• Bismuth Production Element Bismuth, Bi, Poor Metal

    When the acid is almost completely neutralised, the lye is removed, concentrated and poured into milk of lime. Bismuth trioxide is thus precipitated and calcium nitrate remains in solution 2Bi(NO 3) 3 + 3Ca(OH) 2 = Bi 2 O 3 + 3Ca(NO 3) 2 + 3H 2 O This process is used mainly for the production of salts of bismuth.
