; (5) After a certain time, the mixture was filtrated, then nickel-ammonia complex compound solution and leached residue were obtained. The main component of leached residue was ferric oxide, which can be directly used as raw materials for recovering iron. 2.3.2 Evaporation of ammonia The nickel-ammonia complex compound solution was heated to 80-100 ℃ to evaporate ammonia......
. In Zn(II)-NH3-Cl--H2O system, the ternary complexes containing ammonia and chloride increase the zinc solubility in neutral solution. There are three zinc compounds, Zn(OH)2, Zn(OH)1.6Cl0.4 and Zn(NH3)2Cl2, on which the zinc solubility depends, according to the total ammonia, chloride and zinc concentration. These thermodynamic diagrams show the effects of ammonia, chloride and zinc......
