| titleOfInvention | A kind of processing method utilizing the environmental protection of electrolytic zinc waste residue to produce feed level zinc sulfate |
| abstract | The invention discloses a kind of processing method utilizing the environmental protection of electrolytic zinc waste residue to produce feed level zinc sulfate, after first electrolytic zinc waste residue being dissolved with 60 DEG C ~ 80 DEG C hot water stirs, with pH to 4.5 ~ 5.1 of saturated milk of lime clear liquid regulator solution, filtration remove portion precipitates, filtrate is heated to 80 DEG C ~ 90 DEG C again, pass into air or oxygen, most of iron contamination in removing solution, by adding the trace iron impurity in small amounts calcium powder or secondary zinc oxide powder removing solution in the solution, again filtrate is added metal zinc under the condition of pH4.2 ~ 4.5 after filtration, further removing residual gravity metallic impurity, activity charcoal powder and sequestrant is added again in solution, a small amount of organic impurity in removing solution, after filtration, pure solution of zinc sulfate condensing crystal is produced feed grade Zinc Sulphate Heptahydrate or sulfuric acid monohydrate zinc product, the inventive method is with electrolytic zinc waste residue for raw material, and full cut-off road cyclic production, environmental friendliness, production cost is low, high financial profit. |
