Abstract: This article reported that a sort of ammonia-ammonium chloride solution was used to leach the inferior zinc oxide, to prepare a kind of feed additive-ZnCl2·4Zn(OH)2·H2O (TBZC). The percentage of the leaching was more than 90% under the leaching conditions: the molar ratio of NH3/NH4+ and TN/Zn were 1∶1 and 10∶1, respectively; and 40 ℃ lasted for 60 min. The product was characterized by chemical analysis, X-ray diffraction (XRD) and scanning electronic microscope (SEM). The results showed that the product was pure TBZC according to the requirement of GB/T 22546-2008. The method of the preparation was novel, simple, low-cost, safe, high-efficiency and environment-friendly, realizing the waste material could be reutilized, radically. More important fact was that the method could be used to synthesize a kind of new, qualified and stable product-TBZC .

Key words: ammonia chloride; inferior zinc oxide; feed additive; tetrabasic zinc cloride
