiments were......
