摘要：

The hydrolytic processing of bismuth-containing nitrate solutions resulting in the production of high purity basic bismuth nitrate and carbonate, bismuth nitrate and bismuth oxide was studied. The developed technology is based on the oxidation of metallic bismuth followed by the dissolution of the obtained technical bismuth oxide in nitric acid and its purification from metal impurities by hydrolysis of Bi(NO3)(3) in aqueous solution under alkaline conditions or with excess water to produce basic bismuth nitrate. The pilot-plant trials confirmed the viability of the developed technology.
