\u0130lk olarak 1808 y\u0131l\u0131nda Berzelius ve Pontin, civa i\u00e7erisindeki CaO\u2019in (lime) elektrolizi ile kalsiyum amalgam (cival\u0131 maden ala\u015f\u0131m\u0131) elde etmi\u015f. Daha sonra Humphry Davy taraf\u0131ndan ilk defa saf olarak izole edilmi\u015ftir.<\/p>\n
Kalsiyum do\u011fada saf olarak bulunmaz. En fazla kire\u00e7 ta\u015f\u0131nda (CaCO3) bulunur. Mermer ve kalsit te ayn\u0131 form\u00fcle sahiptir. En \u00f6nemli mineralleri dolomit (CaCO3 MgCO3), apatit (3Ca3(PO4)2), gibs (CaSO4.2H2O) dir. <\/p>\n
Kalsiyum saf olarak erimi\u015f kalsiyum klor\u00fcr\u00fcn elektroliz ile elde edilir.<\/p>\n

Kalsiyum klor\u00fcr a\u015fa\u011f\u0131daki reaksiyon ile elde edilir. <\/p>\n
CaCO3 + 2HCl \u00e0 CaCl2 + H2O + CO2 <\/p>\n
Di\u011fer bir elde edili\u015f y\u00f6ntemi ise kalsiyum oksidin (CaO) al\u00fcminyum ile veya kalsiyum klor\u00fcr\u00fcn metalik sodyum ile indirgenmesi ile elde edilir. <\/p>\n
