摘要： A substantially iron-free copper nitrate solution is made by dissolving a copper-containing solid catalyst composition such as a used copper-zinc oxide-alumina methanol synthesis catalyst in nitric acid and controlling the acid concentration at a level such that any iron oxide present in the composition remains substantially undissolved. The acid concentration during dissolution is preferably under 6 molar. Alternatively or additionally the tefminal pH is greater than 1.0. The resulting solution is pure enough for reconversion to catalyst by co-precipitation.

摘要： Disclosed in the invention is a method for separating zirconium oxide/hafnium oxide by pyrometallurgy. The mixture of zirconium oxide/hafnium oxide, carbon and pure bromine react one hour at 650°C to get the zirconium and hafnium bromide, then the zirconium and hafnium bromide are added to molten salt mixture for distillation separation, and the rectifying tower bottom is maintained two hours below 357°C, to get the non-target substance; and maintained five hours at 357°C to collect the target substance zirconium tetrabromide; the residue in the reactor is retained, then rectification separation is performed in the same device, heated to 400°C to retain more than five hours, to get hafnium tetrabromide, then the zirconium tetrabromide and hafnium tetrabromide are replaced by magnesium to get the pure zirconium and pure hafnium. Since the separation effect is good and equipment investment is economical, it is easy to achieve industrialization. This invention technology can fill the gap in china, to make great contributions to the localization of zirconium and hafnium nuclear materials.
