| titleOfInvention | Process for cupric sulfate monohydrate |
| abstract | The present invention is obtained by adding calcium carbonate or sodium hydroxide to the waste liquid for corrosion of an electronic circuit board containing copper chloride to obtain crude basic copper carbonate or copper oxide, and by adding concentrated sulfuric acid directly without solvent to the crude basic copper carbonate or copper oxide, and reacting it gradually. It is to provide a method for producing copper sulfate monohydrate (CuSO 4˙ H 2 O) directly without going through copper sulfate and pentahydrate. |
