1.3 Synthetic Route

Metal copper method: 30%~32% nitric acid is added to the acid-resistant reactor with stirring, and copper chips are slowly added under stirring for reaction. After the reaction is carried out for 8h, the solution is heated to 60~70 °C, nitrogen oxide gas is expelled, and the reaction is until no yellow smoke is produced. Put the solution into the storage tank, dilute it with water, and then filter, clear the filtrate with nitric acid acidification after vacuum evaporation, concentrate at 60~70 °C to the relative density of the solution 1.78~1.8, and then cool crystallization, centrifugal separation, drying to prepare copper nitrate finished product.
Copper oxide method: use copper-containing scraps (containing metal copper, copper sulfide, copper sulfate, etc.) roasted at 600 °C for 6h, the generated copper oxide is acidified with dilute sulfuric acid to obtain copper sulfate solution, after clarification, filtration, the clear filtrate is replaced with iron filings, the metal copper is separated by sedimentation, and then the iron filings mixed in the metal copper powder are removed by elution, and then separated and roasted to obtain black copper oxide powder.
Add water, mother liquor, concentrated nitric acid to the acid-resistant reactor with stirring, slowly add copper oxide at 25~30 °C under stirring until no yellow smoke occurs, the solution is diluted with water to 30 °Bé, vacuum suction filtration. The clear filtrate was added to hydrogen peroxide, and Ph4~4.5 was adjusted, and then clarified and filtered to remove the iron hydroxide precipitate. After adding the clear liquid to nitric acid acidification, it is concentrated by evaporation, cooled and crystallized, centrifuged and dried to obtain a finished copper nitrate product.
