| titleOfInvention | Method for producing nano calcium zincate by using leaching residue of electrolytic zincate method |
| abstract | The disclosure relates to a method for producing nano calcium zincate by using leaching residue of an electrolytic zincate method, which comprises a leaching step, an optional purification step, a desulfurization step, a calcium zincate synthesis step, an optional rinsing step and a drying step. The method disclosed by the invention realizes secondary utilization of leaching residues while solving the environmental protection problem, realizes resource utilization while solving the pollution of various heavy metals, does not need ammonia distillation, is simple and easy to implement, greatly reduces the energy consumption of the process, changes sulfate ions serving as pollution sources into valuables by calcium sulfate conversion, realizes calcium zincate synthesis in the ammonia-zinc environment for the first time, has the comprehensive advantages of energy conservation, environmental protection and low cost compared with the traditional calcium zincate preparation process, and is suitable for large-scale industrial application. |
