Physiological use of Bismuth

Submitted by admin on Fri, 10/26/2018 - 09:32

Bismuth exists in nature in the form of free metals and minerals. The metal Bismuth is obtained by calcination of minerals into Bismuth trioxide, followed by co-thermal reduction with carbon, and high-purity Bismuth can be obtained by fire refining and electrolytic refining.
