time is 90 min. Under the conditions, extractions of Ni and Co reach 91.5% and 82.3%, respectively. Key words: nickel laterites; nickel; cobalt; chloridizing segregation; magnetic separation... and reach a maximum. Because nickel and cobalt chloride can dissolve in water and lose later in wet magnetic separation. Therefore, it is necessary to control the chloridizing time beyond 90 min at least......
Dialkyl phosphinic acids: Synthesis and applications as extractant for nickel and cobalt separation LI Lin-yan(李林艳)1, 2, XU Sheng-ming(徐盛明)1, JU Zhong-jun(居中军)1, ZHANG Zhang (张 章)3, LIAO Fu-hui(廖... in the following sequence from large to small: DHPA, DDPA and DTMPPA, which indicates that the separation ability for cobalt and nickel ascends from DHPA, DDPA to DTMPPA. Key words: dialkylphosphinic acid; free......

Process development for the direct solvent extraction of nickel and cobalt from nitrate solution: aluminum, cobalt, and nickel separation using Cyanex 272Zela T.Ichlas,Don C.IbanaLeaching... the second extraction step involved the separation of cobalt along with manganese from nickel. The experimental results showed essentially quantitative removal of aluminum(>97%) and zinc(>99......
that extraction rate of metal ions increases with increase of aqueous phase pH value. The pH0.5 value difference of 1.40 with PC88A indicates the possible separation of cobalt and nickel. Increase of the concentration of the solvent can enhance the percentage extraction of both metal ions. Improvement of temperature is beneficial to extraction separation of cobalt and nickel. Extraction and stripping......
