Strontium Mining

Strontium Mining. Strontium is an alkaline earth metal and 15th most abundant element found on earth. It has similar characteristics as calcium and barium. Ore: The chief natural ores of strontium are Celestine and strontianite. It is found as strontium sulfate (SrSO4) in Celestine and strontium carbonate (SrCO3) in strontianite. Mining:
