METHOD OF CHEMICAL EXTRACTION OF CALCIUM Russian patent published in 2012 - IPC C25C3/02

Abstract SU 1840841 A1

FIELD: chemistry.

SUBSTANCE: invention relates to electrochemistry, particularly, to electrochemical extraction of calcium. Proposed method comprises extraction of calcium from melt of halides. Note here that in extraction, calcium monohalide is fed into melt. Electrolysis is performed at cathodic current density of 3-8 A/cm². Calcium monohalide is added in amount of 0.5-8.0 mol%.

EFFECT: increased current yield.
