GmbH Germany, part of Springer Nature 2021 Abstract: Biological column leaching of Ni from low-grade Ni ore was studied, and the effects of ore particle size on leaching rate were investigated. The Ni......
Adsorption of erbium(Ⅲ) on D113-Ⅲ resin from aqueous solutions:batch and column studies YAO Caiping1,XIONG Chunhua1,MENG Yuan1,SHEN Chen1 (1.Department of Applied Chemistry,Zhejiang Gongshang... was endothermic in nature. Thomas model was applied to experimental column data to determine the characteristic parameters of column useful for process design. Er(Ⅲ) ion could be eluted by using the 4.0 mol/L HCl......
phosphoric acid(D2EHPA) in kerosene solution were measured by the single drop technique. The influences of hydrogen ion concentration, gadolinium ion concentration, extractant concentration, column......

Axial force and stress and shaft resistance of two T-shaped soil-cement deep... of the lower piles of 10.5 m length just accounts for 11.11%.Key words:T-shaped soil-cement deep mixing column; load tests; variable section; column body stress; column lateral friction resistance......
+ migrated from 40-50 to 20-30 cm of the column, presenting a high migration capacity. The migration capacity of Ca2+ was lower and accumulated at 30-40 cm of the column. initially distributed at 20-30 cm of the column, subsequently transported to 30-40 cm of the column, and finally returned to 20-30 cm of the column along with evaporation. was originally distributed at 40-50 cm, but finally......
