[carbonato]tetrahydroxytri-Nickel - Production method
The sodium carbonate method is based on the ratio of sulfuric acid to nitric acid of 3:1. Nitric acid is added in sulfuric acid to prepare mixed acid, and then metallic nickel is added to react with nitric acid to generate nickel nitrate, then react with sulfuric acid to generate nickel sulfate solution, and then add soda ash to react to generate basic nickel carbonate. After filtration, concentration, cooling crystallization, and centrifugal separation, a finished basic nickel carbonate product is obtained. Its
