method of extracting calcium from its ore

  • How calcium is extracted from its ore?

    Jun 09, 2020 · How calcium is extracted from its ore? In order to isolate pure calcium, it must be extracted through electrolysis, a technique that uses a direct electrical current to separate elements from their naturally occurring sources. Once isolated, calcium is quite reactive and will form a grayish-white oxide and nitride coating when exposed to air.
