Method for separating individual Ca and Mg from solutions containing Ca and Mg, CaC2O4 and MgC2O4 produced thereby, and CaO and MgO prepared thereby

摘要

separation method in the present invention is to be , more specifically, calcium ion and magnesium selective method for separating calcium and magnesium in calcium and magnesium -containing solution to selectively remove calcium and magnesium from the solution , each ion is present in the co-existence , the separation obtained by the method of calcium oxalate and magnesium oxalate , and the oxalate relates to a calcium oxide and magnesium oxide obtained from the rate . ;
