Co-extraction and separation of zirconium and hafnium by long-chain amines from sulphate media.
The extraction of Zr and Hf from sulphuric acid systems by solutions of Primene JMT (a long-chain primary amine) in kerosene, is described. The effect of contact time, free acidity, solvent concentration and temperature, has been thoroughly examined. A rapid improved method for HfZr separation is suggested.
