Preparation method of basic copper sulfate

The invention relates to a preparation method of basic copper sulfate, which mainly comprises the following steps: solution preparation: adding a proper amount of copper sulfate and urea into ionizedwater to prepare a copper sulfate solution and a urea solution, mixing according to the volume ratio of 1: 1-1.2, and stirring, heating treatment: sealing and heating the stirred mixed solution for 4hto 24h, and enabling the mixed solution and the stirred mixed solution to fully react to obtain a solution containing basic copper sulfate crystals, cooling: putting the mixed solution after the reaction into a cooling chamber for cooling, filtering to obtain filtrate, and collecting basic copper sulfate crystals, and washing: mixing water and the basic copper sulfate crystal obtained in the stepS3 and washing for 1-3 times according to the solid-to-liquid ratio of 1: 1-2, and then filtering and collecting to obtain the basic copper sulfate crystal. The method has the advantages of short process route, simple operatio
