The Bureau method involved electrowinning of a calcium-tin alloy followed by electrorefining to produce calcium metal. In the electrowinning cell, cacl2 was fed to a kcl2-cacl2 electrolyte. The calcium was electrowon at 650 deg c into the pure molten tin hode until the hode contained 7.5 Wt pct ca. Current efficiency for electrowinning averaged over 90 pct.
